Compressive Properties of High Performance Polymeric Fibers

Abstract

In directing the research effort for improving the compr essive properties of rigid rod polymeric composite fibers, a reliable testing technique for determining compressive properties is needed. The technique developed used the Tecam Micro-Tensile Testing Machine, MTM-8 and allowed direct tension and compression testing of composite fibers of extremely short gage length. The measured data was analyzed for corrections in machine compliance and possible errors in gage length misreading, fiber slippage, glue deformation, fiber misalignment, and nonuniform stress distribution. A non polymeric fiber was tested to determine if any fiber material dependence existed. The data was compared to the compressive properties obtained from the elastica loop, bending beam, recoil, and composite tests. This was the only known research of high performance polymer fibers in direct tension and compression testing which allowed the construction of a full stress-strain curve. Keywords: Polymer fibers, Direct compression testing, Theses.
