FRP is utilized in crossmembers, floor panels, and suspension components like leaf springs. Replacing metal components reduces the vehicle's unsprung mass, resulting in smoother handling, sharper steering response, and less wear on electric drivetrains. 3. Body-in-White (BiW) and Exterior Panels
Lightweight chassis parts, such as CFRP monocoques, reduce weight and improve handling. FRP composites are increasingly used for roofs, doors, and fenders, contributing to both aesthetics and structural strength. C. Electric Motor and Power Electronics Components
The electric vehicle (EV) industry is undergoing a massive shift. As automakers push for longer ranges, better efficiency, and enhanced safety, traditional materials like steel and aluminum are reaching their physical limits.

The battery pack is the most expensive and heaviest component of an EV. Traditional steel enclosures are heavy and prone to corrosion. Aluminum is lighter but expensive to cast and offers poor thermal insulation. FRP is utilized in crossmembers, floor panels, and
To make FRP viable for mass-market automotive production, manufacturing workflows have evolved from slow, manual processes to high-speed, automated systems. Resin Transfer Molding (RTM) and High-Pressure RTM (HP-RTM)
EV motors spin at up to 20,000 RPM, creating high-frequency vibrations. Metal mounts can transmit these vibrations as noise, vibration, and harshness (NVH). Electric Motor and Power Electronics Components The electric
The battery pack is the single heaviest component in any EV. Its enclosure must be robust, safe, and as light as possible. FRP has proven to be the ideal solution. For example, long glass-fiber reinforced polypropylene (PP) resins like SABIC's STAMAX™ series provide an impact-resistant, flame-retardant, and lightweight alternative to metal-intensive solutions, achieving a 30-40% mass reduction. Composite battery enclosures typically achieve approximately 30 to 40% mass reduction versus aluminum, with potential savings approaching 50% versus steel. Furthermore, carbon fiber-reinforced polymer (CFRP) battery enclosures provide exceptional rigidity and safety. A notable example is the collaboration between SGL Carbon and NIO, which produced a CFRP battery enclosure that is around 40% lighter than comparable aluminum solutions. Composite enclosures also offer superior thermal management, better protecting the battery against both cold and heat.
Fiber-Reinforced Polymer (FRP) is a composite material consisting of a polymer matrix reinforced with high-strength fibers. In electric vehicle (EV) manufacturing, the polymer is typically an epoxy, polyurethane, or vinyl ester resin, while the fibers are usually carbon, glass, or aramid.
