Traditional steel manufacturing is carbon-intensive. The new FRP process operates at significantly lower temperatures and requires less energy. Crucially, because the material is a thermoplastic composite, end-of-life recycling is viable. At the end of the car’s life, the composite can be shredded and repurposed into new automotive parts or consumer goods, supporting a true circular economy—something the current metal-heavy automotive industry struggles to achieve.
The Fraunhofer IMWS InThElekt project offers perhaps the clearest vision of how FRP will transform EV design at the systems level. By developing integral structural vehicle components based on thermoplastic sandwich composites with embedded electronics, the project aims to eliminate the traditional separation between mechanical structure and electrical functionality.

Specialized resin matrices can be infused with conductive fibers to achieve electromagnetic interference (EMI) shielding, protecting the vehicle’s low-voltage control systems. 2. Structural Chassis Components and Crush Zones
GFRP formulations act as natural thermal barriers, slowing down heat transfer compared to highly conductive aluminum.
FRP naturally resists heat transfer. This helps isolate thermal runaway events and keeps the battery within its optimal operating temperature.
