Abstract

This study aims to identify the influence of resin permeation on ballistic responses of fabric laminates. According to experimental results, when the resin permeation degree was improved, the yarn mobility was greatly constrained due to increasing of the bonding force, and the specific energy absorption of laminates under ballistic impact was degraded in comparison with that of the neat fabric. Different resin permeation states in a single yarn and fabric were simulated through Finite Element (FE) modeling at a fiber-bundle level. For a given resin ratio of 15%, semi-permeation of resin in a single yarn was benefit for energy absorption due to even distribution of impact load at the early impact, but full-permeation of resin resulted in energy absorption degradation due to high stress concentration and premature failure. For laminate models, the yarn mobility was severely constrained not only by resin bonding but also by yarns interlacement. In comparison with the neat fabric, stress distribution area on laminates was decreased 30–70%. Yarns contribution to energy absorption was significantly reduced in particular for principal yarns. Such results indicated that perfect resin permeation in armor-grade composite played a negative effect on ballistic energy dissipation due to low material utilization efficiency.

树脂渗透对织物层压板弹道行为影响的实验和数值研究

本研究旨在确定树脂渗透对织物层压板弹道响应的影响。实验结果表明，当树脂渗透度提高时，由于粘合力的增加，纱线的流动性受到很大限制，层压织物在弹道冲击下的比能量吸收与纯织物相比有所下降。通过有限元（FE）建模，在纤维束水平上模拟了单根纱线和织物中不同的树脂渗透状态。在给定的 15% 树脂比率下，单根纱线中的半渗透树脂有利于吸收能量，因为在早期冲击时冲击载荷分布均匀，但全渗透树脂则会导致能量吸收能力下降，因为应力集中和过早失效。对于层压模型，纱线的流动性不仅受到树脂粘合的严重限制，还受到纱线交错的限制。与纯织物相比，层压板上的应力分布面积减少了 30-70%。纱线对能量吸收的贡献明显降低，尤其是主纱。这些结果表明，由于材料利用效率低，装甲级复合材料中的完美树脂渗透对弹道能量耗散产生了负面影响。

期刊介绍： The past few decades have seen outstanding advances in the use of composite materials in structural applications. There can be little doubt that, within engineering circles, composites have revolutionised traditional design concepts and made possible an unparalleled range of new and exciting possibilities as viable materials for construction. Composite Structures, an International Journal, disseminates knowledge between users, manufacturers, designers and researchers involved in structures or structural components manufactured using composite materials. The journal publishes papers which contribute to knowledge in the use of composite materials in engineering structures. Papers deal with design, research and development studies, experimental investigations, theoretical analysis and fabrication techniques relevant to the application of composites in load-bearing components for assemblies, ranging from individual components such as plates and shells to complete composite structures.
