ABSTRACT:
A composite is disclosed which comprises one or more interwoven matrix compositions, each containing a refractory hard metal; and from 0 to 80 wt. % of at least one previously formed refractory hard metal. In one embodiment, the composite may comprise two interwoven matrix compositions which were formed by mixing the reactants together prior to forming the interwoven matrix compositions whereby the exothermic heat of react may be controlled by selection of proper ratios of reactants. In another embodiments, previously formed refractory hard metals or previously formed interwoven matrix compositions may be used in the formation of the composite to control the exothermic heat liberated during formation of the interwoven matrix composition or for other purposes such as densification of the composite.
