High Performance Bulletproof Material: UHMWPE Fiber

    With the rapid development of science and technology, the destructive power of various weapons is becoming stronger, and police officers and the military have higher requirements for protective equipment. How to improve the protective performance of products is a technical test. Therefore, countries around the world are constantly developing various high-quality bulletproof materials, among which polyethylene fiber, aramid, graphene, and liquid bulletproof materials are currently known as the mainstream bulletproof materials.

    UHMWPE fiber is one of the three high-tech fibers in the world today (carbon fiber, aramid fiber, and UHMWPE fiber), and it is also the toughest fiber in the world, also known as high-strength and high-modulus polyethylene fiber.

    UHMWPE is odorless tasteless and nontoxic. It is highly resistant to corrosive chemicals. It is highly resistant to abrasion and can reach 15 times more resistant to abrasion than carbon steel under certain conditions. Its coefficient 0 friction is significantly lower than that of nylon and acetal, and is comparable to that of polytetrafluoroethylene (PETE, Teflon), but UHMWPE has better abrasion resistance than PTEE.

    The continuous weft free fabric made of UHMWPE fiber is the best soft material for blocking bullets. It has a single oriented multi-layer structure, in which fibers are not interwoven but arranged parallel to each other. For different bulletproof requirements, a soft long chain structure in high-strength and high modulus polyethylene fibers of different specifications is used to quickly disperse the impact energy of the bullet over a larger area, thereby reducing the depth of the vest's indentation and reducing non penetrating injuries.

    Its strength is 15 times that of steel and 2 times higher than carbon fiber and Kevlar fiber. It is the fiber with the highest strength and specific modulus, and is currently the main material for manufacturing bulletproof vests.
