Title: Effects of fiber gripping methods on single fiber tensile test using Kolsky bar
Published: June 10, 2010
Abstract: Preliminary data by Ming Cheng et al. indicate minimal impact of strain rate on the tensile stress-strain behavior of Kevlar. However, technical issues associated with specimen preparation appear to limit the number of samples and show an undesirable fracture location at the interface between the fiber and adhesive. 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.
