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.

Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
