摘要：

A high strain rate compression test with a constant speed of 1.5 m/s has been performed on samples of negative Poisson's ratio and normal open-cell polyurethane foam. The tests show that the transformation of the normal foam into the auxetic phase greatly increases the crashworthiness qualities of the open-cell foam.
