The flow behavior of an AlSi10Mg alloy melt in Saffil chopped fiber preforms during liquid metal infiltration aided by squeeze pressure or vacuum has been visualized. Experimental results indicate that under the external pressure the flow behavior of the melt in non-wetting chopped fiber preforms is dominated by capillary laws and the geometrical characteristics of the interspaces in the preform in a manner analogous to flow in a capillary tube network. The degree of saturation of the interspaces is dominated by local infiltration pressure, and variation of the saturation degree at a given infiltration depth is determined by fiber distribution uniformity at the microscopic level.
