ABSTRACT:
An apparatus and method are provided for forming large filament reinforced composite bodies. In one form a substrate is formed by rotational molding a plastic material in a mold cavity after which the molding is removed from the cavity and placed in a filament winding fixture wherein filamentary material is wound thereon to provide substantial reinforcement for the article and strengthen the outer stratum thereof. In a particular form, the rotational molding contains a rigid tubular member extending therethrough and secure therein during the rotational molding process and is utilized for the purpose of supporting the rotational molding in the filament winding fixture. In another form, an inflatable substrate is constructed with a rod or tubular member extending therethrough which member is utilized to support the inflated member in a filament winding fixture. Plastic and filamentary material are disposed against the inflated outer surface of the inflatable member in a winding operation which forms a hard, filament reinforced shell on its outer surface. In a particular form, a hard plastic material is spray deposited or otherwise formed on the outer surface of the inflated member while it is rotated in a fixture and after a self supporting shell is formed thereof, glass fibers or other filamentary material is wound against the hard shell as it is rotated in a filament winding fixture.
