Residual stress distribution around the woven fiber bundles was analyzed by a Finite Element Method to understand the fracture behavior of the laminated Si-Ti-C-O fabrics (10vol%)/mullite matrix composite under anticlastic bending test. The analysis revealed that the residual stress was concentrated on the fabric node, a cross point of the longitudinal and horizontal fiber bundles. The result could explain the formation of surface cracks in the mullite layer during anticlastic bending test, which originated from the fabric node. We have conducted the anticlastic bending test on 0°/90° crossply laminate composites of the Si-Ti-C-O fibers (10vol%)/mullite system to evaluate the influence of fabric node on the fracture behavior. No surface crack was formed in the crossply laminate composites with no fabric node. The fracture strength of the crossply laminate composite was twice that of the layered composite with woven fabric. In other words, the fabric node of the fiber bundles greatly affects the mechanical reliability of layered composites.
