The main use of carbon fibers is to make structural materials by compounding with resins, metals, ceramics and other substrates. Carbon fiber reinforced epoxy resin composites have the highest specific strength and modulus among the existing structural materials. Carbon fibre composites have many advantages in the fields of density, stiffness, weight, fatigue properties and high temperature and chemical stability. Carbon fibers were produced in the early 1950s in response to the needs of advanced science and technology such as rockets, aerospace and aviation, and are now widely used in sports equipment.
Carbon fibers, known as polyacrylonitrile-based carbon fibers, are made from carbon fibers and related matrix resins, such as epoxy resins. Carbon fibers are a special kind of fibers mainly composed of carbon elements. The carbon content of carbon fibers varies with different kinds, generally more than 90%. Carbon fibers have the characteristics of general carbon materials, such as high temperature resistance, friction resistance, electrical conductivity, heat conductivity and corrosion resistance. But unlike ordinary carbon materials, carbon fibers have remarkable anisotropy, softness, and can be processed into various fabrics, showing high strength along the fiber axis. Carbon fibers have high specific strength because of their low specific gravity.
From the high-end aerospace applications to the daily civil technology fields, CFRP not only fully demonstrates the unique characteristics of high strength and light weight of CFRP, but also has the designability of composite materials, which to a certain extent meets the application requirements of lightweight in different fields. Following is a brief introduction to the application of carbon fiber composites in different fields, aiming at the specific application form of box. The G0Vision LED of America is the first manufacturer to apply carbon fiber composite material to the LED display case.
China Securities Daily, Oct. 14, reported that the General Administration of Customs will vigorously promote the innovative development of new business in the Shanghai Free Trade Experimental Zone, such as promoting the development of futures bonded delivery business, in its "Measures to Support and Promote the Construction of China (Shanghai) Free Trade Experimental Zone". Reporters recently learned that the Shanghai Free Trade Pilot Zone may launch a pilot delivery warehouse for overseas futures exchanges, while Shanghai Port is expected to replace Busan as the largest delivery port for copper futures in East Asia.
