碳纤维混杂织物增强SiC陶瓷基复合材料的层间剪切力学性能研究
Interlayer Interfacial Shear Mechanical Properties of SiC Ceramic Matrix Composites Reinforced With Hybrid Carbon-fiber Fabrics
摘要
Abstract
This work investigated the influence of hybrid design based on unidirectional and two-dimensional woven fabrics on the interfacial properties of SiC-ceramic matrix composites.By using the short beam shear test,effects of volume fraction,ply angle and lay-up ratio of unidirectional(UD)laminates on the interfacial shear strength(IFSS)were identified.The results show that the IFSS of hybrid composites is larger than that of pure satin fabric reinforced composites.As for the hybrid design of UD and satin laminates,there is an increasing trend of the equivalent IFSS as the content of 0°ply in hybrid composites increases.When the total volume fraction of UD laminates is fixed,a greater lay-up ratio of 0°plies enhances the equivalent IFSS of hybrid composites,while increasing the lay-up ratio of±45° and+90° plies reduces the equivalent IFSS and affects the location of crack initiation.关键词
