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.
L'invention concerne un matériau composite de matrice d'aluminium consistant en une préforme de fibres poreuses qui est incorporée dans un alliage d'aluminium et qui a une force et un comportement à l'usure supérieurs à ceux de la matrice d'aluminium. La préforme de fibres consiste en un élément de fibres profilé qui comprend une structure métallique et/ou intermétallique et dans laquelle est infiltrée une coulée de silico-aluminium contenant jusqu'à 5-14 % en poids de Si. De plus, l'invention concerne un processus de production d'un matériau composite de matrice d'aluminium qui consiste en une préforme de fibres poreuses infiltrée par un alliage d'aluminium.
