The objective of this research is to investigate the crack behavior in five harness satin woven carbon fiber reinforced polymer (CFRP) composite laminates with temperature-dependent material properties under tension at cryogenic temperatures. A situation of generalized plane strain is considered, and cracks are assumed to have occurred in the transverse fiber bundles. Also, both cases where the tips of the cracks are located in the fiber bundles or at the interfaces between two fiber bundles are treated, and a finite element technique utilizing special singular elements is used to obtain the stress intensity factors at the tips of the transverse cracks in two-layer woven CFRP laminates. The numerical results are then discussed in detail.
