The development of composite materials has brought tremendous development opportunities for China's industrial textile industry. Because the reinforcement of the composite material is a textile material, including non-woven fabrics, axial knit fabrics, woven fabrics, and woven fabrics. During the “Twelfth Five-Year Plan†period, China's composite materials will maintain a growth rate of 9% per year. By 2015, composite materials production will reach 6 million tons, of which 4 million tons will be textile materials. Among them, the amount of building reinforcement and repair composite materials reached 100,000 tons, the amount of composite materials for railways was 1 million tons, the composite materials for automobiles were 2 million tons, and the composite materials for marine basic engineering were 1 million tons. It is 1 million tons and the aerospace composite is 800,000 tons.
We need to focus on several application areas of composite materials. First, the use of composite materials on yachts. In the next few years, the Chinese yacht market is vast. With the increasing demand from yacht clubs, real estate developers, waterfront companies and the middle class, China will have 100,000 yacht purchases in the next 5 to 10 years, which will be a huge amount of 50 billion to 100 billion yuan. market.
Second, the compound annual growth rate of wind power installed capacity in the Chinese market will reach 32.3%, which is higher than the global average of 22.8%. According to the "China Wind Power Development Report 2010" forecast, the cumulative installed capacity of China's wind power in 2020 can reach 230 million kilowatts. The low-power wind turbine blades mainly adopt glass fiber reinforcement materials, and the high-power generator blade parts adopt carbon fiber composite materials, and the future carbon fibers are promising.
Third, during the “Twelfth Five-Year Plan†period, the development goal of spacecraft materials was to reduce the structural weight. The selection of materials for the use of high-performance materials, such as ultra-high modulus carbon fiber and the corresponding resin body materials, can improve the life of the satellite.
Most of the reinforcements of composite materials use glass fiber, carbon fiber, etc., which requires us to continuously improve the weaving technology of glass fiber, carbon fiber and the like.
