Tensile and Compressive Failure Behaviors of Triaxially Braided Composite

ZHENQIANG ZHAO, CHAO ZHANG, YULONG LI

Abstract


The failure mechanisms of triaxially braided composite under in-plane tensile and compression loads are investigated in this study. The testing specimens are cut from a typical 8-layer 0°/±60° triaxially braided composite panel which is fabricated with Toray T700 carbon fiber and a toughened epoxy resin 3266. The quasi-static tension and compression loads that parallel or vertical to the 0° fibers are applied by using a Hydraulic testing machine, respectively. The Digital Image Correlation (DIC) technology is implemented to measure the displacement and strain fields of gauge section for both the tensile and compression tests. As a result, the failure mechanisms under different load conditions are elaborated contrastively.
