Nowadays, the automotive industry has a critical challenge to meet the goals of crashworthiness as well as sustainability. While carbon fiber reinforced polymers (CFRPs) provide excellent specific strength and energy absorption for crash absorber applications, conventional thermoset epoxy resins cannot be recycled. This limitation contradicts the EU End-of-Life Vehicle regulations that necessitate 95% recovery of the vehicle’s mass. Additionally, the lack of standardized testing methods to evaluate the crashworthiness of composite materials obstructs the proper selection and certification for automotive use. This thesis investigates whether ELIUM^(® ) (developed by Arkema), a fully recyclable thermoplastic poly-methyl methacrylate (PMMA) resin, can replace traditional epoxies in automotive crash absorber systems without sacrificing crashworthiness performance and safety aspects of the occupants.
