摘　　要：提出一种对叠经多层间隔结构整体机织复合材料的改进方法,该结构复合材料采用增强体嵌入的方式对材料强度进行改进,增加了中空复合材料强度的可设计性。对嵌入用的增强体材料、非嵌入的多层整体机织中空复合材料和嵌入后的多层整体机织中空复合材料分别进行了抗压力学性能测试。在平压和侧压力学测试实验中,嵌入式机织复合材料的力学性能均好于非嵌入机织复合材料,而在平压测试实验中,得到了嵌入式机织复合材料预制体与树脂的共同增强系数为1.40,证明该嵌入式机织复合材料结构设计的合理性。此外得出3种材料侧压的力学性能也均好于平压。An improved method of a kind of multi layer embedded enhancing integrated woven preform is pre sented. This structure uses embedded enhancing method which provides more freedom for the intensity of the hollow spacing material in design. An experiment of the compressive performance for the multi-layer integrated woven com- posite, multi layer embedded enhancing integrated woven composite and the embedded materials is conducted. The re- sults indicate that the mechanical property of the embedded woven composites is better than the woven composites, and the enhanced coefficient of the plain pressing embedded woven preform and the resin reaches 1.40 which proves the rationality of the structural design. Besides, the side-pressing mechanical capability of the three materials is better than the plain pressing.
