1. Introduction Click to copy section linkSection link copied! Ultrahigh molecular weight polyethylene (UHMWPE) fibers have been widely adopted for applications such as ballistic armor protection, (1) due to their high strength and energy-absorption capability while being lightweight. (2−4) The fibers are either solution-grown or gel-spun (5,6) and drawn, resulting in 95% molecular orientation in the drawing direction with a degree of crystallinity of 97.5%.
