This paper reports an analytical and experimental investigation of the tensile behavior of a two‐dimensional woven carbon‐carbon composite with a quasi‐isotropic stacking sequence. Specimens in their as‐received condition were already saturated with transverse cracks due to thermal 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 with the measured data.
