摘要: 由陶瓷和纤维制成的复合插板具有优异的抗冲击性能,被广泛应用于防弹衣插板。本文通过实弹靶试研究了碳化硼(B4C)陶瓷和芳纶预浸料复合过程中成型压力对插板防弹性能的影响。实验发现B4C陶瓷/芳纶复合插板通常可以经受一至两发子弹的冲击,体现出较强的防弹能力。同时高压复合插板具有较高刚度,可以降低中弹后弹痕的深度;而低压复合插板具有较高的韧度和拉伸变形能力,可以降低背板被击穿的概率。本研究对制作高性能陶瓷-纤维复合防弹衣插板具有重要指导意义。

Abstract: Composite inserts made of ceramics and fibers are widely used for body armors due to their high impact-resistance. In this paper, the influence of forming pressure on the efficacy of B4C ceramic-aramid prepreg bulletproof was studied by bullet target test. It is found that the B4C ceramic-aramid composite insert can usually withstand the impact of one or two bullets, showing pretty good ability of bulletproofing. Our experiment also reveals that high-pressure leads to a harder plate, which reduces the depth of the depression by the bullet. Whereas, low-pressure leads to higher tensile strength and stretch ability of the plate, which reduces the probability of penetrating. Our work has applicative significance in the fabrication of high-performance ceramic-fiber composite body armor inserts.
