Effects of High Temperature on Tensile and Bending Strengths of T300 Carbon Fiber Three Dimensional Braided Composites

Abstract:

In this paper, the tensile and bending strengths of T-300 carbon fiber three dimensional braided/epoxy resin composites at 23 oC and 150 oC were researched. The results indicate that the effect of temperature on the tensile strength and bending strength of three dimensional braided composites is sentitive. However high temperature makes bending strength of 3D braided composites lost more than that of tensile strength of 3D braided composites. The average tensile strength of 3D braided composites at 150 oC is 65.06% of average tensile strength of 3D braided composites at 23 oC. The average bending strength of 3D braided composites at 150 oC is only 11.44% of average bending strength of 3D braided composites at 23 oC. This means that application temperature should be taken into account when 3D braided composites are used.
