摘要: 为解决蜂窝结构在使用过程中蜂窝壁黏结处易开裂的结构失效性问题,本文以1 000 D芳纶长丝为增强体,环氧树脂为基体,使用2.5D织机和真空辅助树脂传递模塑(VARTM)工艺制备了一体化纤维增强结构的蜂窝状三维机织复合材料,并分析得出在受到面外载荷的情况下,蜂窝状三维机织复合材料的破坏模式为纤维断裂和基体破坏及蜂窝整体的压溃和屈曲折叠破坏。为了更加准确地探究蜂窝状三维机织复合材料在受到面外压缩载荷时的力学响应和损伤演化,通过数值仿真的方法,建立了蜂窝状三维机织复合材料多尺度损伤模型,通过和试验结果进行对比,发现两者具有良好的吻合性,最后对蜂窝状三维机织复合材料进行了结构参数化的讨论,探究了蜂窝边长、壁厚对蜂窝面外压缩性能的影响。

Abstract: To address the issue of structural failure due to cracking at the adhesive joints of honeycomb walls during use, this paper utilizes 1 000 D aramid fibers as reinforcement and epoxy resin as the matrix. A 2.5D loom and vacuum assisted resin transfer molding (VARTM) process were used to prepare an integrated fiber-reinforced honeycomb three-dimensional woven composite material. The failure modes of the honeycomb three-dimensional woven composite material under out-of-plane loads were analyzed, revealing that the failure modes include fiber breakage, matrix failure, and overall crushing and buckling collapse of the honeycomb structure. To more accurately investigate the mechanical response and damage evolution of the 3D woven honeycomb composite material under out-of-plane compressive loads, a multi-scale damage model of the 3D woven honeycomb composite material was established using numerical simulation. By comparing the model with experimental results, it was found that the two show good agreement. Finally, a structural parameterization discussion of the 3D woven honeycomb composite material was conducted, exploring the influence of honeycomb side length and wall thickness on the out-of-plane compressive performance of the honeycomb.

Key words: honeycomb structure, 3D woven composite material, out of plane compressive behavior, multi-scale simulation
