The document discusses the use of fiber-reinforced plastic composites made from sustainable materials for automotive applications. Specifically, it examines glass fiber reinforced with furan resin (BioCompA) and flax fiber reinforced with furan resin (BioCompB), comparing them to a standard glass fiber/polyester composite. Testing included fluid exposure, tensile strength, fastener pull-through, and impact resistance. Results showed BioCompA performed similarly to glass fiber/polyester composite, while further development is needed for BioCompB to improve mechanical properties and reduce resin bleeding.
