Carbon Fiber Automotive Components: Interior, Exterior and Exhaust

This page is a component-level breakdown of carbon fiber parts for road and race cars — interior trim, body panels, diffusers, mirror housings and exhaust heat shields. Our automotive applications guide covers the material science and the business case; this page is about the individual parts, the tooling behind them, and the finish options (gloss, matte, forged) that customers ask for most. Whether you need a single prototype panel or a repeatable production run, the process is the same: lay-up schedule first, tool second, parts third.

Carbon fiber automotive supplies are automotive-related products made mainly of carbon fiber. The following is a detailed introduction to them:

Material properties: Carbon fiber combines the inherent hardness of carbon materials with the soft processing characteristics of textile fibers. It features high strength, lightweight, high rigidity, high wear resistance, high temperature resistance, corrosion resistance, and electrical insulation. Therefore, it is hailed as the “King of Materials”.

The manufacturing process is rather complex, involving multiple procedures such as drawing, stabilization, carbonization, and graphitization. After that, it can be woven into fabric and then processed through interlaced stacking, epoxy resin bonding, high-temperature and high-pressure treatment, and other procedures to produce various carbon fiber automotive products.

Common products and advantages

Vehicle body components: such as the body, chassis, roof, etc. Compared with traditional materials, all-carbon fiber structural components can reduce weight by 20% to 40% and increase strength by 20% to 60%. This can significantly enhance the vehicle’s handling, acceleration performance and fuel efficiency, while strengthening the body rigidity and improving safety.

Exterior accessories: Carbon fiber exterior accessories such as the rear wing, front diffuser, and rear spoiler can improve the vehicle’s aerodynamic performance, reduce air resistance at high speeds, increase ground adhesion, and enhance driving stability. For instance, the carbon fiber rear wing of Aikexun adopts an irregular-shaped air bag combined with an autoclave forming process, featuring a hollow internal structure. It is lightweight, has low wind resistance, and can also enhance handling stability.

Interior components: The center console, decorative strips, instrument panel and other interior components are made of carbon fiber, which can reduce weight. Its unique texture and feel can also enhance the design sense, luxury and sporty atmosphere of the interior.

Chassis components: Carbon fiber stabilizer bars, connecting rods, springs and other chassis components have a significant weight reduction effect and strong durability. For instance, compared with steel springs, the carbon fiber springs of Aikexun are 70% lighter, which can reduce vibration transmission, improve driving characteristics and enhance the comfort inside the vehicle.

Braking system: Carbon fiber brake discs have excellent high-temperature resistance, which can ensure the stability of braking performance under high-intensity use, effectively enhance braking effect and reduce braking distance.

Other components: Carbon fiber is also applied in drive shafts, intake systems, engines and other parts, which can improve intake efficiency, withstand high temperatures and maintain stable performance. In addition, components such as carbon fiber rearview mirror housings, seat frames, and car luggage can not only meet functional requirements but also enhance the overall quality of the vehicle.

Current market application status: Carbon fiber automotive products were initially mainly applied in high-end fields such as aircraft, rockets, and bulletproof vehicles, as well as in F1 racing events. Nowadays, with the development of technology and the gradual reduction of costs, its application in civilian vehicles is becoming increasingly widespread. Not only luxury cars, but also some ordinary models have begun to adopt carbon fiber accessories as optional configurations.

The problems faced in development: First, the price is relatively high, with high processing costs, making it difficult to achieve large-scale mass production; Second, there is a lack of experience and personnel in composite material design. Automotive enterprises have insufficient R&D talents in this area, and relevant design data and standards are also incomplete. Thirdly, major domestic automakers are adopting a wait-and-see attitude towards the application of carbon fiber. They are not very familiar with the processing techniques, which poses a relatively high investment risk and may also affect the investment in existing production lines.

Finish options — gloss, satin, matte and forged — are applied after molding and inspection. Surface finish is chosen per part: a visible exterior panel and a structural underbody component have very different priorities.
