蜂窝状三维机织复合材料的制备及压缩失效行为研究
Study on preparation and compression failure behavior of 3D woven honeycomb composite materials
摘要
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 estab-lished 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 compres-sive performance of the honeycomb.关键词
