Numerical analysis of ballistic impact performance of two ceramic-based armor structures

Composites Part C: Open Access, 2020
This paper investigates ballistic performance of two different ceramic-based armor designs using finite element analysis. The first design is a bi-layer armor consists of a ceramic front layer and a Kevlar-29 composite backing layer.

Research on ballistic performance of green shear thickening functionalized fabric based on solid waste modification

Materials & Design
Based on the solid waste-based modification, green shear-thickening functionalized ballistic composites were prepared. Silica aerosols were obtained from solid waste diatomaceous earth through sol–gel preparation, gel aging, and supercritical drying. The

Experimental and numerical study on CuO/ZnO-modified aramid fabric for ballistic and UV radiation protection

Polymer Testing
Aramid fabrics are widely used in bulletproof armor because of their excellent mechanical properties. Previous studies have shown that ultraviolet radiation has a negative effect on the mechanical properties of aramid yarn, so improving the mechanical ...
