Abstract:

Aiming at the failure of ceramic matrix composites upon tensile and bending loading during service, the three-dimensional six-directional braided SiCf/SiC composites were investigated, and the mechanism of the mechanical properties of the composites and the relationship between the fiber and structure during the stress process was analyzed. Microcomputer tomography technology was used to obtain three-dimensional images of the material structure and pores, and the longitudinal and transverse tensile/bending properties of the composite material were tested, and the damage mechanism was discussed. The results show that the three-dimensional six-directional braided SiCf/SiC composites exhibit obvious anisotropic characteristics, and the longitudinal tensile and bending strength is 10.37 and 5.06 times that in the transverse direction, respectively. The damage modes of the composites under different forces were found to be different. Under tensile loading, the longitudinal cracks expand along a zigzag route formed by the six-direction yarns, while the transverse cracks expand along the braid axis, resulting in tensile failure. Under bending loading, the cracks expand along the thickness direction and finally cause the ductile fracture in the longitudinal and transverse directions, and the longitudinal toughness was found better than the transverse toughness.
