ABSTRACT

Recently a continuous process has been developed for manufacturing wires made of a fiber-reinforced metal matrix composite. In the process a fiber preform is fed continuously into a high-pressure crucible containing molten metal for melt infiltration, and comes out as composite wire. A series of tests show that there exists a range of process speed in which the composite wire is produced smoothly without any leakage of melt. A thermofluid model is developed to understand the most crucial part of the system, the entrance gate section to the crucible. The model prediction agrees well with our test observations of the process.
