"Xiang" carbon fiber composites upgrade power delivery equipment - clever design of new technology double-cost reduction - according to
China Coatings Onlineexperts
The 16 trains running on Line 2 of Changsha Metro, the carbon fiber-reinforced resin-based composite foam core structure used in their heads, can lose 35% weight while increasing their strength, and shorten the production cycle to two-thirds of the original fiberglass driver's table. This is one of the achievements of the key technology research and industrialization of carbon fiber composite materials for power transmission equipment, which is led by the National Defense University of Science and Technology. On March 18, the special project passed the expert acceptance organized by the provincial science and technology department.
resin-based composite material is characterized by light weight, high strength and strong designability. Carbon fiber composite material is the leader in resin-based composite materials, than strength (strength/density) is high-strength steel, aluminum alloy and other traditional metal materials 2 to 3 times, so that there is "softer than hair, harder than steel" said. Although carbon fiber composite materials in rail transportation, wind power equipment and many other fields have broad application prospects, but because of the high cost of materials and process costs, generally used in the aerospace field. Under the leadership of the chief expert, Professor XiaoGayu of National Defense University of Science and Technology, the project team designed the benefits by optimizing.
more than 50% of China's land wind resources belong to low wind speed resources, in order to capture more wind energy, we must lengthat the blades. The application of special technology, the new material of the times in China took the lead in the preparation of a thick 40mm, width 500mm, 40m long large-scale composite wind blade main beam, so that the same model of blade total weight reduction of 30%. Compared with similar carbon fiber blades in the world, the total cost of carbon fiber blades decreased by about 16% under the premise of comparable performance. At present, the maximum size of wind blades mass produced by new materials in the era has reached 59.5 meters. During the implementation of the project, related composite materials delivery products in China's 8 large-scale wind farms, 5 subway lines and 2 provincial high-voltage transmission lines have been applied, 3 years of cumulative sales revenue of more than 2.4 billion yuan, the realization of profits and taxes of more than 600 million yuan.。
