Abstract

Preliminary data for testing fibers at high strain rates using the Kolsky bar test by Ming Cheng et al. [1] indicate minimal effect of strain rate on the tensile stress-strain behavior of poly (p-phenylene terephathalamide) fibers. However, technical issues associated with specimen preparation appear to limit the number of samples that can be tested in a reasonable time. In addition, under the Kolsky bar testing condition fiber fracture may occur at the interface between the fiber and adhesive rather than in the gage section. In this study, the authors investigate the effects of different gripping methods in order to establish a reliable, reproducible, and accurate Kolsky bar test methodology for single fiber tensile testing. As many single fiber tests have been carried out associated with ballistic research, we compare the Kolsky bar test results with the quasi-static test results to determine the tensile behavior over a wide range of strain rates.
