Development of composite materials for industrial use in China textile The industry has brought tremendous opportunities for development. Because the reinforcements of composite materials are textile materials, including non-woven fabrics, axial knitted fabrics, woven fabrics and knitted fabrics. " The 12th Five-Year During the period, China's composite materials will maintain an annual growth rate of 9%. By 2015, the output of composite materials will reach 6 million tons, of which 4 million tons will be textile materials. Among them, the amount of composite material used for building reinforcement and repair reaches 100 thousand tons, and the composite material for railway is 1 million tons. Material Science For 2 million tons, composite materials for marine foundation engineering are 1 million tons, composite materials for the electric power industry are 1 million tons, and aerospace composite materials are 800 thousand tons.

We need to pay attention to several applications of composite materials. First, the use of composite materials on yachts. In the coming years, China's yacht market is vast. As demand for yacht clubs, real estate developers, waterfront enterprises and middle class groups increases, China will have 100 thousand yacht purchases in the next 5 to 10 years, and will be a huge market from 50 billion yuan to 100 billion yuan.

Second, the composite annual growth rate of wind power installed capacity in the Chinese market will reach 32.3%, higher than the global average of 22.8%. According to the report of China Wind Power Development Report 2010, the cumulative installed capacity of China's wind power in 2020 can reach 230 million kilowatts. Small power wind turbine blades are mainly reinforced with glass fiber, and the blades of high-power generators are made of carbon fiber composite materials. fibre Have a brilliant future.

Third, during the "12th Five-Year" period, the development goal of spacecraft materials is to reduce structural weight. High performance materials, such as ultra-high modulus carbon fiber and corresponding resin material, can improve the service life of satellites.

Most of the reinforcements of composites are made of glass fiber, carbon fiber and so on, which requires us to continuously improve the weaving technology of glass fiber and carbon fiber.
