ABSTRACT:
The invention is a process for building a lamination of a fiberglass reinforced polyester resin on a rotating continuous belt forming a spirally rotating mandrel consisting of pouring resin on the top of the mandrel from a substantially horizontal surface, depositing chopped strands of fiberglass onto the surface of the resin and impressing the chopped fiberglass into the resin with parallel strands of a suitable material. The specific method of pouring the resin onto the mandrel surface and the application of chopped fiberglass and parallel strands are also part of the invention.
