The core advantage of this prepreg lies in its excellent ballistic protection and cut resistance performance. The Kevlar® 129 fiber has higher modulus than ordinary aramid fibers, ensuring better dimensional stability after molding. The polyamide resin system has good toughness, which can buffer external impact force and avoid secondary damage caused by fragment splashing. Compared with traditional steel protective materials, the components made of this prepreg can reduce the weight by more than 60%, greatly improving the mobility of protective equipment. The stable storage period of 9 months under conventional temperature conditions facilitates large-scale production and inventory management.
