China has become the largest application market for fiber-reinforced composite materials in the world, and innovation in composite materials is a trend in the future. "Fiber-reinforced composite materials are not only key materials in the field of high-tech and cutting-edge technologies, but also important materials in the fields of upgrading of automobiles, new energy, new building materials, information industry, petrochemicals, and environmental protection, and industrial upgrading. The world faces an energy crisis and With the shortage of resources, fiber-reinforced composite materials usher in new opportunities for development.†At the 19th China International Composites Industry and Technology Exhibition recently held in Beijing, Jin Qiu Beijing, exhibitors of domestic and foreign enterprises talked about the new materials industry and issued As above forecast.

As the leader of special high-performance synthetic fibers, carbon fiber is the fastest growing in the world. Because it has similar characteristics to traditional reinforcing fibers, it has been used in high-end fields. Over the years, overseas carbon fiber manufacturers have been optimistic about China's continued growth in the market. This exhibition, the world-famous carbon fiber manufacturers Toray, Toho, Mitsubishi, Zoltek, Hearst, SGL, Formosa Plastics, Hyosung, etc. Companies have demonstrated high-performance carbon fibers, prepregs and products with their own characteristics. The Turkish company DOWAKSA, which is active in the global carbon fiber market, is the world's largest manufacturer of polyacrylonitrile and carbon fiber. It entered the show for the first time this year. It is understood that in 2012, its sales in China were more than 1,500 tons. Zhao Honghan, deputy secretary-general of the China Unsaturated Polyester Resin Industry Association, pointed out that when lightweight design of FRP meets the limits of its own material properties, the sandwich structure and nano-materials will greatly change the original mechanical performance system.
He said that over the years, China's carbon fiber development has become a bottleneck in the development of domestic carbon fiber composite materials, forming a restricted pattern of imported carbon fiber and domestic deep processing. To catch up with the pace of global carbon fiber development, more than 30 companies across the country are currently engaged in R&D and application, and have formed carbon fiber processing and manufacturing bases in Dalian, Weihai, Lianyungang, Harbin, Yixing, Dongguan, Ningbo, Beijing and Shanghai. According to relevant data, in 2012, the global carbon fiber demand was around 60,000 tons, with a production capacity of 100,000 tons, and China’s demand was 6,000 tons. An information agency predicts that by 12% growth rate will reach 80,000 tons by 2020. Other high-performance fibers exhibited at the show include DSM, a global manufacturer of aramid fibers, and DSM, a manufacturer of UHMWPE. At this composite exhibition, there were also some ultra-thin and ultra-light composite samples. The sound of tapping was as crisp as steel. “Lightweight design and lightweight materials are the highlights of every exhibition. At this exhibition, Chinese and foreign companies launched dozens of lightweight structural materials, including aluminum honeycomb, aramid honeycomb, paper honeycomb, Balsa balsa, 3D fiberglass fabrics, all kinds of closed-cell structural foam, etc.. Zhao Honghan said that taking high-speed trains in Europe as an example, a large number of 3D-woven phenolic foam structures are used for inner wall cores. The composite innovation of traditional materials, the promotion of application level and wider application are the future development trends.
According to relevant sources, the foam sandwich structure is being developed toward micropores, high strength, ultra-thin, and low oil absorption. Hebei Dedong New Energy Automobile Co., Ltd. for the first time exhibited and tried to develop lightweight vehicles and accessories for new energy sources. The company has designed an annual production capacity of 200,000 electric vehicles and introduced a German composite material production line, which will produce a variety of lightweight auto parts for the market. "Everything is ready, and only the east wind is owed." This is a common exclamation of many exhibitors and visitors. "Everything is ready" reflects that China has become the world's largest market for fiber-reinforced composite materials, with fiberglass composites accounting for 99% of the country's total; the country's economic transformation and upgrading has made an order to speed up the development of new materials industries, and the glass fiber reinforced plastics have been Large-scale entry into the civil industry has played an important role in light and high-strength, energy-saving emission reduction, energy development, green construction, and industrial environmental protection; FRP composite materials have experienced 50 years of application development history in China. Many experts at the show stated that "Only owes the east wind" is to describe the lag of our design and innovation. A large number of small and medium-sized glass steel enterprises lack specialized technical personnel, and there is a shortage of material mechanics and mechanical and electrical professionals. Enterprises cannot form a market-oriented, high-profile technology development team. Some technical leaders of exhibitors said that in the face of the current good opportunity, while promoting high-quality materials, we must vigorously carry out design, technology, standards, and applications to enter the company, enter the market, and realize the midstream and downstream of FRP composite materials. Through close integration and interaction, the entire industry transitions from extensive to intensive.
