We considered the free-edge and interlaminar stress states of G-10CR woven glass-epoxy laminates under uniform axial extension with temperature-dependent properties. The damage, in general, occurred in the interior of G-10CR glass-epoxy laminates. A finite element method was used to study the influence of weave geometry and cryogenic temperatures on the edge and interlaminar stresses of two-layer woven laminates under uniform axial strain. Numerical calculations are carried out and the stress distributions along the free edge and midplane of the woven laminates are shown graphically for various values of the temperature Φ and warp angle θ. The stress distributions of woven and nonwoven laminates are also compared. Finite element results demonstrated that the weave geometry reduced edge stresses, and the tendency was more pronounced with increasing θ. The large debonding stress tended to increase with increasing θ and decreasing Φ.
