  • Introduction Of The Use Of Carbon Fiber

    The main purpose of carbon fiber is to compound with resin, metall, ceramic and other substrates to make structural materials. Carbon fiber reinforced epoxy resin composite material has the highest comprehensive index of specific strength and specific modulus among the existing structural materials. In areas with strict requirements on density, stiffness, weight, fatigue characteristics, etc., where high temperatures and high chemical stability are required, carbon fiber composites have advantages. Carbon fiber was produced in the early 1950s in response to the needs of cutting-edge science and technology such as rockets, aerospace and aviation. It is also widely used in sports equipment, textiles, chemical machinery and medicine. With the increasingly stringent requirements of cutting-edge technology for the performance of new materials,

  • Introduction To The Characteristics Of Glass Fiber

    Glass fiber is an inorganic non-metallic material with excellent performance. Raw materials and applications Glass fiber has higher temperature resistance than organic fiber, non-combustible, anti-corrosion, good thermal insulation and sound insulation (especially glass wool), high tensile strength and good electrical insulation (such as alkali-free glass fiber). But it is brittle and has poor wear resistance. Glass fiber is mainly used as electrical insulation material, industrial filter material, anti-corrosion, moisture-proof, heat insulation, sound insulation and shock absorption material. It can also be used as a reinforcing material to manufacture reinforced plastics or reinforced rubber, reinforced gypsum and reinforced cement. Covering glass fiber with organic materials can improve its flexibility, and is used to make packaging fabrics, window screens, wall coverings, covering…

  • Performance Characteristics Of Carbon Fiber Materials

    Performance Characteristics Of Carbon Fiber Materials (1) Has good physical and mechanical properties: its tensile strength is more than 10 times that of ordinary steel, and its elastic modulus is equivalent to 1.1 to 2.4 times that of ordinary steel; and the fiber sheet is light in weight and the specific gravity is only 1/4 of the steel ; The thickness is small, the thickness of the general sheet reinforcement layer is between 0.1 ~ 0.2 mm, so basically does not increase the structural cross-sectional size and dead weight. (2) Convenient on-site construction: There is no wet operation and open flame construction, the occupied area is small, and no large-scale construction equipment is required, so the construction is convenient, the…

  • Carbon Fiber Production Method

    At present, industrial production of carbon fiber can be divided into three categories according to the raw material route: polyacrylonitrile (PAN) -based carbon fiber, pitch-based carbon fiber and viscose-based carbon fiber. Carbon fibers made from viscose fibers must be graphitized by high-temperature stretching. The carbonization yield is low, the technology is difficult, the equipment is complicated, and the cost is high. The products are mainly used for ablative materials and heat insulation materials. Carbon fiber is produced from asphalt with rich raw material sources and high carbonization yield. However, due to the complex preparation of raw materials and low product performance, it has not been developed on a large scale. High-performance carbon fibers can be made from polyacrylonitrile fiber precursors. The…

  • Carbon Fiber Development History

    Carbon fiber development history It has been nearly 50 years since China started carbon fiber research and development in the 1960s, but progress has been slow. At the same time, due to decades of technological blockade by developed countries, China has not been able to achieve large-scale industrial production. Demand relies on imports for a long time, which seriously affects the development of China's high technology, especially restricts the development of the aerospace and defense industry, and is extremely disproportionate to China's economic and social development process. Therefore, the development and production of high-performance, high-quality carbon fiber to meet the needs of military and civilian products, to reverse the situation of a large number of imports, is the urgent task…
