Para Aramid Fibers Use For Bulletproof Vest Aramid Fiber Reinforced Plastic

para aramid fiber:
The mechanical properties of high strength and high modulus : a strong hydrogen bond strength , strength of up to 28 g / D more, than the strength of steel wire 5 to 6 times higher than the modulus of steel wire or glass fiber 2 to 3 times, toughness steel wire are two -fold , and weighs only wire about 1/5 .
Temperature resistance : Continuous use temperature range is extremely wide, -196 °C to 204 °C in the range of long-term operation . At 500 °C high temperature does not decompose , does not melt , at 200 °C undergo 100 hours , still maintain the original strength of 75%.
Good chemical solvent properties : acid, anti-aging, have a good adhesion to rubber .
Reinforcements
Long Kevlar fiber has a high tensile strength, low elongation , high elastic modulus , non-conductive , corrosion resistance, low thermal high toughness, high shear strength , fire resistance and other outstanding features , widely used in engineering and construction , rubber , cable reinforcement, high strength rope and other fields.
Protective materials
Kevlar has high strength and high modulus , high temperature resistance , corrosion resistance, flexibility and low shrinkage properties, can be made of high-temperature protective clothing , cut-resistant gloves body armor, ballistic helmets , etc., is an ideal material for the field of personal protection .
Composites
Kevlar has a high tensile strength, low density, small elongation , flexural strength characteristics with resin , rubber and other composite materials , can significantly reduce component weight , increased payload , for the production of aerospace equipment, high-speed trains and yacht housing and so on.
Friction and sealing materials
Kevlar has high strength and high modulus , high temperature resistance, good toughness, fatigue and other outstanding features , can be used as friction material reinforced fiber ( asbestos substitutes ) , significantly improve wear resistance, suitable for high temperature conditions.
Sports Equipment
Kevlar also be processed into insulating circuit boards, high-strength webbing , pipelines , specialty paper and golf clubs, tennis rackets , skis and other sports equipment , production in people , many areas of life play an increasingly important role.
