What is Carbon Fiber?

What is Carbon Fiber?

Over 30 years ago, carbon fiber was considered a cutting-edge, space-age material that was prohibitively expensive and reserved for aerospace applications. Today, it has become a versatile and sought-after material, widely used in industries such as wind energy, automotive manufacturing, sporting goods, and more. Carbon fiber is renowned for being incredibly strong and lightweight, making it an ideal replacement for traditional materials like steel and plastic in high-end applications—especially in performance-driven sectors like motorsports and luxury sports cars.

At its core, carbon fiber is made of carbon—the most abundant element on Earth. Through an intricate process, the carbon is treated, spun into ultra-thin strands, and woven into fabrics. These strands are then bonded together using high-strength resins, cured under specific conditions to enhance durability, and finally cut and shaped into components. The result is a material that excels in strength-to-weight ratio, making it highly advantageous for engineering precision parts.


How is Carbon Fiber Made?

Carbon fibers are derived from base materials such as acrylic fibers (similar to those used in textiles like clothing and blankets) or from pitch, which is obtained from coal tar or petroleum byproducts. The production process involves bundling thousands of carbon fibers into threads, which are then woven into a cloth-like fabric. When this fabric is combined with resin-based epoxies, it forms an extremely rigid and durable composite material.

In terms of strength, carbon fiber is approximately ten times stronger than steel when measured by weight and significantly more resistant to deformation. For parts of comparable size, carbon fiber components can be twice as strong as steel while weighing only a quarter as much. This substantial reduction in weight can enhance a vehicle’s speed, performance, and sometimes even its safety by improving overall handling and reducing the strain on mechanical systems.


What is ‘Grade A’ Carbon?

Although there is no universal or official grading system for carbon fiber, the term “Grade A” is often used by manufacturers to indicate superior quality. However, this designation is typically a marketing term rather than an industry-standard certification. It is meant to reassure consumers that the product is made using premium materials and exceptional craftsmanship.

At Scopione, we primarily use carbon fiber sourced from Toray Industries Inc., one of the world’s leading suppliers of advanced composite materials. Toray has an outstanding reputation for producing top-quality carbon fiber, which is used by many of the world’s foremost automakers. By using such high-quality carbon fiber, we ensure that our products offer the durability, strength, and precision that customers expect from premium components.

What is the Difference Between Wet and Dry (Pre-preg) Carbon Fiber?

Among the many terms associated with carbon fiber, “dry” and “wet” carbon fiber are two of the most commonly misunderstood. These terms refer to the production methods used to manufacture carbon fiber products. Each approach results in significant differences in weight, strength, and overall quality. Dry carbon fiber is made using pre-preg (pre-impregnated) resin fibers already integrated into the carbon material. In contrast, wet carbon fiber involves coating the carbon cloth with resin by hand before curing. Understanding the distinctions between these two types is essential for making an informed decision that suits your specific needs.


What is Dry Carbon Fiber?

Dry carbon fiber is formed using pre-preg carbon fiber materials, where the carbon fibers have been pre-impregnated with resin. This material is placed into a mold and then sealed in a vacuum chamber to undergo the curing process. This method minimizes waste and produces a lighter and more consistent carbon fiber product compared to the wet process. The vacuum process helps to eliminate pinholes and air pockets, resulting in a smoother, stronger, and more uniform finish. Dry carbon fiber products are regarded as the highest quality available, but this comes at a higher cost—often three to four times that of wet carbon fiber.

Dry vs Wet Carbon Fiber

Advantages of Dry Carbon Fiber:

  • Significantly lighter (up to 60% lighter than wet carbon fiber)
  • Increased strength and durability
  • Superior manufacturing process with minimal imperfections
  • Enhanced cosmetic appearance with a sleek, dry finish

Disadvantages of Dry Carbon Fiber:

  • Much more expensive to produce (three to four times more costly than wet carbon fiber)
  • Requires maintenance to prevent fading unless properly coated with a UV-protective clear coat

What is Wet Carbon Fiber?

Wet carbon fiber is produced using a different, more cost-effective manufacturing process. In this method, dry carbon fiber cloth is manually laid into a mold. A resin mixture, typically a blend of two parts resin to one part carbon, is then applied over the cloth. The mold is sealed in a vacuum bag and heated to cure the resin. While this process allows for lower production costs, it also introduces a higher likelihood of air bubbles and inconsistencies, such as wavy fiber patterns. As a result, wet carbon fiber products are heavier and less durable than their dry counterparts.

Advantages of Wet Carbon Fiber:

  • Lower production cost makes it more affordable for consumers
  • Shiny, “wet-look” finish can be visually appealing

Disadvantages of Wet Carbon Fiber:

  • Heavier and weaker compared to dry carbon fiber
  • Prone to fading over time unless properly maintained
  • Higher risk of imperfections, such as air pockets and uneven weaves

What is Pre-preg Carbon Fiber?

The term “pre-preg” refers to carbon fiber material that has been pre-impregnated with resin. Pre-preg carbon fiber comes in varying resin content levels, typically measured in grams per square meter (GSM). The amount of resin does not necessarily indicate the quality of the carbon fiber itself, but it does influence the material’s flexibility and curing properties.

To create a pre-preg carbon fiber component, layers of the material are placed into a mold. The mold is then covered with a breathable plastic sheet attached to a vacuum system, which removes excess air. The entire assembly is placed in an autoclave oven for curing. During this process, the mold is subjected to temperatures ranging from 350°F to 800°F and pressures of 80 to 100 psi. This high-pressure environment eliminates air pockets and non-carbon impurities, ensuring the final product is strong and lightweight. Once the curing cycle is complete, the product is allowed to cool, solidifying into a durable carbon fiber part.

The autoclave curing process is essential for creating high-performance dry carbon fiber components, making them stronger, lighter, and more resilient than those produced by the wet method.


Key Differences at a Glance:

FeatureDry (Pre-preg) Carbon FiberWet Carbon Fiber
WeightSignificantly lighterHeavier
StrengthStronger and more durableWeaker due to air pockets
CostMuch more expensiveMore affordable
ManufacturingUses pre-impregnated resinResin applied by hand
AppearanceMatte or dry finishShiny, glossy finish
ConsistencyMinimal imperfectionsProne to inconsistencies

Understanding the differences between dry (pre-preg) and wet carbon fiber can help you make the best choice based on your needs and budget. If performance, strength, and weight reduction are your priorities, dry carbon fiber is the superior option despite its higher cost. However, if budget constraints are a concern and you are looking for a more aesthetically glossy finish, wet carbon fiber may be a suitable alternative. Proper maintenance, such as applying a clear coat to prevent UV damage, can extend the lifespan of both types. By evaluating the pros and cons of each type, you can choose the right carbon fiber product for your application.

What is a Weave?

The term “weave” refers to the pattern formed when carbon fiber strands, known as tows, are woven into a fabric. There are many types of carbon fiber materials available, and they are typically identified by their weave pattern and tow size. Understanding the full meaning of “weave” is essential for properly evaluating and selecting carbon fiber parts for specific applications.

Plain vs Twill | What is a Weave?

Plain Weave

A plain weave carbon fiber sheet has a symmetrical, checkerboard-style appearance. In this weave, the tows are woven in an over-under pattern, creating a balanced, uniform structure. The short distance between the interlaces provides the plain weave with a high level of stability—the ability of the fabric to maintain its weave angle and fiber orientation. This inherent stability makes plain weave carbon fiber ideal for flat sheets, tubes, and simple 2D curves.

However, the same stability limits its ability to conform to complex, curved surfaces. The rigid structure of the weave reduces its pliability, making it less suited for layups involving intricate contours. Additionally, the frequent interlacing creates sharp crimps (the angles the fibers form at each interlace point). These crimps can introduce stress concentrations, potentially weakening the part over time, especially in high-stress applications.

Twill Weave

Twill weave carbon fiber is more pliable than plain weave and can conform to complex contours while maintaining good fabric stability. This weave is popular in both structural and cosmetic applications due to its balance of formability and durability. A key feature of the twill weave is its distinctive diagonal pattern, known as the “twill line.” This pattern is created by the tows passing over and under multiple other tows in a staggered sequence.

In a 2×2 twill weave, for example, each tow passes over two tows and then under two tows. Similarly, a 4×4 twill weave follows the same principle, passing over and under four tows. The longer distances between interlaces result in fewer crimps, which reduces the risk of stress concentrations and enhances the material’s strength. This characteristic also contributes to the weave’s ability to withstand wear and minimize weak points over time.

Due to its visually appealing texture and versatility, the 2×2 twill weave is one of the most recognizable patterns in the automotive and aerospace industries. It is often used in high-end car components, accessories, and decorative carbon fiber elements.

Choosing the Right Weave

When selecting a carbon fiber weave, it is important to consider the specific requirements of the project. Plain weave offers superior stability for flat and simple shapes but may be prone to stress points due to crimping. On the other hand, twill weave provides a combination of flexibility and strength, making it a better choice for parts with complex contours or for those requiring an attractive surface finish.

By understanding the unique properties of each weave, you can make more informed decisions and optimize the performance, durability, and aesthetic appeal of your carbon fiber components.

What is the Difference Between 1×1 and 2×2 Weaves?

The difference between 1×1 and 2×2 weaves lies in the pattern of the weave itself. 1×1 weaves resemble a square or checkerboard pattern, while 2×2 weaves have a distinct diagonal appearance. With carbon fiber becoming increasingly popular, many people have questions about the different carbon fiber weaves and whether any particular weave is superior for specific applications.

1×1 Weave

The 1×1 weave carbon fiber is woven in a symmetrical, tightly-knit pattern, which gives it excellent strength and a clean, uniform look. This type of weave is commonly used in both OEM (Original Equipment Manufacturer) and aftermarket automotive parts. It is easily recognizable due to its checkerboard-like pattern.

One of the primary advantages of the 1×1 weave is its stability. The tight weave makes the fabric less prone to distortion during handling, ensuring a consistent and professional appearance. However, this tightness comes at the cost of flexibility. The 1×1 weave is less pliable, making it challenging to drape over complex molds or contours. This limitation can make it unsuitable for certain intricate shapes.

An example of the 1×1 weave’s use is in the carbon fiber roofs of high-performance cars such as the BMW M3. These applications benefit from the strength and appearance of the 1×1 weave, where fewer complex curves are involved.

What is a Weave?

2×2 Weave

The 2×2 weave is the most common weave in the automotive industry, especially for aftermarket parts like carbon fiber hoods, splitters, and rear diffusers. It features a diagonal pattern, making it visually distinct from the checkerboard look of the 1×1 weave.

One key advantage of the 2×2 weave is its flexibility. The diagonal pattern allows the fabric to more easily conform to complex shapes and angles, making it ideal for parts with intricate designs, such as rear diffusers with integrated fins and sharp corners. This adaptability makes it the preferred choice for parts that require a high degree of draping over molds.

Comparing 1×1 and 2×2 Weaves

Both 1×1 and 2×2 weaves are strong and lightweight, making them excellent choices for automotive use. However, each weave has its own strengths and limitations:

  • 1×1 Weave:
    • Strengths: High stability, resistance to distortion, and a refined checkerboard aesthetic.
    • Weaknesses: Less flexible and harder to mold into complex shapes.
    • Cost: Typically more affordable due to the simplicity of the weave pattern and the ease of the molding process.
  • 2×2 Weave:
    • Strengths: Greater flexibility, able to conform to complex molds, and an attractive diagonal pattern.
    • Weaknesses: Slightly less stable than the 1×1 weave due to the looser structure.
    • Cost: Slightly higher due to the complexity of manufacturing and its adaptability to intricate designs.

Other Carbon Fiber Weave Patterns

While 1×1 and 2×2 weaves are the most commonly used in the automotive industry, there are several other weave patterns available, each with its own unique characteristics:

  • Four-Harness Satin: Offers a smooth finish and moderate flexibility.
  • Five-Harness Satin: Similar to the four-harness satin but with added drapability.
  • Eight-Harness Satin: Extremely flexible, making it suitable for very complex shapes.
  • 4×4 Weave: A balanced weave that offers more flexibility than 1×1 but retains strength.
  • Unidirectional Weave: Reinforces strength in a single direction, often used in structural components.
  • Triaxial Weave: Provides multidirectional reinforcement for enhanced strength and durability.

In summary, the choice between 1×1 and 2×2 weaves depends largely on the specific requirements of the application. For simple, flat, or gently curved parts where appearance and rigidity are priorities, the 1×1 weave is a great option. For parts with more complex shapes and angles, the 2×2 weave is the better choice due to its superior flexibility. Ultimately, both weaves provide excellent strength and lightweight properties, making them popular choices for both aesthetic and performance-driven automotive parts.

What are Epoxy, Vinylester, and Polyester Resins?

Before purchasing carbon fiber parts, it is essential to understand the resins used in their construction. This knowledge helps you gauge their effectiveness and value for the price you pay. Three primary types of resins are commonly used in automotive carbon fiber parts: epoxy, vinylester, and polyester. Understanding their properties will help you make an informed decision about which brand and type of carbon fiber parts best suit your needs.

Epoxy vs Vinylester vs Polyester

Epoxy Resin

Epoxy resin is the most expensive of the three types but also the strongest and most durable. Epoxy is a polymer resin that hardens when combined with a catalyst, forming a robust and resilient matrix. This resin binds exceptionally well to carbon fiber, Kevlar, and fiberglass, creating a solid, leak-proof barrier. Key features of epoxy resin include:

  • Tensile Strength and Durability: Epoxy offers the greatest tensile strength, stiffness, and resistance to fatigue.
  • Resistance to Degradation: It is highly resistant to water damage, osmosis, and chemical wear compared to polyester or vinylester resins.

Epoxy resins consist of two parts—a resin and a hardener—which must be mixed in precise proportions for maximum effectiveness. This differs from vinylester and polyester resins, which are single-component substances that only require a small amount of catalyst.

Formulations and Applications

Epoxy resins come in various formulations that cure at different temperatures and speeds. Additionally, specialized temperature-resistant epoxy compounds are available for high-performance applications. While epoxy is a superior adhesive material, it has some drawbacks:

UV Sensitivity: Epoxy can yellow when exposed to moisture and UV light. Therefore, it is crucial to choose parts with UV-protected epoxy hardeners. Brands like Scopione use epoxy resins with added UV protection to prevent discoloration and maintain the parts’ appearance and performance.

Amine Blush: A wax-like residue that forms during the curing process, which must be removed before additional layers can be applied.


Vinylester Resin

Vinylester resin is less expensive and about one-third as strong as epoxy. It does not bond as effectively to carbon fiber or Kevlar but has specific aesthetic and practical uses. Common characteristics of vinylester resin include:

  • Limited Adhesion: Vinylester resin adheres better to fiberglass than to carbon fiber or Kevlar.
  • Cosmetic Enhancements: Often used as a surface coating to enhance the appearance of carbon fiber parts.

Due to its moderate strength and aesthetic appeal, vinylester is primarily used for products where appearance is prioritized over structural integrity.


Polyester Resin

Polyester resin is the least expensive option and bonds poorly with carbon fiber and Kevlar. It is primarily compatible with fiberglass. Key points about polyester resin include:

  • Low Bonding Strength: Polyester resin offers weak adhesion to carbon fiber and Kevlar.
  • Cost-Effectiveness: While inexpensive, it is unsuitable for applications requiring high strength or durability.

Unless cost is the sole consideration and strength is not critical, polyester resin-based carbon fiber or Kevlar parts are generally not recommended for automotive applications.

Choosing the right resin for carbon fiber parts depends on your performance, durability, and budget requirements. Epoxy resin provides the highest strength, durability, and resistance to environmental factors but comes at a premium price. Vinylester offers aesthetic benefits but lacks the strength needed for high-performance use. Polyester resin, though affordable, is best suited for fiberglass-based applications and should be avoided for critical carbon fiber components.

By understanding the strengths and weaknesses of each resin type, you can make an informed decision and invest in carbon fiber parts that meet your vehicle’s needs and your performance expectations.

    • Advantages: Balances reflectivity and scratch resistance; provides a refined look without the high reflectivity of gloss.
  4. Textured Finish (Peel-Ply)
    • Appearance: Rough, sandpaper-like texture.
    • Advantages: Ideal for bonding applications; the texture promotes better adhesion with adhesives or additional layers.
  5. Forged Carbon Finish
    • Appearance: Unique, marbled pattern resulting from randomly arranged carbon fiber fragments.
    • Advantages: Distinctive aesthetic; often used in luxury or high-end applications to stand out from traditional carbon fiber weaves.
  6. Clearcoat Finish
    • Appearance: Transparent coating that can be glossy or matte, enhancing the underlying carbon fiber appearance.
    • Advantages: Provides UV protection; adds an extra layer of durability; enhances visual depth.
  7. Sanded Finish
    • Appearance: Smooth, matte-like surface achieved by sanding the outer resin layer.
    • Advantages: Removes surface imperfections; prepares the component for painting or additional coatings.
  8. Painted Finish
    • Appearance: Opaque color applied over the carbon fiber, hiding the weave pattern.
    • Advantages: Offers customization in color; provides additional environmental protection; commonly used in applications like sporting goods.

Selecting the appropriate surface treatment and finish depends on the intended application, desired aesthetics, and environmental exposure of the carbon fiber component.

Care and Maintenance of Carbon Fiber Parts

Proper care and maintenance of carbon fiber automotive parts are essential to preserve their appearance, structural integrity, and longevity. Here’s an expanded guide to help you maintain your carbon fiber components effectively:

1. Regular Cleaning

  • Gentle Washing: Use a mild automotive-specific cleaner or pH-neutral soap with a soft microfiber cloth to clean carbon fiber surfaces. Avoid harsh chemicals, as they can damage the clear coat protecting the carbon fiber.
  • Avoid Abrasive Materials: Steer clear of abrasive brushes or rough sponges that could scratch the surface. Instead, opt for soft-bristled brushes or microfiber towels to gently remove dirt and grime.

2. Protection from UV Exposure

  • UV-Resistant Coatings: Apply a high-quality wax or ceramic coating that offers UV protection to shield the carbon fiber from sun damage. Regular application helps maintain the glossy finish and prevents oxidation.
  • Parking Considerations: Whenever possible, park your vehicle in shaded areas or use a car cover to minimize direct sunlight exposure, reducing the risk of UV-induced fading or discoloration.

3. Inspection and Damage Prevention

  • Regular Inspections: Periodically examine carbon fiber parts for signs of damage, such as cracks, chips, or delamination. Early detection allows for timely repairs, preventing further deterioration.
  • Avoid Chemical Exposure: Keep carbon fiber components away from harsh chemicals like gasoline, brake fluid, or solvents, as they can corrode or damage the surface. In case of accidental exposure, clean the area immediately with a mild soap and water solution.

4. Polishing and Restoration

  • Addressing Oxidation: If the carbon fiber surface becomes oxidized or yellowed, use a fine-grade polish with a soft polishing pad to restore clarity and shine. For heavily oxidized surfaces, professional restoration may be necessary.
  • Protective Coatings: After polishing, apply a protective sealant or ceramic coating to enhance the surface’s resistance to environmental factors and maintain its luster.

5. Maintenance Best Practices

  • Avoid High-Pressure Washing: Refrain from using high-pressure water jets directly on carbon fiber parts, as they can cause delamination or force water into areas that may lead to damage. Instead, use a gentle stream of water during cleaning.
  • Temperature Considerations: Protect carbon fiber components from extreme temperatures, as excessive heat can affect the resin matrix, leading to potential structural issues. Avoid parking near heat sources or exposing the vehicle to extreme cold without adequate protection.

By following these guidelines, you can ensure that your carbon fiber automotive parts remain in excellent condition, enhancing both the aesthetic appeal and performance of your vehicle.
