Why add graphite powder to glass fiber?

Glass fiber enhanced plastic (FRP) is a composite composite material based on synthetic resin. It has the advantages of light weight, high strength, corrosion resistance, microwave transmission, electrical insulation, and reasonable performance design according to requirements. It has been widely used in aerospace, petrochemicals, transportation, construction, shipbuilding, machinery, environmental protection, textile and other fields. Glass fiber enhanced plastic (FRP) has good electrical insulation property. Under normal circumstances, the amount of graphite powder is 2.5 ~ 5%, which can reach 30 ~ 50%. So why add graphite powder to glass fiber?From an economic and technological perspective, it is best to choose inorganic abrasive materials, so the amount of graphite powder in the abrasion -resistant material of the glass fiber reinforcement is relatively large. In short, glass fiber wear -resistant materials, because its matrix is a polymer material, fills solid lubricants and vari

Carbon and graphite products

（1） Graphite electrodes are mainly made from petroleum coke and needle coke as raw materials, and coal tar pitch as a binder. They are made by calcination, batching, kneading, pressing, roasting, graphitization, and machining. They are conductors that release electrical energy in the form of an arc in an electric arc furnace to heat and melt the furnace material. According to their quality indicators, they can be divided into ordinary power, high power, and ultra-high power. Graphite electrodes include:(1) Ordinary power graphite electrode. Allowing the use of graphite electrodes with a current density below 17A/cm2, mainly used for ordinary power electric furnaces such as steelmaking, silicon smelting, and yellow phosphorus smelting.(2) Anti oxidation coated graphite electrode. A graphite electrode coated with an antioxidant protective layer on the surface forms a protective layer that is both conductive and resistant to high-temperature oxidation, reducing electrode consumption duri

The position and role of carbon industry in the development of the national economy

Compared with large industries such as machinery, automobiles, electronics and electrical engineering, mining and metallurgy, railways, and transportation, the carbon industry is a small industry, but it occupies an important position and plays an important role in the development of the national economy in China. According to China's first five-year plan, 156 large-scale projects were newly built, of which the carbon industry accounted for two projects. For example, the development of the steel industry cannot be separated from carbon materials and products, especially electric furnaces for smelting alloy steel, which must have graphitized electrodes. Electrolytic aluminum production requires the consumption of 400-450kg of carbon anodes for each ton produced. In addition to ordinary civilian industries, carbon fiber composite materials have a wide range of applications in aviation, aerospace, nuclear energy, military and other fields, such as high specific strength, light weight, an
