ABSTRACT:
A method for high speed continuous production of reinforced plastic sheets and reinforced plastic sheet laminate structures which may have widths ranging from relatively narrow to very wide. One or more layers of resin impregnated, fiber-containing, reinforced plastic composite material is brought into contact with surfaces of one or more endwise abutted relatively flat panels. The panel or panels are then passed between a pair of continuously rotating belts. A pressurized air body is formed in a plenum chamber which faces the interiorly presented surface of at least one of the belts and which air body is between the housing forming the plenum chamber and the interior surface of the belt. Preferably, a similar housing creates a pressurized air body between such similar housing and the other of the belts. In this way, the pressurized body of air forces the belts into intimate contact with the layers forming the reinforced plastic laminate structure. The body of air is generally at a uniform pressure in the area between the belts and associated housings. In like manner, a single sheet of resin impregnated fiber-containing material may be passed between the belts where the resin is cured during the application of pressure to form a rigid single ply sheet structure. The method may use an augmented cure so that a cure of the resin is initiated in a precuring mechanism, and the reaction proceeds to a final cure while the layer or layers pass between the belts. The belts may be heated so as to facilitate the curing of the resin matrix impregnated in the layer or layers containing the fiber-reinforcing material.
