June 2, 2009: the development of modern high technology is inseparable from composite materials. Composite materials have a very recyclable iron and steel process technology to improve the efficiency of resource and energy utilization and emission reduction for the development of modern science and technology; Ecological non blast furnace ironmaking technology plays an important role. The research depth, application breadth, production development speed and scale of composite materials have become one of the important symbols to measure the advanced level of a country's science and technology. It can be expected that with the continuous maturity and development of advanced high-performance resin composites, the practicality of metal matrix, especially intermetallic compound matrix composites and ceramic matrix composites, and the development of micro scale nanocomposites and molecular composites, composite materials will become more and more important in human life. The 21st century will be a new era of composite materials. The development potential of composite materials in China is great, and the innovation of composite materials is imminent. The innovation mainly includes the technical development of composite materials, known as strength testing machine, tensile testing machine and universal testing machine, the process development of composite materials, the product development of composite materials and the application of composite materials. Specifically, we should focus on the development and innovation of resin matrix, reinforcement materials Development and innovation of production process and product application. The global composite material market is growing rapidly, and the composite material market in Asia, especially in China and India, is growing rapidly. From 2003 to 2008, the average annual growth rate of composite material demand in China was 9.5%; It is 15% in India and only 4% in Europe and North America. At present, the output of composite materials in the global market is about 8.2 million tons, and China accounts for 16%. With the rapid development of China's composite industry, the four bright spots "shine" on the whole industry

on the basis of the continuous development of the whole industry, the development of polyacrylonitrile based fibers deserves special attention. The development of carbon fiber industry in China is slow. From the review and characteristics of CF development, the development process of domestic carbon fiber, the overview and characteristics of China's Pan Based CF market, and the situation of tackling key scientific and technological problems in the tenth five year plan, it is both necessary and possible to develop polyacrylonitrile based fiber. Composite materials for energy and transportation are also "good": first, composite materials for clean and renewable energy, including composite materials for wind power generation, composite materials for flue gas desulfurization devices, composite materials for power transmission and transformation equipment, and high-pressure containers for natural gas and hydrogen; Second, composite materials for automobile and urban rail transit, including automobile body, frame and outer covering parts of car body, rail transit body, door, seat, cable trough, cable rack, grille, electrical box, etc; Third, composite materials for civil aircraft, mainly carbon fiber composite materials. Thermoplastic composite materials account for about 10%, and the main products are wing components, vertical tail, nose cover, etc. In the next 20 years, China will need to add 661 regional aircrafts, which will form a large industry of civil aircraft, and composite materials can be built into a new industry to match it; Fourth, composite materials for boats and boats are mainly yachts and fishing boats. Yachts, as high-grade entertainment durable consumer goods, have a large market in Europe and America. Due to the reduction of fish resources in China and the slow development of fishing boats, there is still room for development of the unique advantages of composite materials

fiber composite infrastructure application continues to be a highlight due to its wide application in bridges, houses and roads at home and abroad. Compared with traditional materials, composite materials have many advantages. Composite materials have a broad market in the basic field, especially in bridges, building reinforcement, tunnel engineering and large-scale warehouse repair and reinforcement. In the future, China's infrastructure will have a broad space for development. On the whole, the construction of infrastructure is still in its infancy, and the existing problems are still prominent: the investment in agricultural infrastructure construction is obviously insufficient; Unbalanced development of transportation energy construction; Urban infrastructure construction is still lagging behind. The demand for fiber composites will increase. The comprehensive treatment and regeneration of composite materials will become a new sub industry. The development of this industry will focus on physical recovery (crushing recovery), chemical recovery (thermal cracking) and energy recovery, strengthen the research on technical route and comprehensive treatment technology, the construction of demonstration production line, research on recycling, expand the application of recycled materials in gypsum, pultrusion products, and smc/bmc molded products, New progress news is constantly coming out. As long as the Taiwan factory has mastered the key technology, the enterprise level applied in typical products is not poor; The development of this field also involves the formulation of industry standards with guiding significance and the introduction of environmental protection policies. Enterprises should measure the competitiveness of the enterprise market from the core strength that it is sometimes difficult for enterprises to judge the limitations and shortcomings of materials, such as whether they comply with domestic and foreign environmental protection standards, design and R & D strength, etc
