Nov 01, 2020· 1. Introduction. Ultra-high-molecular-weight polyethylene (UHMWPE) materials, such as fibers, sheets, and thin films, have shown great potential to be used as body armor materials, because of their high strength, high toughness, and low density [1,2].For example, the theoretical ultimate tensile strength of UHMWPE in the molecular chain direction can be as high as 33–66 GPa [], which is ...
