In recent years, with the vacuum heat treatment furnace level improving, the vacuum heat treatment won the favorite of some professional people because it has a series of advantages such as degassing, degreasing, anaerobic and automation and so on , but the vacuum heat treatment furnace has a high standard to electric heating element, the deformation, fracture and volatilization of high temperature electric heating element are the important factors of restricting the development of vacuum furnace. In order to solve this problem, we look to the "black gold" graphite. Graphite has the spotless advantages compared with other metal material ,so the graphite, as the heating element, almost can be used in different types of vacuum heat treatment furnace. The advantages…
Carbon fiber composite material used in automobile and aviation industry carbon fiber is the main use of resin, metal, ceramics and other matrix composite, made of structural materials. Carbon fiber reinforced epoxy resin composite material, its specific strength, ratio of the composite index, in the existing structure of the material is the highest. In the density, stiffness, weight, fatigue characteristics, such as the strict requirements of the field, in the requirements of high temperature, high chemical stability, carbon fiber composite materials are quite advantage. Carbon fiber is in the early 50's should be rocket, aerospace and aviation and other cutting-edge science and technology needs, and now also widely used in sports equipment, textile, chemical machinery and medical fields. With the…
Carbon carbon composite material has excellent properties such as high strength, light weight, fatigue resistance and so on. It is widely used in sports equipment, aerospace and other fields. Carbon fiber has excellent properties such as high strength, light weight, fatigue resistance and so on. It is widely used in sports equipment, aerospace and other fields. carbon fiber filament diameter of T800 is smaller than T300 and T700, the difference between the fiber surface properties is large. T800 surface crystalline structure is more complete, resulting in high surface inertia, The existing conventional resin matrix is not suitable for the forming process of T800 carbon fiber. The resin matrix has a great influence on the interfacial properties of T800 carbon fiber…
