Characteristics of carbon fiber
Characteristics of carbon fiber:
Carbon fiber is a high-strength, high-modulus fiber with a carbon content of 90% or more. High temperature resistance ranks first among all chemical fibers. It uses acrylic fiber and viscose fiber as raw materials and is carbonized by high temperature oxidation. It is an excellent material for manufacturing high-tech equipment such as aerospace.
It has the characteristics of high temperature resistance, friction resistance, electrical conductivity, thermal conductivity, and corrosion resistance. The appearance is fibrous, soft, and can be processed into various fabrics. Because its graphite microcrystalline structure is preferentially oriented along the fiber axis, it has a high Strength and modulus.
The density of carbon fibers is small, so the specific strength and specific modulus are high. The main use of carbon fiber is as a reinforcing material and resin, metal, ceramics and charcoal composite, manufacturing advanced composite materials. Carbon fiber reinforced epoxy resin composite materials have the highest specific strength and specific modulus among existing engineering materials.
Carbon fiber use:
The main use of carbon fiber is to composite with resin, metal, ceramic and other substrates to make structural materials. Carbon fiber-reinforced epoxy resin composite materials have the highest specific strength and specific modulus among the existing structural materials. In areas with strict requirements such as density, stiffness, weight, and fatigue characteristics, where high temperature and high chemical stability are required, carbon fiber composite materials are quite advantageous.
Carbon fiber was produced in the early 1950s in response to the needs of cutting-edge science and technology such as rockets, aerospace and aviation, and is now widely used in sports equipment, textiles, chemical machinery and medical fields.
With the increasingly stringent requirements of cutting-edge technologies for the technical performance of new materials, scientific and technological workers are constantly striving to improve. In the early 1980s, high-performance and ultra-high-performance carbon fibers appeared one after another. This is another leap in technology, and it also marks that the research and production of carbon fibers have entered an advanced stage.
