Numerical simulation of the protective properties of ceramic/fiber composite ballistic materials

Abstract With the development of technology, bulletproof vests need to have better impact resistance, but the experiment is difficult, costly, and dangerous. Using ANSYS finite element software is an effective alternative. This paper focuses on the impact resistance of composite materials composed of boron carbide ceramics and UHMWPE ultra-high molecular weight polyethylene fibers, respectively, to change the thickness of the two materials to get the effect of the target plate thickness on the performance of the material target plate. Finally, the obtained boron carbide ceramic thickness of 14mm and fiber thickness of 12mm, that is, 24 layers, allowed the material target plate to effectively intercept the bullet, which is in line with expectations.
