  • 521 Evaluations of Strength and Stiffness of C/C Composites under high temperature oxidation conditions

抄録

Oxidation tests under loading were carried out to clarify the effect of loading on the oxidation mechanism. And tensile tests were carried out under various conditions to understand the degradation of stiffness and strength. To predict the stiffness degradation, the analytical model based on both Shear-Lag Model and Diffusion Model was proposed. Analytical prediction was compared to experimental results to estimate the effectiveness of proposed model.
