Abstract

The study reveals the combination of shear thickening gel (STG) with angle interlocking fabrics with different thickness direction binding modes to prepare flexible composites. The effect of thickness direction binding modes on flexible composites' ballistic performance and failure mechanisms are systematically investigated. The results reveal that the bullet penetrates STG and yarn simultaneously during the impact phase, causing STG to produce the shear thickening effect. Flexible composites produce synergistic energy absorption. The layer-to-layer structure has a 4.49 % higher ballistic limit than the through-thickness structure, proving superior impact resistance. This investigation aims to enhance the design of lightweight ballistic composites by examining the failure mechanisms of flexible composites in response to ballistic impacts.

期刊介绍： Composites Communications (Compos. Commun.) is a peer-reviewed journal publishing short communications and letters on the latest advances in composites science and technology. With a rapid review and publication process, its goal is to disseminate new knowledge promptly within the composites community. The journal welcomes manuscripts presenting creative concepts and new findings in design, state-of-the-art approaches in processing, synthesis, characterization, and mechanics modeling. In addition to traditional fiber-/particulate-reinforced engineering composites, it encourages submissions on composites with exceptional physical, mechanical, and fracture properties, as well as those with unique functions and significant application potential. This includes biomimetic and bio-inspired composites for biomedical applications, functional nano-composites for thermal management and energy applications, and composites designed for extreme service environments.
