ALUMINIUM MATRIX COMPOSITE MATERIAL AND PROCESS OF PRODUCING SAME

摘要

The invention relates to an aluminium matrix composite material consisting of a porous fibre preform which is embedded in an aluminium alloy and which has a higher strength and an improved wear behaviour as compared to the aluminium matrix, wherein the fibre preform consists of a shaped fibre member which comprises a metallic and/or intermetallic structure and into which there is infiltrated a silicon-containing aluminium alloy melt, with the Si-content of the melt amounting to 5 - 14 % by weight. Furthermore, the invention relates to a process of producing an aluminium matrix composite material which consists of a porous fibre preform infiltrated with an aluminium alloy.
