Abstract

The Kolsky bar test has been widely used in measuring material behavior under high strain rate conditions. In particular, this methodology has been used to characterize the high strain rate behavior of polymer and polymer composites during ballistic impact. Chen et al. measured the tensile properties of single PPTA fibers at high strain rates by gluing the fiber directly to the Kolsky bar. However, the application of this technique is somewhat limited due to the time-consuming nature of the gluing procedure [1]. Due to the highly stochastic nature of fiber tensile strength, large test sample sizes are required to analyze distributions of fiber properties such as tensile strength, modulus and strain-to-failure. The current authors have investigated an alternative gripping method to conduct high throughput single fiber tensile test at high strain rates. As an extension of these efforts, a softer rubber is being considered as an alternative fiber gripping material to the harder PMMA, in order to minimize stress concentration in the gripping area. In preliminary tests using a PMMA grip, the system compliance obtained by the 5 mm, 10 mm and 60 mm gauge lengths was determined for the tensile tests
