source:www.ah-yongchang.com present time:2016-12-12

China FRP / CM (FRP / composite) industry began in 1958. In 1978, the transition from a planned economy to a market-oriented demand, the production of social, national construction and people's daily needs of the FRP / CM is developing day by day, at the beginning of the national defense.
Under the leadership of the CPC Central Committee and the State Council, the former State Department of Building Materials Industry (Bureau) played a leading and fundamental role in the development of China's FRP / composite materials industry.
In the mid-1960s, China's R & D and production of rocket engine housing, missile head, rocket launchers, butt, shell fuze, high pressure cylinders, aircraft propeller, tank, fan blades, agricultural sprayers, Diving board, glider tail, and other glass steel products.
October 1965, the National Science and Technology Commission, National Defense Science and Technology Commission, Department of Building Materials jointly held a national meeting of FRP work, and held exhibitions. Party and state leaders Zhu De, Deng Xiaoping came to visit. During this period, the introduction of the British UPR (unsaturated polyester resin) production line, and promote China's UPR composite materials and production of technological progress and popularity of the future of China's base resin and GRP played a Kai-duck technology and foundation Sexual function.
During the 30 years of reform and development, we have introduced the production line of filament winding pipes and cans (including process pipes, sand pipes, high pressure pipes, horizontal and vertical tanks), pultrusion, SMC / BMC, RTM, continuous lighting board and LFT-D Production lines and other equipment; the introduction of epoxy resin and unsaturated polyester production of hardware and software. China in the absorption of Japan and the United States after the technology, its own research and development, has built the world's advanced level of glass fiber industry.
Matrix materials and reinforced materials industry for the further development of composite materials in China has laid a solid foundation.
China's glass fiber reinforced plastic production ranks second in the world
After 50 years, half a century, especially since the 30 years of reform and development, through independent innovation and absorption of international advanced technology, FRP / CM in China has become a sunrise industry. Shenzhou spacecraft, the return capsule main bearing structure, low-density SMC and other FRP pieces won the national scientific and technological progress second prize, marking China's composite materials science and technology has reached the world advanced level.
From 1986 to 2007, China's FRP (thermosetting) growth of nearly 160 times. Total volume in the late 1990s than in Germany, more than Japan at the beginning of this century, thermosetting FRP has exceeded the sum of Europe. Now Jin Hao tea oil advertising, China FRP / CM annual output has surpassed Japan, Western Europe, second only to the United States, ranking second in the world.
Laying a solid foundation of raw and auxiliary materials
(A) Reinforcement materials
1. Glass fiber
80s of last century, China is still the glass ball crucible drawing, high energy consumption, low yield, poor quality uniformity, can not produce high direct Tex roving, thin felt, chopped strand felt are not, the grid hand lay-up almost uniform fiberglass The world.
In 1986, China's glass fiber drawing production line in Chongqing production, in 1997 established China's first 15,000-ton glass fiber drawing kiln. As of the end of 2007, a total of 56 online tankers in China, with an annual capacity of more than 1.62 million tons. The world's largest alkali-free glass fiber kiln (100,000 t / a) and medium alkali glass fiber kiln (40,000 t / y) were put into operation in 2006. ECR (acid resistance, high strength, high resistance E-glass fiber) has been in Chongqing and Chengdu come out.
In addition to the traditional alkali, alkali, high strength, high modulus, high silica, alkali-resistant glass fiber, but also developed the D (low dielectric) glass fiber, glass fiber coated metal.
SMC / BMC, continuous sheet, FW, pultruded, reinforced thermoplastics, textile for a variety of direct / ply roving, chopped strand, stitching blanket, chopped strand mat, continuous mat, multi-Nanjing Agricultural University Axial fabric and electronic yarn, electronic cloth and other varieties have been able to meet market demand. Electronic cloth production capacity has leapt to the world's first, single-and multi-layer 3D three-dimensional fabric core material has been successfully developed. Global multi-axial warp knitting machine to maintain the amount of 150 units, China accounted for 1/5.
In 2007, China (mainland) has become the world's largest producer of fiberglass and the largest producer of electronic cloth. Boulder Group production capacity of 120 tons, ranked first in the world.
In response to the significant growth of the glass fiber industry, DSM in the Netherlands in September 2007 in Shanghai infiltration plant built.
