Summary

This work investigates the infiltration of molten aluminum into a network of preheated fibers using an infiltration apparatus which allows continuous measurement of the position of the metal as it infiltrates a perform of Saffil™ fibers. An analytical model is used to treat infiltration as viscous flow through a regular array of cylinders. Taking into account the solidified metal and the fibers, calculated values of permeability agree well with those measured experimentally. The effect of thermal losses to the surrounding environment are also modeled, with results presenting the effect of fiber temperature, fiber volume fraction, and infiltration pressure on total infiltration length. Results from theoretical calculations are compared to experimental data.
