Abstract

Obtaining a strong bonding on the carbon fiber and aluminium matrix interface, require a favorable wetting conditions and limitations reactivity between the aluminium matrix and carbon fibres. In the processes of infiltration, one of the factors conducive to such a connection is the chemical composition of the alloy matrix. The composition of the alloy also decides on technological properties such as castability and shrinkage. The paper presents the results of comparative fluidity tests of AlSi9Cu(Fe) and AlSi9Mn alloy with addition of magnesium and strontium. It was compared the metal flow path in the beam with a width of 20 mm and different thicknesses in the graphite mould. In case of modified alloy AlSi9Cu(Fe) + 1% Mg +0.03%Sr was observed a slight decrease of fluidity. While in the case of alloy AlSi9Mn+ 1% Mg +0.03%Sr length of filled increased comparing to similar beams on base alloy.
