The mechanical properties of CFRP depends mainly on the matrix, the mechanical properties of common epoxy resin , the surface properties of carbon fiber, and the nature of the fiber and the matrix bonding interface, and the performance of the matrix and fiber surface properties directly related to the interface bonding and adhesive performance, the following described from two aspects: 1、Matrix: CFRP commonly used epoxy resin as matrix, its good adhesion, excellent mechanical properties, but the general type of epoxy resin after curing, brittle hard, shock resistance is poor, poor heat resistance. At present, the toughening method is relatively mature will cure before can compatible rubber and epoxy resin dissolved in resin, curing, rubber to precipitate, a two phase structure.…

1, Graphite can be used as a refractory material: graphite and its products have properties of high - strength, high temperature resistance, mainly used to produce graphite crucible in the metallurgical industry, in steelmaking in graphite is usually used for the protection of steel ingot agent, metallurgical furnace lining. 2, Graphite can be used as the conductive material: used for manufacturing electrode, carbon brush, carbon rod, carbon nanotubes, mercury is the cathode in electrical industry, graphite gaskets, telephone parts, TV picture tube coating. 3, Graphite can be used as a wear-resistant material: Graphite in the mechanical industry often as a lubricant. Lubricating oil is often not used in high speed, high temperature and high pressure, while the graphite wear resistant…

Crucible is mainly divided into three types of graphite crucible, clay crucible and metal crucible. In order to adapt to the development of social economy, people invented the innovation, expand the scope of its use, such as graphite crucible, silicon carbide crucible, electric furnace crucible, crucible, intermediate frequency furnace isostatic pressing graphite crucible, and so on. GW group, professional build graphite products for 30 years, this article is about the advantages of molten copper graphite crucible: (1) high heat conductivity, by using the high thermal conductivity graphite and other raw materials, shorten the melting time. (2) heat shock, heat shock performance is strong, for thermal shock, not easy to burst; (3) the high heat resistance, high refractoriness, resistant to 1200…
