Abstract

Abstract: On the basis of fluid kinetics,a model for infiltration kinetics of liquid metals into fibre pre- fabricated composite has been proposed.The infiltration processing,together with the measurements of infiltrating velocity and permeability,for the C fibre-reinforced Al matrix composites have been studied.The model proposed seems to be in good agreement with the ex- perimental results.Two different infiltration modes,uniform and non-uniform,were found and a new technique was suggested.Thus,the quality composites of C fibre-reinforced Al may be made under low pressure regardless of non-wettability of liquid metal to the fibres.

Key words: liquid metal, infiltration, C/Al composite
