Study on Microstructure of Continuous Cf/Al Composite Material Prepared by Hot Pressing Diffusion Method
Abstract:
Two-dimensional carbon fiber fabric T300 used as reinforcement, Cf/Al composite material was prepared by hot pressing diffusion. Effect of parameters on microstructure of Cf/Al composite material was studied. We found that for aluminum foil used as matrix, hot pressing temperature is 650°C, hot pressing time is 20min, pressure is 30MPa. As a case, interfacial reaction product Al4C3 accounts for 3.6%, and composite material density is 2.44g/cm3. For aluminum powder used as matrix, hot pressing temperature is 620°C, hot pressing time is 35min, pressure is 10MPa. As a case, Al4C3 accounts for 2.8%, and composite material density is 2.58g/cm3. The molding of aluminum powder is much easier than that of aluminum foil. The latter requires higher hot pressing temperature. Interfacial reaction product Al4C3 increases as increasing of hot pressing temperature and pressure.
