Material: carbon fiber Material: 304 Stainless Steel Length: 9.3 Width 5.8 Thickness: 1 Origin: Made in Taiwan The characteristics of carbon fiber, such as high hardness, high strength, light weight, high chemical resistance, high temperature resistance and low thermal expansion, make it very popular in aerospace engineering, civil engineering, military, racing and other competitive sports products. However, compared to similar fibers such as glass or plastic fibers, carbon fiber is quite expensive. Carbon fiber is often combined with other materials to form composite materials. Carbon fiber-reinforced polymer (also commonly known as carbon fiber) that has a very high strength-to-weight ratio when mixed with plastic resins and wound or molded. However, carbon fiber is also compounded with other materials such as graphite to form high-temperature-resistant carbon-carbon composites.
