Abstract:

In directing the research effort for improving the compressive 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. Keywords Polymer fibers Direct compression testing PBO Kevlar 29 Kevlar 49 TM Fiber compression strength.
