As an important applied discipline, textile has the characteristics of multi-discipline cross-convergence and multi-technology cross-border integration, and it is an important carrier of strategic technological innovation. The innovative development of the textile industry is reflected in the emergence of new technologies, new materials, and new products, as well as in the driving effect of new infrastructure, new equipment, and new business formats. It plays an irreplaceable role in improving the national innovation system and building a technological power. effect.
High-performance fibers and their composites represented by carbon fiber and aramid are the key basic materials for the national high-tech industry. They are continuously promoting high-speed trains and other rail transit, new energy vehicles and charging piles, UHV transmission lines and other emerging industries and new types Technological progress and industrial upgrading of infrastructure.
In September 2018, at the International Rail Transit Technology Exhibition in Berlin, Germany, CRRC Qingdao Sifang Locomotive and Rolling Stock Co., Ltd. officially released the new generation of carbon fiber subway “CETROVO”, which realized that the driver’s cab, car body, and equipment compartment were compared with the original metal materials. The weight is reduced by about 30%, and the weight of the bogie is reduced by 40% compared with the original metal material. It is a model of large-scale application of carbon fiber composite materials on rail vehicles so far. At present, CETROVO has completed the line test and operation demonstration, and successfully passed the acceptance.
In December 2019, the world’s first “Inner Mongolia Ximeng-Shandong” UHV supporting project with a full line of carbon fiber composite core conductors-the 1000 kV transmission line of Datang Xilinhot Power Plant was officially connected to the grid and put into operation in Inner Mongolia. This project line It has a total length of 14.6km and is erected with a single circuit. The line uses a carbon fiber composite core conductor independently developed by China. The commissioning of this line not only saves energy and reduces operating costs, it can also increase the transmission power of 1.32 million kW·h every year, alleviating the shortage of electricity in North China.
In addition, high-performance fibers and their composite materials can also be seen on new energy vehicles and charging piles. New energy vehicles use electricity as a source of driving power, and need to consider issues such as circuit short-circuit or high-voltage breakdown. Therefore, in addition to insulation voltage resistance and corrosion resistance, flame retardancy needs to be considered in the selection of materials. Therefore, carbon fiber reinforced composite materials, long glass fiber flame-retardant reinforced polypropylene materials, and PP reinforced composite materials (PPLGF35) have become the primary choice for battery module housings.
