2022-10-27
High-performance fiber has special properties not found in ordinary fibers and is a high-quality engineering material with the following characteristics. High performance fibers have high temperature resistance, have high temperature dimensional stability and low thermal shrinkage, so they have special use in heat resistant protective materials.
High-performance fiber has special properties not found in ordinary fibers and is a high-quality engineering material with the following characteristics.
(1) Very high mechanical properties. High strength and high modulus of elasticity. Advances in fiber materials have made it possible to manufacture advanced composite materials. The modulus of elasticity is an important indicator of the material, such as steel fibers commonly used in engineering is 200 GPa, titanium alloy for manufacturing aircraft is 106 GPa, aluminum alloy is 71 GPa, while the modulus of PPTA fiber is 132 GPa, and PBO fiber is even higher than 280 GPa.
(2) High performance fibers have high temperature resistance, have high temperature dimensional stability and low thermal shrinkage, so they have special use in heat resistant protective materials.
(3) Another advantage of high-performance fibers is the low density, which is conducive to the light weight of products.
(4) Organic high-performance fibers are easy to process and easy to mold.
(5) Organic and inorganic high performance fibers are corrosion resistant.
