Carbon fiber is a new type of high-strength and high-modulus fiber material containing more than 95% carbon. It has excellent comprehensive properties: low density, high tensile strength, good corrosion resistance, low thermal expansion coefficient and outstanding fatigue resistance. Compared with traditional metal materials like steel and aluminum alloy, carbon fiber composite parts can reduce weight greatly while maintaining or even improving structural strength. Carbon fiber products are commonly made into carbon fiber reinforced polymer composites (CFRP) by combining with resin matrix. The main grades include T300, T700, T800, T1100, which differ in tensile strength and modulus for different usage scenarios. Main application fields:
Aerospace & aviation: aircraft structural parts, drone frames, satellite components to reduce aircraft weight and save fuel consumption.
2. Automotive industry: carbon fiber body panels, automotive molds, racing parts, new energy vehicle lightweight components. 3. Sports & leisure: carbon fiber bicycle frames, paddle boards, fishing rods, rackets and golf clubs. 4. Industrial equipment: robot arms, medical equipment parts, pressure vessels, wind turbine blades. 5. Construction: building reinforcement and seismic reinforcement projects. Although carbon fiber has remarkable advantages, it also has limitations. Its production cost is relatively high, and the material is brittle with poor impact resistance. So it needs reasonable structural design and proper matrix matching to achieve the best performance. With the continuous development of manufacturing technology, carbon fiber is gradually expanding into more civilian markets.
