Characterization of liquid metal infiltration of a chopped fiber preform aided by external pressure. 2: Modeling of liquid metal infiltration process
Based on the visualized flow behavior of Al10SiMg alloy melt in Saffil chopped fiber preforms, unidirectional infiltration of a chopped fiber preform aided by squeeze pressure has been analyzed. The relationships between melt flow and process parameters have been statistically established by the hydrodynamic analysis. The stress distribution, the variation of saturation degree and the formation of cavities due to air entrapment in the preform during infiltration have been discussed together with the analysis results.
