Abstract: A pressure casting apparatus with an velocity-adjustable system has been developped to make C/AL composite.Investigations are focussed on its infil- tration process.The results show that with the increase of fiber volume fraction,the unhomogeneous infiltration of liquid metal changes into homog- eneous one.The wetting between metal and fiber is a prerequisite for good infiltration.Metal infiltration velocity is proportional to the square root of the pressure spced.And only at the considerable fiber volume fraction,do the infiltration coeffilients agree to the calculations of the bundle-aggregates kinetics.By a proper control of process parameters,the sound composite can be produced.
