为了研究碳纤维蜂窝复合材料的成型结构对其压缩性能的影响，制备了具有相同几何尺寸的一维单向铺层、二维织物铺层以及三维机织一体成型结构的碳纤维蜂窝复合材料，对其压缩性能进行了测试，并对比分析了三种结构碳纤维蜂窝复合材料的抗压缩性能。结果表明：三种碳纤维蜂窝复合材料的面外压缩强度差别不大，均远高于面内压缩强度（约10倍以上）；三种碳纤维蜂窝复合材料的面内压缩强度差异较大，一维单向铺层蜂窝复合材料的面内X方向压缩强度明显高于二维织物铺层和三维机织一体成型结构的蜂窝复合材料，分别高出40%和36%，而在面内Y方向，三维机织一体成型结构蜂窝复合材料的压缩强度比一维单向铺层和二维织物铺层的蜂窝复合材料分别提高了20%和39%，且由于层间接结纱的作用，三维机织一体成型结构能够有效抑制层间开裂损伤。研究表明，三维机织一体成型结构对提升蜂窝复合材料的抗压缩性能有积极作用。
Abstract：To investigate the effect of the forming structure of carbon honeycomb composites on their compression performance,carbon honeycomb composites with the same geometric dimensions and three different forming structures(1D unidirectional layering, 2D fabric layering, and 3D woven integrated forming structure) were prepared. Compression performance tests were conducted to compare and analyze the compression resistance of the three types of composites. The results reveal that the out-of-plane compression strengths of all three composites have little difference and all are much higher than the in-plane compression strengths(approximately 10 times or more). However,significant variations are observed in their in-plane compression performance.The unidirectional one-dimensional honeycomb composite exhibited 40% and 36% respectively higher compression strength in the in-plane X-direction compared to that of the two-dimensional and three dimensional composites. In the in-plane Y-direction,the three-dimensional woven composite demonstrates superior performance, with compression strength 20% and 39% respectively greater than that of the unidirectional and two-dimensional composites. Moreover, due to the effect of the interlayer binding yarns, interlayer cracking damage can be effectively inhibited. The study indicates that the 3D woven integrated forming structure plays a positive role in improving the compression resistance of honeycomb composites.
