Development of New Composite Materials in China
China has great potential for the development of composite materials, but the following hot issues must be dealt.
Composites Innovation
The innovation of composite materials includes the technological development of composite materials, the process development of composite materials, the product development of composite materials and the application of composite materials. Specifically, we should grasp the development and innovation of resin matrix, the development and innovation of reinforcement materials, the development and innovation of production process and the development and innovation of product application. By 2007, the proportion of Asia in the world's total sales of composite materials will increase from 18% to 25%, and the per capita consumption in Asia is only 0.29kg, compared with 6.8kg in the United States. Asia has great growth potential.
Development of Polyacrylonitrile-based Fibers
China's carbon fiber industry is developing slowly. From the review of CF development, characteristics, domestic carbon fiber development process, China's PAN-based CF market overview, characteristics, and "Tenth Five-Year Plan" scientific and technological research, it is both necessary and possible to develop PAN-based fibers.
Adjustment of glass fiber structure
More than 70% of China's glass fiber is used to strengthen the substrate, which has a cost advantage in the international market, but there is still a gap between China and advanced countries in terms of variety, specification and quality. It is necessary to improve and develop yarn, woven fabric, non-woven felt, braided fabric and composite felt, promote close cooperation between glass fiber and glass steel industries, and promote the new development of glass fiber reinforced materials.
Development of composite materials market for energy and transportation
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, Including car body, frame and car body outer cover, rail transit car 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. China will need to add 661 regional aircraft in the next 20 years, which will form a large industry of civil aviation passenger aircraft, and composite materials can be built into new industries to match it. Fourth, composite materials for boats, mainly yachts and fishing boats, have a large market in Europe and the United States as high-end entertainment durable consumer goods. Due to the reduction of fish resources in China and the slow development of fishing boats, there is still room for development due to the unique advantages of composite materials.
