National Defense
Due to its good impact resistance and high specific energy absorption, the fiber can be made into protective clothing, helmets, and bulletproof materials in the military, such as armor plates for helicopters, tanks and ships, radar shields, and missile shields. , bulletproof vests, stab-proof vests, shields, etc., among which the application of bulletproof vests is eye-catching. It has the advantage of being soft and bulletproof better than aramid, and it has become the main fiber occupying the US bulletproof vest market. In addition, the specific impact load value U/p of the ultra-high molecular weight polyethylene fiber composite material is 10 times that of steel, and more than 2 times that of glass fiber and aramid fiber. Bulletproof and anti-riot helmets made of the fiber-reinforced resin composite material abroad have become substitutes for steel helmets and aramid reinforced composite helmets.
Aviation
In aerospace engineering, due to its light weight, high strength and good impact resistance, the fiber composite material is suitable for wingtip structures of various aircraft, spacecraft structures and buoy aircraft. The fiber can also be used as a deceleration parachute for space shuttle landings and ropes for suspending heavy objects on aircraft, replacing traditional steel cables and synthetic fiber ropes, and its development is extremely rapid.
Civil aspects
(1) Application of ropes and cables: ropes, cables, sails and fishing gear made of this fiber are suitable for marine engineering and are the original use of this fiber. Commonly used in negative force ropes, heavy duty ropes, salvage lines, drag lines, sailing lines and fishing lines. The breaking length of the rope made of this fiber under its own weight is 8 times that of the steel rope and 2 times that of the aramid fiber. The rope is used for the fixed anchor ropes of super tankers, marine operating platforms, lighthouses, etc., which solves the reduction of cable strength and fracture caused by corrosion, hydrolysis, and ultraviolet degradation of nylon and polyester cables that were encountered in the past using steel cables. , need to be replaced frequently.
(2) Sports equipment supplies: Safety helmets, snowboards, sailboards, fishing rods, rackets, bicycles, gliders, ultra-lightweight aircraft parts, etc. have been made into sporting goods, and their performance is better than traditional materials.
(3) Used as a biological material: The fiber-reinforced composite material is used in dental tray materials, medical implants and plastic sutures, etc. It has good biocompatibility and durability, and has high stability. Cause allergy, has been used for clinical application. It is also used in medical gloves and other medical measures.
(4) Industrially, the fiber and its composite materials can be used as pressure-resistant containers, conveyor belts, filter materials, automobile buffer boards, etc.; in construction, it can be used as walls, partition structures, etc. Improve the toughness of cement and improve its impact resistance.
Uses: bulletproof vests and helmets, lightweight armor, sails, cables, fiber optic cable reinforcements, parachutes and filter media, etc.
