It is precisely because of the microstructure of UHMWPE with high orientation and crystallinity that determines the structural properties that the fiber has excellent material properties. These properties also determine its application direction.
1. Aerospace field
Ultra-high molecular weight polyethylene fiber composites are often used in wing tips and spacecraft structures of various aircraft. In addition, the shell materials of armed helicopters and fighter planes also use this composite material. Cables and parachutes on airplanes are made of this fiber.
2. National defense and military affairs
Ultra-high molecular weight polyethylene fiber is often used to prepare bulletproof materials such as bulletproof vests, combat helmets, protective decks of ships and armored vehicles, missile and radar shields, etc. At present, abroad and abroad, ultra-high molecular weight polyethylene fiber reinforced resin composites are used to replace aramid fiber reinforced resin composites to prepare bulletproof and explosion-proof helmets.
3. Civil field
Rope, cable, fishing gear and sail can be made of UHMWPE fiber. In sports equipment, snowboards, surfboards, bicycle frames and helmets can all use ultra-high molecular weight polyethylene fiber reinforced composites. Because of its good biocompatibility, some biomedical materials, such as medical sutures, artificial limbs, artificial joints and artificial ligaments, can be made of ultra-high molecular weight polyethylene fibers. In industry, ultra-high molecular weight polyethylene fiber is widely used, such as automobile buffer plate, filter material, conveyor belt, etc. Walls, partitions and other structures in the field of architecture can also be used to improve the toughness of cement and prepare fiber reinforced cement-based composites.
