Developing auxetic composite system for protective engineering applications

本项目旨在探索将拉胀技术的最新发展扩展到工程结构保护设计的可能性。当拉伸时，弹性材料在垂直于所施加的力的方向上变厚。具体而言，该项目计划开发一种新型拉胀复合材料系统，重点是保护民用和国防基础设施免受极端负荷的影响。预计该系统的上级能量耗散能力将使其应用范围扩大到民用基础设施之外，如装甲车辆、防护运动装备和防弹衣。该项目还计划开发一个多尺度数值建模和拓扑优化框架，以加速采用这种先进的复合系统。

This project intends to explore the possibilities of extending the latest developments in auxetic technologies to the protective design of engineering structures. Auxetic materials become thicker perpendicular to the applied force when stretched. Specifically, the project plans to develop a novel auxetic composite system with a focus on protecting civil and defence infrastructure from extreme loads. It is expected that the system’s superior energy dissipating capability will broaden its application beyond civil infrastructure, such as armoured vehicles, protective sports gear and body armour. The project also plans to develop a multiscale numerical modelling and topological optimisation framework to accelerate the adoption of this advanced composite system.
