Faced with the outstanding performance of my country's FRP/composite material output of 940,000 tons last year, there is still great potential for further accelerated development of FRP, but seven hot issues must be properly dealt with.
Composites Innovation. Composite materials themselves are the product of human technological innovation. Composite material innovation includes the technical development of composite materials, the process development of composite materials, the product development of composite materials and the application of composite materials. Specifically, it is necessary to grasp the development and innovation of resin matrix, the development and innovation of reinforced materials, the development and innovation of production technology, and the development and innovation of product application. And application development must be innovative. By 2007, Asia's share of the world's total sales of composite materials will increase from 18% to 25%. At present, the per capita consumption in Asia is only 0.29 kg, while that in the United States is 6.8 kg. Asia, including China, has great growth potential.
Development of polyacrylonitrile-based fibers. The development of my country's carbon fiber industry 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 "Tenth Five-Year Plan" scientific and technological breakthroughs, it is necessary and possible to develop polyacrylonitrile-based fibers.
Glass fiber hair structure adjustment. More than 70% of my country's glass fiber is used to reinforce the base material, which has a cost advantage in the international market, but there is still a gap with advanced countries in terms of variety, specification and quality. It is necessary to improve and develop yarns, woven fabrics, non-woven felts, and braided fabrics. , stitched fabrics, and composite mats, promote close cooperation between the glass fiber and glass steel industries, and promote the new development of glass fiber reinforced materials.
Develop energy and transportation composite materials markets. The first is 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; the second is composite materials for automobiles and urban rail transit Materials, including automobile body, frame and body cover, rail transit body, door, seat, cable duct, cable rack, grille, electrical box, etc.; the third is composite materials for civil aviation aircraft, mainly carbon fiber composite materials, Thermoplastic composite materials account for about 10%, and the main products are wing parts, vertical tail fins, nose covers, etc. China will need to add 661 new regional aircraft in the next 20 years, which will form a large industry of civil aviation airliners. Composite materials can be built into new industries and The fourth is composite materials for boats, mainly yachts and fishing boats. Yachts, as high-end entertainment and durable consumer goods, have a large market in Europe and the United States. Although fishing boats are slow in development due to the reduction of fish resources in China, due to the unique advantages of composite There is still room.
Fiber composite infrastructure applications. Composite materials at home and abroad are widely used in bridges, houses, and roads. Compared with traditional materials, composite materials have many advantages, especially in bridges, building reinforcement, tunnel engineering, and large storage warehouse repair and reinforcement.
Comprehensive processing and regeneration of composite materials. Focus on the development of physical recovery - crushing recovery, chemical recovery - thermal cracking and energy recovery, strengthen technical routes, comprehensive treatment technology research, demonstration production line construction, recycling research, and vigorously expand the application of recycled materials in gypsum and pultrusion Application in products, application in SMC/BMC molded products and application in typical products.
Strengthen quality management. Overcome geometric appearance problems, insufficient product rigidity, insufficient deflection resistance, connection problems, insufficient tensile strength, leakage and sweating by improving management, raw material quality, structural design, manufacturing equipment and process technology, construction monitoring, etc. and size problems, establish a sound quality inspection system for FRP pipes and raw materials, and strengthen the renewal and transformation of winding equipment.
