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. |
