Carbon fiber composites (or CF, graphite or graphite fibers) are fibers with a diameter of about 5-10 microns, which are basically composed of carbon atoms. Carbon fiber has several advantages, including high stiffness, high tensile strength, low weight, high chemical resistance, high temperature resistance and low thermal expansion. These properties make carbon fiber very popular in aerospace, civil engineering, military and automotive sports and other competitive sports. However, they are relatively expensive compared to similar fibers, such as glass fiber or plastic fiber, and their properties cannot be compared with carbon fiber.
In order to produce carbon fiber boards, carbon atoms are combined in a crystal arranged roughly parallel to the long axis of the fiber, because the crystal arrangement gives the fiber a high strength volume ratio (making it very large in size). Carbon fiber bundles are bundled together to form tow, which can be used alone or woven into fabrics. Generally speaking, carbon fiber fabric is called carbon fiber cloth, which is widely used in engineering construction. #nbsp;
Carbon fibers are usually combined with other materials to form composites. When impregnated and baked with a plastic resin, it forms a carbon fiber reinforced polymer (commonly known as carbon fiber), which has a very high strength to weight ratio, although somewhat brittle, but very hard. Carbon fiber is also a kind of reinforced carbon carbon composite with high heat resistance. Carbon;
The carbon fiber board consists of thousands of consecutive individual strands of carbon fibers protected by organic coatings or sizes, such as polyethylene oxide (PEO) or polyvinyl alcohol (PVA). The tow can be easily deployed from the reel. Each carbon wire in the tow is a continuous cylinder with a diameter of 5-10 microns, which is almost entirely composed of carbon. The earliest generation (e.g. T300, HTA and AS4) was 16-22 microns in diameter. Fibers (e.g., im6 or im600) have a diameter of about 5 microns.
Carbon fiber boards are most prominently used in reinforced composites, especially those called carbon fibers or graphite reinforced polymers. Non polymer materials can also be used as matrix of carbon fiber. Due to the formation and corrosion of metal carbides, the application of carbon in metal matrix composites has achieved limited success. Reinforced carbon carbon (RCC) consists of carbon fiber reinforced graphite and is structurally used for high temperature applications. The fiber can also be used to filter high-temperature gases, as an electrode with high surface area and impeccable corrosion resistance, and as an antistatic component. Molded thin carbon fiber layers can significantly improve the fire resistance of polymers or thermosetting composites because dense, dense carbon fiber layers effectively reflect heat. Carbon fiber composites are used in more and more industries and enterprises.
