Tensile Properties of Carbon Fiber Triaxial Woven Fabric Composites

Abstract

Triaxial woven fabrics are attractive for industrial applications as a rein forcement of composite materials. In this article, tensile properties and fracture behaviors of carbon fiber triaxial woven fabric composites were discussed by comparing with biaxial woven fabric composites. Moreover, the effect of weave structure on the tensile properties of the triaxial woven fabric composites was investigated. Triaxial woven fabric composites were isotropic in modulus, and anisotropic in strength. Tensile properties of basic woven fabric composites were superior compared to the Bi-Plain and biaxial woven fabric com posites. The fracture mechanisms of triaxial woven fabric composites varied with fiber ori entation. This was observed from experimental data of AE (acoustic emission) mea surement and numerical analysis. © 1993, Sage Publications. All rights reserved.
