Abstract

The use of advanced fibers in applications where they are subjected to extremely energetic events has necessitated the need to develop measurement tools that quantify their properties at high strain rates (HSR). The split Hopkinson tension bar (SHTB) has been shown to be suitable for obtaining single fiber HSR data. However, the fiber gluing approach limits the testing rate to two or less fibers per day. In this paper the SHTB is modified to permit the direct gripping of fibers, thereby increasing sample throughput. Statistical analyses of the data indicate (1) that measurement repeatability of tests using the direct grip approach is better than those using the gluing method and (2) the short fiber failure statistics of the method are consistent with the behavior expected as the gauge length decreases.
