Business opportunities in the international market contains fiber varieties – Pr
According to the information on the current international market opportunities for fiber contains many varieties, generally can be divided into three categories: high-performance fiber, green fiber, polyester fiber.
1, high-performance fiber
High-performance fiber in organic and inorganic fibers. High-performance fiber used for both aerospace, aviation and military art in the field, but also for sports, health, automotive, construction, agriculture, marine development, energy, environmental protection and other industries. As enhanced by the high-performance fiber composite material consisting of cutting-edge future there will be hot in the international market situation.
High-strength polyethylene fiber
The proportion of high-strength polyethylene fiber is the smallest of all the high-performance fibers, it has the highest ratio of strength; its specific modulus and impact resistance, even better than Kevlar; It also has a low temperature, fatigue resistance, wear , UV and electrical insulation and other excellent performance. These excellent properties make it with carbon fiber, Kevlar listed as the world's three major high-performance fibers.
Widely used in high-strength polyethylene fiber for defense, aerospace, security, marine engineering, sports equipment, electrical communications, medical materials and other fields, such as composite materials, reinforcing fibers, used in bullet-proof vests, ballistic helmets; or with aromatic Lun with production of high strength, wear and fatigue resistance of the rope, fishing line, nets, protective nets. As the high-strength polyethylene, light weight, resistance to fatigue, it is used extensively for various vibration plate; other aircraft in the radar composite, geotechnical construction also use it as reinforcement material.
Carbon Fiber
On the physical properties of carbon fiber has a strength, modulus is high. Because carbon fiber is solely composed of carbon, so it does not burn, chemically stable, free from acids, solvents and salt corrosion. Carbon fiber thermal expansion coefficient is small, the small changes in mechanical properties at high temperatures. Carbon fiber with good conductivity, can reflect electromagnetic waves, electromagnetic sealing performance, X-ray through good performance.
Because carbon fiber has such excellent performance, its extremely broad range of applications. Made of carbon fiber composite material that can be used for aerospace, aviation, automotive industries, this composite material, high strength, impact resistance, light weight, can significantly reduce the spacecraft, airplanes, cars, etc. to run the energy consumption, reducing operating costs . Also in the wings of wind engines, marine oil stent platform, lifting frame, and control structure, oil production equipment, soft coil, rapier, rapier, rapier head, fishing rod, golf clubs, tennis racket frame, ski, car frame, rowing, in the construction industry such as alternative steel, carbon fiber has a wide range of applications.
PBO fiber
PBO fiber has high strength, high modulus, heat resistance, flame retardant and other features, its strength, modulus of Kevlar fiber twice, and between the aramid and heat with fire resistant. PBO fiber limiting oxygen index of 68, organic fiber, flame retardant in the highest. PBO fiber flexibility good, woven polyester fabric similar to fabric softness, very favorable for the textile weaving process. PBO fiber chemical resistance, cutting resistance is better, as a protective material has a good effect. PBO drawback is poor lightfastness, UV affected by the strength of fibers, so use should be protected from light.
The use of PBO fiber can be divided into two categories, namely the application of heat resistance and mechanical properties of reinforced materials in the application. Application of heat-resistant materials, the most suitable for the aluminum industry and the glass industry during the manufacturing process out of the buffer packing material can also be used for fire service, blast furnace work clothes, welding clothes and other heat-resistant clothing, high temperature resistant filter material filtration. The enhanced mechanical properties of the application of a wide range of materials can be used for tires, conveyor belts, hose and other rubber reinforcement material, concrete reinforcement material, anti-cuts protective clothing, safety gloves, safety bar, car service, pilot service and other active sportswear and sports equipment, make use of PBO fiber composite material can be used in missiles, spacecraft, aircraft, boats, vibration board.
Aramid
In addition to the physical properties of Kevlar that has the characteristics of high strength and high modulus, but also has a high temperature, impact resistance, low weight, good performance and processing advantages. Aramid advantage of its resistance to impact and tensile strength of carbon fiber for high-performance combination of sophisticated composite materials for aerospace, aviation industry, a large number for the bullet-proof vest, bulletproof helmet and other protective items; addition, it also is widely used making ropes, nets, tire cord, conveyor and other industrial products.
Polyimide fibers
Polyimide fibers have good mechanical properties, high strength. It is highly resistant to high radiation, high energy -ray irradiation with 8000, the fiber strength and electrical properties remain basically unchanged; addition to its highly heat-resistant, not only temperature, but low temperature. Polyimide fibers is extremely good electrical insulation, non-toxic, flame retardant.
Polyimide fibers can be used in aerospace, nuclear power stations, fuel gas filters, high heat insulation screen carpet radiant heat, high temperature fire protective clothing, flame retardant racing suits, armored units and the flight suit and other protective clothing. Polyimide fiber composites can be widely used in high-tech industries such as aviation cable, high temperature electrical insulation, air rocket motor nozzle structural materials in nuclear facilities, aircraft engine structural materials.
