Laminated woven fiber reinforced aluminum matrix composites were prepared by hot pressing diffusion method.Effects of hot pressing temperature

hot pressing pressure and hot pressing time on formation and relative density of the composites were analyzed.Forming parameters for preparing laminated woven fiber reinforced aluminum matrix the composition were optimized.Microstructure and interfacial reaction of the composites were analyzed based on the optimized parameters.The results show that hot pressing temperature is mainly responsible for relative density of the composite.The optimized parameters of laminated woven fiber reinforced aluminum matrix composite by hot pressing diffusion are presented as follows:temperature of 640℃

time of 50 min and the pressing pressure of 15 MPa.Based on the optimized parameters

the relative density of the composites reaches 98.5%

and the approximate content of Al4C3 is 3.6%.Compound of carbon fiber and aluminum matrix exhibits desirable.The interface between aluminum matrix and carbon fiber is rough with generation of a little rod-like Al4C3 phase.
