摘要

摘要: 为了解决蜂窝夹层结构材料的开裂和分层问题，以玄武岩纤维长丝纱和碳纤维长丝纱为原料，在普通织机上，经合理设计，织造了顶层为透波层、中间层为吸波层和底面为反射层的蜂窝状三维整体机织结构型吸波织物；其次，以蜂窝状三维整体机织结构型吸波织物为增强体，双酚A型环氧树脂为基体，羰基铁粉(CIP)和炭黑(CB)为吸波剂，采用真空辅助树脂传递模塑(VARTM)成型工艺，制备了不同结构参数的蜂窝状三维整体机织结构型吸波复合材料；最后，采用矢量网络分析仪和万能试验机分别对蜂窝状三维整体机织结构型吸波复合材料的吸波性能和力学性能进行研究。研究表明，其有良好的整体性能，兼具吸波和承载能力。

Abstract: In order to solve the problems of cracking and delamination of honeycomb sandwich structure materials, basalt fiber filament yarn and carbon fiber filament yarn were used as raw materials, the honeycomb 3D integral woven structure microwave absorbing fabric was fabricated with the top layer as the wave transmitting layer, the middle layer as the wave absorbing layer and the bottom layer as the reflecting layer on the ordinary loom through reasonable design; Secondly, honeycomb 3D integral woven structure microwave absorbing composites with different structural parameters were prepared by vacuum assisted resin transfer molding (VARTM) process with honeycomb three-dimensional integral woven structure microwave absorbing fabric as reinforcement, bisphenol A epoxy resin as matrix, carbonyl iron powder (CIP) and carbon black (CB) as microwave absorbing agent; Finally, the microwave absorbing and mechanical properties of honeycomb 3D integral woven structure microwave absorbing composites were studied by vector network analyzer and universal testing machine. The research shows that it has good overall performance, both wave absorption and bearing integration.
