ABSTRACT:
A method is disclosed for the formation of three dimensional composite articles by use of an aqueous slurry containing thermoplastic powder. The slurry is retained by a rotating wheel that is capable of dewatering and drying the slurry sufficiently within molds carried by the wheel so as to dimensionally stabilize the three dimensional composite prior to its release from the wheel. The thermoplastic powder used in the process of the present invention has a specific gravity greater than 1, and therefore mixes homogeneously with the other components of the aqueous slurry so as to yield a composite having similar mechanical properties across its entire cross section.
