As global automakers accelerate efforts toward electrification and vehicle lightweighting, carbon fiber composites are increasingly being adopted in structural and aesthetic automotive applications. HRC (Jiangshu, China) says it is meeting this demand through a combination of advanced materials development (including the use of thermoplastic composites), efficient manufacturing technologies and closed-loop recycling systems.

HRC’s operations span across five countries. Vertically integrated capabilities — R&D, engineering and design, serial production, and recycling and reuse — supports OEMs across the entire composites life cycle, enabling scalable and sustainable solutions for next-generation mobility platforms.

Hybrid carbon fiber monocoque for structural lightweighting

Exclusively developed and manufactured by HRC, the hybrid monocoque is one example of the company’s automotive composites proficiency. It achieves a 30% weight reduction compared to conventional steel-aluminum body structures, with a reported lightweight coefficient of 0.95. To meet structural performance targets, the monocoque incorporates more than a dozen advanced joining technologies, including the use of PMI inserts at critical zones to ensure enhanced handling stability and crash safety performance under extreme working conditions, balancing the triple technical goals of lightweight, safety and driving pleasure.

According to HRC, as the largest carbon fiber monocoque in series production, the hybrid structure creates a new precedent for the use of carbon fiber as a primary structural material in high-end mass production models in automotive. 

Thermoplastic composite parts for high-volume applications

Thermoplastic composite (TPC) processing is a method with significant potential for mass production HRC reports, offering advantages in efficiency, cost-effectiveness and sustainability. Ideal for mass-producing large structural components like door panels and power battery pack shells, this process features short molding cycle times, recyclability and optimal impact resistance.

HRC’s TPC door module exemplifies the application of this technology in mass-production programs. The component uses a combined compression and injection molding process, eliminating the need for secondary gluing operations typical of traditional composites fabrication.

The process is fully automated, ensuring high levels of product consistency, dimensional stability and production efficiency. By integrating structural functionality and decorative surfaces into a single forming cycle, the solution supports reduced part count and assembly complexity.

This approach not only improves throughput and repeatability but also aligns with circular economy objectives, as the materials can be reprocessed at end of life — supporting OEMs in meeting sustainability and lightweighting targets simultaneously.

Surface-grade performance components

Beyond structural components, HRC is exploring design-driven uses of carbon fiber. In applications where structural performance meets aesthetic demands, HRC develops carbon fiber components that combine mechanical function with distinctive visual appeal.

The full carbon fiber wheel hub, for example, reduces mass by more than 40% compared to conventional metal wheels, effectively lowering the load on the vehicle’s suspension system and improving both handling and acceleration.

The rear bumper lower trim assembly, fully designed with aerodynamic principles, combines track-level performance with a distinctive visual identity. The component features sharp, tall and streamlined diffuser fins on the left and right lower bumper fins, paired with distinctive carbon fabric textures makes the product stands out dynamically or when stationary.

The aerodynamic winglet structures are defined by thin, towering cross-sections and sharp contours, engineered to contribute both to aerodynamic efficiency and styling. The exposed carbon fiber weave pattern delivers high-performance character of the part, giving it a strong visual impact.

Recycled composites, closed-loop systems

HRC also emphasizes its implementation of a closed-loop system covering development, industrial application, recycling and reuse of composite materials. It uses its patented microwave pyrolysis technology to transform carbon fiber wasted into recycled carbon fiber (rCF). Through advanced thermoplastic processes, this material is then turned into cost-effective and eco-friendly automotive components (learn more about the closed-loop system here).

The final rCF thermoplastic automotive parts demonstrates HRC’s “waste-to-product” green manufacturing business model and proves the compatibility of high-end composites with circular economy principles.

As the automotive industry navigates rapid transitions in electrification, sustainability and smart manufacturing, lightweighting remains central to improving vehicle range, performance and safety. HRC continues to invest in material innovation, scalable manufacturing and sustainable systems —enabling OEMs to meet evolving performance requirements without compromise.
