<p>A continuous method for the production of composite materials from epoxy resin laminates in a heated double-belt press is proposed. The prepregs used are binder-impregnated porous substrate materials, the binder consisting of an epoxy resin, a novolak based on bisphenol and 0.5 to 2.0 % by weight of imidazole. Curing is preferably effected at temperatures above 180 DEG C.</p>
