Mechanical behavior of glass-fiber reinforced thermoplastic materials under high strain rates

Glass-fiber reinforced polypropylene (PP) and polybutene-1 (PB-1) materials were investigated in a high-speed tensile test. The glass-fiber content of the materials and the strain rate were varied in the range between 0 and 40 wt.-% and 0.007 and 174 s−1, respectively. The aim of the investigations was to show in which way the glass-fiber content, and especially the strain rate, influence the material behavior, in this case the stress–strain...
