Abstract

A method of preparing a fiber glass reinforced resin sheet comprising continuously feeding one or more fiber glass mat(s) 102, 103 to a heating zone 120, introducing resin e.g. in the form of sheets 100, 101 into the zone with the mat(s), applying pressure to the mat(s) and resin e.g. by platens 121, 122 at a temperature sufficient to melt the resin and thoroughly wet the mat(s), cooling the mat(s) in a cooling zone 130 to solidify the resin into a resin-mat sheet while maintaining pressure on the resin and mat(s) during cooling e.g. by platens 131, 132 at least equal to the pressure applied to the resin and mat(s) in the heating zone, and removing from the cooling zone a solid sheet of glass mat reinforced resin. In an alternative procedure, pressure is applied by passing the assembly under tension around pressing rollers. <IMAGE>
