Characterizing the strain rate sensitivity of the tensile mechanical properties of a thermoplastic composite

Thermoplastic composites (TPCs) are being given increased consideration for application in vehicle front-end structural crash components. However, studies on the high strainrate behavior of TPCs have been relatively limited. In this study, the effect of strain rate on the tensile properties of a woven fabric commingled E-glass/polypropylene thermoplastic composite was investigated over a strain-rate range of 10−4 to 70 s−1. Quasi-static tests...
