What are the performance characteristics of carbon fiber?
1 Answers
Carbon fiber has the following characteristics: 1. High-temperature resistance: Carbon fiber is a high-strength, high-modulus fiber with a carbon content of over 90%. It has the highest temperature resistance among all chemical fibers. It is made from acrylic and viscose fibers through high-temperature oxidation and carbonization, making it an excellent material for manufacturing high-tech equipment such as aerospace components. 2. Friction resistance: It features electrical conductivity, thermal conductivity, and corrosion resistance. Its fibrous and soft form allows it to be processed into various fabrics. Due to the preferred orientation of graphite microcrystals along the fiber axis, it exhibits high strength and modulus in the fiber direction. 3. Low density: This results in high specific strength and specific modulus. The primary use of carbon fiber is as a reinforcing material combined with resins, metals, ceramics, and carbon to create advanced composite materials. Carbon fiber-reinforced epoxy resin composites have the highest strength and specific modulus among existing engineering materials.
