Passenger car


In the automotive industry's journey toward electrification and carbon neutrality, "lightweighting" is no longer just a technical option—it is an essential pathway to extending range, optimizing handling, and ensuring safety. As a revolutionary alternative to traditional metals, Continuous Glass Fiber Reinforced Thermoplastic Composites (CFRT) are emerging as a star material in next-generation passenger vehicle manufacturing, thanks to their exceptional specific strength, immense design freedom, and inherent eco-friendly recyclability.

Core Application Scenarios: From E-Powertrains to Chassis & Body

Currently, the application of these composites in passenger vehicles has moved from conceptual exploration to full-scale mass production, shining particularly brightly in the core components of new energy vehicles:


Such as Battery Pack Enclosures & Protection Systems


Electric vehicle battery packs account for a significant portion of the vehicle's weight and demand extremely high safety standards. Battery top covers and underbody shields (skid plates) made from continuous glass fiber reinforced thermoplastics can achieve significant weight reductions of 40%-65%, while providing excellent impact resistance, humidity/heat tolerance, and electromagnetic shielding.
  • Tech Highlight: Through secondary integrated molding processes combining compression molding and overmolding, complex sealing surfaces, mounting structures, and stiffening ribs can be seamlessly integrated. This intrinsic sealing design eliminates leakage risks associated with welding, effectively prevents thermal runaway propagation, and safeguards battery safety.

Beyond its deep integration into battery underbody shields and core e-powertrain components, Continuous Glass Fiber Reinforced Thermoplastic Composites are also expanding into body panels such as trunk and frunk (front trunk) lids. With their exceptional lightweight properties and superior specific strength, these advanced materials not only optimize the vehicle's overall weight distribution but also effortlessly meet the rigorous demands of high-performance models for dynamic response and structural rigidity.

Green Cycle: The Perfect Partner for Sustainable Mobility

Beyond the leap in performance, the greatest allure of continuous glass fiber reinforced thermoplastic composites lies in their eco-friendly attributes throughout the entire lifecycle. With increasingly stringent global environmental policies—such as the EU's New Battery Law—the recyclability of thermoplastic composites has become a powerful tool for automakers striving to achieve carbon neutrality goals.
Unlike difficult-to-recycle thermoset materials, discarded CFRTP parts can be crushed, melted, and re-granulated to be directly reused as raw material in automotive interiors or other industrial sectors. This truly realizes a green "cradle-to-cradle" closed loop, drastically reducing the carbon footprint.

Looking Ahead  

With the continuous optimization of material formulations and the maturity of automated production processes, the cost of Continuous Glass Fiber Reinforced Thermoplastic Composites is gradually decreasing, and their application scenarios are set to expand further. From luxury sports cars to mainstream family sedans, this material—combining high strength, lightweight properties, and excellent cost-performance—will serve as the solid cornerstone for building the future of green, intelligent, and safe automobiles.
