What is the high temperature resistance of carbon fiber?
1 Answers
Carbon fiber composites with ceramic as the matrix can withstand temperatures above 2,000 degrees Celsius in aerospace applications, although the high technology and cost make it difficult to achieve industrial-scale use. Here are specific details about carbon fiber: 1. Definition: A high-strength, high-modulus fiber with a carbon content exceeding 90%. It has the highest temperature resistance among all chemical fibers. Produced using polyacrylonitrile and viscose fiber as raw materials through high-temperature oxidation and carbonization, it is an excellent material for manufacturing high-tech equipment such as aerospace components. 2. Main Applications: 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 exhibit the highest specific strength and specific modulus among existing engineering materials. 3. Characteristics: A special fiber composed of carbon elements. It features high-temperature resistance, friction resistance, electrical conductivity, thermal conductivity, and corrosion resistance. With a fibrous, soft appearance, it can be processed into various fabrics. Due to the preferred orientation of its graphite microcrystalline structure along the fiber axis, it demonstrates exceptional strength and modulus in the fiber direction. Carbon fiber's low density results in high specific strength and specific modulus.
