What are the main characteristics of high performance fiber compared with conventional chemical fiber?

(1) extremely high mechanical properties. High strength and high elastic modulus. The progress of fiber materials makes it possible to manufacture advanced composite materials. Elastic modulus is an important index to measure materials, such as 200GPa for steel fiber, 106GPa for titanium alloy, 7 1 GPa for aluminum alloy, 132GPa for PPTA fiber and 280GPa for PBO fiber.

(2) High-performance fiber has high temperature resistance, stable size at high temperature and low thermal shrinkage, so it has special use in heat-resistant protective materials.

(3) Another advantage of high-performance fiber is its low density, which is beneficial to the lightweight of products.

(4) Organic high-performance fibers are easy to process and shape.

(5) Organic and inorganic high-performance fibers are corrosion resistant.
