In the early 195s, Wright-Patterson Air Force Base in the United States successfully trial-produced carbon fiber from viscose fiber, and the product was used as ablation material for rocket nozzle and nose cone, with good results. In 1956, the United Carbide Company of the United States successfully trial-produced high-modulus viscose-based carbon fiber, and the trade name "Thornel-25" was put on the market. At the same time, the technology of stress graphitization was developed to improve the strength and modulus of carbon fiber.
in p>1879, Edison used cellulose fibers, such as bamboo, flax or cotton yarn, to first make carbon fibers and obtained patents. However, the mechanical properties of the fibers made at that time were very low, and the technology could not be industrialized, which failed to achieve development.
in the early 195s, due to the development of advanced technologies such as rockets, aerospace and aviation, there was an urgent need for new materials with high specific strength, high specific modulus and high temperature resistance. In addition, continuous carbon fiber filaments can be made from precursor fibers by heat treatment, which laid the foundation for carbon fiber industrialization.
