Tensile Test and Analysis of the Geometry of Kevlar/Epoxy Composites

Abstract:

This paper is concerned with the analysis of geometric composites, whose reinforcement was made of plain weave fabric with different geometries. They were determined following the basic parameters of the textiles e.g. crimp length, crimp amplitude, thickness of the woven fabric, dimensions of the cross-sectional tow (tow width, tow height) and crimp angle. The number of fibers in the warp and tow strands and number of layers in the composites were also determined. These composites comprised of the same materials were subjected to a standard tensile test, according to DIN EN ISO 14 129. The mechanical properties of the composite as a whole were determined by tensile test.
