Methods include providing a plurality fabric material layers, applying a plastisol layer between each fabric material layer forming plurality fabric material layers thereby creating a belt carcass, pressing the fabric material layers together with the plastisol layer(s) at a pressure of at least 5 psi to produce a preformed fabric carcass while heating the preformed fabric carcass while heating the preformed fabric carcass to a temperature which is within the range of about 360° F. to about 450° F. for a period of at least 6 minutes, disposing a thermoplastic elastomer polyvinyl chloride alloy composition onto the upper and lower surfaces of the fabric carcass, pressing the thermoplastic elastomer polyvinyl chloride alloy composition onto the upper and lower surfaces of the fabric carcass, and splicing opposing distal ends of the belt in a stepped splice configuration. The layers may be devoid of covering strips of lattice fabric disposed adjacent an abutment of any proximally positioned fabric layer.

The present invention provides a fiber-reinforced resin intermediate material, including not only a thermoplastic resin but also a thermosetting resin, in which defects such as voids are difficult to be generated and which is excellent in shaping ability; and a method for manufacturing the same. The fiber-reinforced resin intermediate material according to the present invention is a fiber-reinforced resin intermediate material formed by attaching a resin to an outer surface part of a reinforcing fiber substrate formed of reinforcing fibers subjected to opening and heating the resin to a temperature equal to or higher than the melting point of the resin to impregnate the reinforcing fiber substrate with the resin, wherein the reinforcing fiber substrate has void space that is opened on an outer surface thereof and the resin is in a semi-impregnated state.

A method of cosmetically altering a fiberglass piece comprising having a graphical element disposed on a layer of textile fabric. An outer layer of a curable gel-coat is applied to a mold for the cosmetically altered fiberglass piece. At least one intermediate layer of textile is then applied over the outer layer, the textile comprising a graphical element disposed adjacent to the outer layer. An inner layer is then applied to the intermediate layer, the inner layer providing structural support to the fiberglass piece. A bonding agent is then applied to wet out the outer layer, the intermediate layer, and the inner layer, thereby resulting in an assembly of a wet out three-layer combination, the curing of which results in the cosmetically altered fiberglass piece.
