防弹混杂复合材料设计及其抗冲击性能研究

Study on Design,Preparation and Impact Resistance of Bulletproof Hybrid Composites

层间混杂复合材料在抗冲击能力上具有得天独厚的优势,是制备轻武器防护甲板的最佳候选者。本文通过对比多种材料属性,综合考虑材料性能、制造成本、工艺性等因素,选择氧化铝为陶瓷面板,凯芙拉纤维为主要增强材料,高强玻纤为次要增强材料制备了混杂复合材料板,并对其抗冲击性能进行了有限元模拟。在经过结构优化后,复合材料防护板可以经受平均速度为400m/s的手枪平头子弹射击。

Interlaminar hybrid composites have unique advantages in impact resistance and are the best candidates for preparing protective decks for small arms.In this paper,by comparing the properties of a variety of materials and considering material properties,manufacturing cost,technology and other factors,alumina was selected as the ceramic panel,Kevlar fiber as the main reinforcement material,and high-strength glass fiber as the secondary reinforcement material to pre-pare the hybrid composite plate,and its impact resistance was simulated by finite element method.After structural optimization,the composite shield can withstand a pistol flat bullet with an average speed of 400m/s.
