|
Abstract:
根据多级结构设计思想，把高性能聚甲基丙烯酰亚胺（PMI）泡沫加入到单向碳纤维增强树脂复合材料之间，制备多级复合材料蜂窝结构。对多级复合材料蜂窝结构的平压性能进行了研究，包括多级复合材料蜂窝结构平压性能的理论预报和试验验证。研究了多级复合材料蜂窝结构平压性能随结构等效密度变化的关系。并对多级复合材料蜂窝结构的三点弯曲性能进行了研究，主要包括理论预报和试验验证。通过理论研究对结构的失效模式进行了预报，绘制了失效模式机制图，并通过三点弯曲试验对理论预报结果进行了验证。 According to hierarchical structural design idea, a high-performance polymethylallyl imide (PMI) foam was added between the unidirectional carbon fiber reinforced resin composite to prepare hierarchical composite honeycomb structure. The out-of-plane compressive performance of hierarchical composite honeycomb structures were studied, including the theoretical prediction and experimental verification of the out-of-plane compressive performance of hierarchical composite honeycomb structures. The relationship between the out-of-plane compressive properties of hierarchical composite honeycomb structure and the structural equivalent density was studied. The three-point bending performance of hierarchical composite honeycomb structure was studied, including theoretical prediction and experimental verification. The failure mode of the structure was predicted by theoretical research, the failure mode mechanism diagram was drawn, and the theoretical prediction results were verified by three-point bending test. 国家重点基础研究发展规划（973项目）（2011CB610303
