ABSTRACT:
An apparatus and method for making composite articles of a plurality of materials including a matrix having predeterminately disposed therein a plurality of filament-like formations of one or more secondary materials which serve to substantially enhance and predetermine the strength of the matrix.
In one form the matrix is composed of metal, while the reinforcing material is composed of filaments or whiskers defining crystals of metal or ceramic materials such as boron nitride, silicon carbide, titanium nitride, etc. One form of the apparatus is operative to feed said filaments or whiskers from a supply thereof while another form is operative to extrude filaments of said materials to shape and directly feed said extruded filaments into a molten metal matrix.
In another form of the invention, a hot molten glass is formed into a plurality of filaments which are fed directly, as they are formed, into a matrix composed of a thermosetting or thermoplastic material and they serve to substantially reinforce said matrix material.
