PROCESS FOR MAKING COMPOSITE MATERIALS FROM REFRACTORY FIBERS AND METAL

摘要

A process for the manufacture of a composite material comprises providing in a mould an admixture of reinforcing refractory fibers and a molten metal, applying to the admixture an encapsulating pressure program until a desired densification is achieved and at least during initial application of the encapsulating pressure program arranging adjacent each path of potential leakage from the mould a heat sink having a heat capacity sufficient to solidify molten metal contacting the heat sink and thereby seal the said leakage path.
