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

Let's talk about the basic characteristics of graphite

I. Special seismic resistance: Graphite's expansion gear is different, so the macro expansion coefficient is not large. In the case of sudden changes in temperature, graphite volume has not changed much; coupled with its good thermal conductivity, graphite resistance is excellent.Second, lubrication: The graphite layer is Van Der Waal Forces, which combines weak combination to make it lubricating. The lubrication of graphite depends on the size of the graphite scales. The larger the scales, the smaller the friction coefficient, the better the lubricity.Third, good chemical stability and resistance to erosion: Graphite has good chemical stability at room temperature, not subject to any strong acid, strong alkali and organic solvents; the carbon atom in the graphite layer is firm Combining, the surface of graphite phosphorus can be very low, not moisturizing by melting furnaces, and strong resistance to erosion. However, graphite is prone to oxidation in the air, and anti -oxidation mea

What are the characteristics of the thermal stability of the film -shaped graphite

Sheet -shaped graphite is a natural ore, with a thin piece or scale, and the aggregate is in the form of soil. It is a hidden crystal. Film graphite has many high -quality physical and chemical characteristics, including good thermal stability. Compared with other products, the thermal stability of film -like graphite has great advantages.Film graphite is one of the most high -temperature -resistant materials at present. Generally, the strength of the material is gradually decreased at high temperature. However, when heating to 2,000 degrees Celsius, the strength of the sheet -shaped graphite is twice the temperature at room temperature.Sheet -shaped graphite has excellent heat shock resistance. When the temperature suddenly changes, the thermal expansion coefficient is small, so it has good thermal stability. When the temperature changes rapidly, cracks will not occur.Sheet -shaped graphite is a material with excellent thermal shock. For graphite electrodes used in electric furnace s
