Guangdong aerospace materials Silica Price

I. Overview of aerospace materials Silica: Silica aerospace materials used to carry the spacecraft propulsion system orbit the heart of the engine, oxidizer tank, fuel tank and other key equipment, carbon fiber composite material density is one-quarter steel , use it to make structural member Compared with aluminum, it can weight 30 to 40%. Propulsion module load-bearing structure in the world is the size of the maximum use of manned spacecraft, opening the largest carbon fiber composite main load-bearing structure, a diameter of 2.5 meters. Popular terms, the role of this structure is equivalent to a fixed spacecraft propulsion module in the big box, a box to precisely fix hundreds of pieces of equipment. Second, our product specification sheet: Aerospace Material Specification with silica powder 800 mesh 400 mesh 600 mesh mesh 1250 1000 1500 4000 2000 mesh mesh mesh mesh 8000 6000 10,000 head three head, aerospace material superiority microsilica: Aviation aerospace materials silica powder is ether type epoxy resin, while most of bisphenol A type epoxy resin-based, bisphenol F-type epoxy resin (DGEBF) and bisphenol S-type epoxy resin. Followed by glycidyl amine epoxy resin and glycidyl epoxy resin. Others include phenolic epoxy resins; resorcinol-type epoxy resins, resorcinol - formaldehyde epoxy resin, epoxy ethane tetraphenol three hydroxyl ben methane type epoxy resins, full flexibility aliphatic polyol ether type epoxy resin, epoxy acrylate resin and weatherability cycloaliphatic epoxy resins, which can be used alone or in combination with Universal E-type resin blends, made for high-performance composite material (ACM). Fourth, aerospace materials silica powder variety, performance and features: aerospace materials Silica is an excellent reaction curable resin. In the fiber-reinforced composite materials, the epoxy resin flourish. It is the high-performance fiber: PAN-based carbon fiber, aramid fiber, polyethylene fiber, basalt fiber, S or E glass fiber composite, it will become an irreplaceable matrix materials and structural materials, widely used in power electronics, aerospace, sports equipment, construction reinforcement, pressure pipe male, chemical corrosion and other six areas. This article focuses on the present situation of advanced aerospace resin matrix composite materials and technical weakness of China's problems.
