Investigation of Strain-rate Effects in Self-reinforced Polypropylene Composites

The strain-rate sensitivity of a hot-compacted formed self-reinforced thermoplastic composite, based on polypropylene fibers in a polypropylene matrix, was investigated through a series of quasi-static and dynamic tensile tests. Characterization of the mechanical property dependence on strain-rate for a self-reinforced thermoplastic is an important issue when the material forms one part of a hybrid system, as in the case of a thermoplastic...
