Carbon fiber is a high tenacity and high tenacity chemical fiber with a carbon content of more than 90%. Heat resistance ranks first among all chemical fibers. It is made of nylon and viscose fibers as raw materials, which are oxidized and carbonized by high-temperature air. It is a high-quality material for manufacturing high-tech equipment such as aerospace. It has the characteristics of heat resistance, friction resistance, electrical conductivity, heat transfer and corrosion resistance. The appearance design is fibrous, soft, and can be produced and processed into various textiles, because its high-purity graphite nanocrystalline structure is preferably oriented along the chemical fiber axis Therefore, it has high compressive strength and strain rate along the chemical fiber axis.
The carbon fiber that everyone often refers to is actually a generic term for carbon fiber reinforced composite materials. The forming process of carbon fiber-enhanced composite materials is divided into three key steps: forming, drying and molding. Early preparations include: pre-preparation of mold shells, adhesive configuration, and pre-preparation of carbon fiber textiles. Everyone says that carbon fiber is very expensive. In fact, it refers to the high price of parts and components produced and processed by using carbon fiber to improve composite material raw materials. The high cost is due to the high cost of materials and processing technology.
Everyone often hears about carbon fiber, that is, it is a kind of material with excellent performance. It not only has the original characteristics of hard carbon material, but also has the production and processing characteristics of textile chemical fiber. It is called the first material. High-grade materials often used in airports, rockets, and bulletproof vehicles. The first use of carbon fiber in cars was in F1 sports cars. Nowadays, it is also used on civilian cars. It is painted with red paint and has carbon fiber parts that accidentally exposed gray and black woven patterns. It is cool when it is opened.
Carbon fiber has many high-quality characteristics. Carbon fiber has high axial compressive strength and strain rate, low relative density, high specificity, no stress relaxation, high temperature and high pressure resistance under non-air oxidation natural environment, good fatigue resistance, constant pressure specific heat and The conductivity is close to the middle of non-metallic materials and metal materials, the linear expansion coefficient is small and various, the corrosion resistance is good, and the X-ray passability is good. Excellent electrical conductivity, heat transfer performance, good magnetic shielding material properties, etc. Compared with the traditional glass fiber, the Young's modulus of carbon fiber is more than three times that of it; compared with Kevlar fiber, the Young's modulus is about twice as much as that of carbon fiber. Sexually prominent.
