Characterization of the Mechanical and Fatigue Behavior of Braided Composites Made of Twisted Yarns

Abstract:

In this study an experimental investigation was undertaken to characterize the influence of twisted yarns on the mechanical and fatigue behavior of 2D braided composites with a braiding angle of ±45°. Rectangular specimen made of untwisted and twisted carbon yarns are tested in the braiding (±45° fiber orientation) and in the yarn direction (0/90° fiber orientation). Experimental results will include modulus and strength values based on tensile and compression tests for both test directions. In addition, the effect of fiber twisting on S/N-curves are discussed.
