摘要
The tensile behavior of a unique 2.5 D C/SiC composite and associated damage evolution was characterized by means of acoustic emission (AE) technique. The results show that the stress-strain curves exhibit mostly nonlinear behavior, which corresponds well with the AE activities. All the evolutions of damage characteristics indicate the phenomenon of matrix cracking saturation which is in agreement with AE results. Microstructural observations reveal extensive matrix cracks and the fracture of yarns always occurred in yarn crossover areas due to the unique weave architecture.
