Simulation Prediction of Crashworthiness Feature of Advanced Composites

Abstract

Abstract. Based on the research of crashworthiness of advanced composites, PAM-Crash simulation software was utilized to predict the crash behavior of thermoset matrix and thermoplastic matrix. The simulation results demonstrated that the thermoset matrix and thermoplastic matrix showed an ideal fragment collapse mode, with a SEA of 63.3 kJ/kg and 50.9 kJ/kg, respectively. Both the SEA values are higher than Aluminum alloy, 17.32 kJ/kg, which means both material systems are promising to replace metal as energy absorption structure in transport applications.
