Aviation sector

Aramid/polyethylene fiber has low density, high strength and good corrosion resistance. It can be used to manufacture rocket engine shells of missiles, as well as wide-frequency wave-transmitting materials for aircraft and spacecraft fuselages, main wings, and tail wings, and can withstand impact forces. Structural components. The multi-layer honeycomb structure plate prepared by impregnating aramid cloth with epoxy resin to form aramid prepreg and directly bonding with honeycomb or foam structure has outstanding impact resistance and electromagnetic wave permeability. The super-hybrid composite laminate formed by overlapping and hot pressing of aramid, thin aluminum plate and epoxy non-weft cloth has extremely high specific modulus and specific strength, and its fatigue life is 100 times to 1000 times that of aluminum alloy plates. It can be used on the fuselage of aircraft and other parts. The resin-based reinforced composite material made of aramid fiber is applied to the aircraft passenger body, which can greatly reduce the total weight of the aircraft.

Military field

With the development of new military weapons such as chemical and nuclear weapons, there are more new requirements for the performance of military protective clothing: durability, lightness, bulletproof, flame retardant, and good environmental adaptability and camouflage. Bulletproof vests and bulletproof helmets made of aramid fibers can replace old-fashioned nylon vests and tank helmets. Adding a proper amount of aramid to bulletproof vests and helmets can not only make them small and light, but also increase their bulletproof performance by 40%. . The soft bulletproof vest made of high-grade bulletproof aramid non-weft fabric and high-performance polyethylene film has better bulletproof performance and heat resistance than ultra-high molecular weight polyethylene fiber. Aramid fiber can also be compounded with other materials (such as metals, ceramics, etc.) to make various high-strength, impact-resistant explosion-proof tanks, bulletproof shields, and bulletproof armor plates. In addition, bonding the aramid fiber fabric to the inner wall of the structure can effectively absorb the explosion wave and prevent the shrapnel from harming the human body.

Construction sector

The ductility of aramid fiber fabric is better than that of carbon fiber. The material itself is light in weight and flexible in degree of freedom. It is an ideal reinforcement material for construction engineering, especially when strengthening irregularly shaped components. There is no need to chamfer. Kevlar is woven into a steel bar, which can be used as a cement-reinforced skeleton for large buildings. In addition to the advantages of high strength and light weight, it is also corrosion-resistant and can at the same time play a better anti-shearing effect.

Traffic field

Because of the low density of aramid fiber, it can withstand high and low temperatures, and has good adhesion to rubber. It can be used as tire cord for automobiles or airplanes. The tire made of aramid fiber has light weight, thin tire, low rolling resistance, high tire bearing capacity, good wear resistance, cut resistance and puncture resistance, and the ground pressure center of gravity during the use of the tire The movement is small, the steering performance is good, the heat is easy to radiate, and it is not easy to deform, which improves the car’s ride comfort, prolongs the service life of the tires, and can meet the requirements of modern supersonic aircraft for the use of tires.

Electronic and electrical field

Aramid fiber has higher strength and modulus and lower dielectric coefficient, and good electromagnetic wave transmittance. Under the same rigidity condition, the thickness of the radar antenna shield made of aramid composite material can be reduced by 30 than that of glass fiber composite material. %, the electromagnetic wave transmittance is increased by 10%; The linear expansion coefficient matching degree of the laminated substrate made of aramid and epoxy, phenolic, polyimide and other resins and ceramics is relatively high. It can cause cracking and can be used to make special printed circuit boards in surface mounting technology, which is conducive to the miniaturization and lightness of electronic equipment. Utilizing the characteristics of high strength and high temperature resistance of aramid fiber, it is used as the "tension member" in the optical fiber, which can protect the small and fragile optical fiber from being stretched and deformed when subjected to tension, and will not affect the transmission of light. The composite product of aramid fiber and carbon fiber has good processability and semiconductor properties, and can withstand high temperatures. It is mostly used to make materials for reducing electric field in high-voltage devices. Aramid paper has good insulation properties after being impregnated with insulating varnish, and is used as an insulating material for heat-resistant motors in combination with natural mica sheets.

Other areas

Aramid fiber molecules contain a large number of benzene rings, have good chemical stability, corrosion resistance, high specific strength, lightness and firmness, and can be used to make cables for marine vessels and deep wells. Utilizing the characteristics of high temperature resistance and fatigue resistance of aramid fiber to produce high-grade rackets, fishing rods, sleds, snowboards, ski poles, bows and arrows, rowing boats, golf clubs, etc., it can also be used to make hiking shoes with harsh sports conditions Boots, boxing gloves, racing helmets, racing car bodies, etc. As asbestos is a serious hazard to the human respiratory tract, aramid can be substituted for asbestos to make reinforced rubber seals and other seals, which are used for automobile brake pads and linings.
