Study on the Failure Analysis Method of the Woven Composite Based on the Micro-Structural Character

Abstract:

Based on the micro-structure, a mosaic model was established to obtain the stresses distribution of the C/C composite beam subjected to bending load. Then a subroutine for failure analysis was introduced to calculate the failure index of the composite beam. A corresponding laminate model was used to validate the calculation of the mosaic model. The results indicated that the method combining micro stresses and macro failure criterion was suitable for strength analysis of composite structure, which could be used in guiding the design of composite.
