Cyclic Load and Residual Flexure Strength of Plain Weave Carbon/Epoxy Composite – An Experimental Verification

P. K. Dash, Ankita Dash

Abstract :

The growing use of plane–weave carbon fiber reinforced composite in aerospace components design demanded to support and define the engineering concepts of durability and damage tolerance. After fatigue damage, the reliability information in terms of flexure strength investigated in this paper. A series of three point flexure tests conducted over the range of cyclic damaged specimens. The experimental results analyzed with reference to residue strength and reduced stiffness of the CFRC specimens. Fatigue damage followed by flexure tests produced significant strength reduction in comparison to simple flexure tests, and the reduction in residual flexural strengths and stiffness purelydepended on the magnitude of fatigue stress applied with number of cycles subjected to bi–directional woven carbon/epoxy composite specimens.
