"Throughout the development history of rail transit, we can see that in the rail transit system, whether fixed facilities or mobile equipment, every technological innovation or technological progress takes the change of materials or processes as an opportunity." Zhu Hequan, a researcher at the Institute of metals and chemistry of the Chinese Academy of Railway Sciences, said a few days ago. In recent years, the rapid rise of high speed rail and city rail transit has opened up a new world for non-metallic chemical materials, especially lightweight glass fiber reinforced plastics. The established investment and development goals of the 12th Five-Year have laid a good market expectation foundation.
In recent 10 years, the development of China's high-speed railway industry has attracted global attention. According to the 12th Five Year Plan for comprehensive transportation system recently issued by the State Council, China will connect the "four vertical and four horizontal" high-speed railway network and build relevant auxiliary lines, extension lines and connecting lines in 2015. During the 12th Five Year Plan period, the scale of railway fixed asset investment is 2.8 trillion yuan, of which 2.3 trillion yuan is capital construction investment and 0.5 trillion yuan is equipment investment.
China's high-speed rail market is an area that makes the world's rail investment and developers * * yearn for. The plan previously announced by the Ministry of Railways shows that 2013 will be more than one year after the new railway line is put into operation * *, with a total mileage of 6366 kilometers, 55% of which are high-speed rail lines, and the "four vertical" high-speed rail trunk lines along the sea in Beijing Shanghai, Beijing Shenzhen, Beijing Harbin and Southeast China will be basically formed.
Moreover, subway, light rail, suburban railway, tram and other types of urban rail transit across the country have become the real transportation aorta of cities. So far, the state has approved the network planning and construction planning of 36 cities, with a total mileage of 5790 kilometers, and approved the feasibility study reports of some projects in 28 cities. It is estimated that during the 12th Five Year Plan period, China's urban rail transit will continue to maintain the trend of rapid development, with an investment of more than 1 trillion yuan and a new mileage of about 1600 kilometers, exceeding the total mileage put into operation in the past 40 years (1455 kilometers). It is estimated that by the end of 2015, the total operating mileage of urban rail transit in China will reach about 3000 kilometers.
Industry experts pointed out that China's urban rail transit is a systematic project, involving all fields of the industry. Its scope covers locomotives, vehicles and parts, vehicle interior decoration, rail transit transportation and management technology, infrastructure and electromechanical equipment, construction materials for urban rail transit construction, equipment, safety, energy conservation, environmental protection technology and maintenance, planning, design, consulting Supervision services, engineering construction machinery and equipment and supporting facilities, "generally speaking, it comes down to tunnel engineering, track engineering and vehicle body movement engineering. These three projects have gathered domestic * * enterprises and attracted the participation and cooperation of * * enterprises from Germany, France, Italy, Austria, Sweden, Switzerland and other countries and regions."
Zhao Honghan, Deputy Secretary General of China Unsaturated Polyester Resin Industry Association, believes that China's high-speed railway has reached 350 kilometers per hour. To promote the rapid operation of high-speed railway trains, lightweight materials have become an important part. "Among the three lightweight materials, FRP has become the main material of interior structural parts. At present, it has formed modular series products, bus seat series products, toilet series products, bridge and cab interior decoration series products, sound screen sound insulation series products and export parts series products."
