Abstract

A layered structure has superior properties because it is prepared by spraying two part liquid resin polymers that chemically react very quickly to become solid, to form each layer. A novelty is preparing all layers from a thermoset resin, which is possible because all layers are added by a spraying means. Structures are formed into articles such as boat hulls, truck liners, bathtubs, and automobile parts, using suitable molds. The articles have desirable properties such as durability, and relatively light weights. Moreover, they are produced more rapidly and inexpensively than similar layered articles produced by other methods.
