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. During the "12th Five-Year" period, China's composite materials will maintain an annual growth rate of 9%, to 2015 composite materials. yield It will reach 6 million tons, of which 4 million tons are textile materials. Among them, the amount of composite materials used for building reinforcement and repair reaches 100 thousand tons, the railway composite material is 1 million tons, the automobile composite material is 2 million tons, the marine foundation engineering composite material is 1 million tons, the electric power industry uses the composite material 1 million tons, and the aerospace composite material is 800 thousand tons.

We need to pay attention to several composite materials. application Field. First, the use of composite materials on yachts. In the next few years, China's yacht market is vast. With yacht clubs, real estate developers, waterfront businesses and middle class buying groups, etc. demand China will have 100 thousand yachts in the next 5 to 10 years. Purchase The amount will be $50 billion to $100 billion. market 。

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 made of glass fiber reinforced materials. The blades of high-power generators are made of carbon fiber composite materials.

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.
