摘要

The tensile and compressive tests of glass-epoxy composites with 1-200s~-1 strain rates which are typical strain rate range during automobile crash accidents were performed in order to measure the strength variation with respect to stain rate. The tests were performed using both a horizontal type pneumatic impact tester and a conventional dynamic universal test machine with strain-rate- increase mechanisms.
