TENSILE BEHAVIOR OF A QUASI-ISOTROPIC CARBON-CARBON COMPOSITE

This paper reports an analytical and experimental investigation of the tensile behavior of a two-dimensional woven carbon-carbon composite w ith a quasi-isotropic stacking sequence. Specimens in their as-receive d condition were already saturated with transverse cracks due to therm al stress induced during fabrication. Further cracking under load was not detected. The completely unloaded specimen showed that the slight residual strain tended to increase with applied tensile strain. Damage progression as seen on specimen edges and elastic moduli degradation were recorded. The predicted Young's moduli were in good agreement wit h the measured data.
