Abstract:

A novel experimental test method is presented to assess the tensile properties of single fibers, which pairs a Psylotech Nano-test system small-scale test frame with a Keyence 3-D laser scanning confocal microscope. This enables in situ optical microscopy to obtain fiber diameter measurements for each tensile experiment and thus improves the accuracy of calculated tensile properties. In this work, the developed test method is used to determine the tensile material properties for 4 types of Kevlar fiber. Results are presented and trends associated with fiber diameter are discussed.
