摘要: 本文设计开发了两种不同织物结构增强的复合材料。基于这种新型多层多向角联机织结构,通过多轴向力学测试(拉伸、压缩及面内剪切),结合数字图像相关(Digital Image Correlation,DIC)技术和失效界面微观形貌分析,系统表征了经、纬向加载试样的损伤演化机制及其与织物结构的关联。试验数据表明,不同织物结构制成的三维多向机织复合材料,其内部承载纤维体积含量和聚集状态不同,对其力学性能产生不同影响。承载纤维体积含量较高且呈集中分布结构的复合材料,其性能提升显著。

Abstract: In this paper, two kinds of composite materials reinforced with different fabric structures were designed and developed. Based on this new multi-layered multi-directional angle-knitted structure, the damage evolution mechanism of the warp and weft loaded specimens and its correlation with the fabric structure were systematically characterized through multiaxial mechanical testing (tension, compression and in-plane shear), combined with digital image correlation (DIC) technology and failure interface micro-topography analysis. Experimental data show that three-dimensional multi-directional woven composites made from different fabric structures have different effects on their mechanical properties due to different volume content and aggregation state of internal load-bearing fibers. Composites with a higher volume content of load-bearing fibers and a concentrated distribution structure exhibited significantly improved mechanical performance.

Key words: Multilayer-multidirectional, fabric structure, tension, compression, in-plane shear, failure mechanism
