The present invention is directed to composites and multi-composites of a prefabricated core of a cellulosic honey comb filled with a rigid polyurethane and layers of fiber saturated thermoset resins. More specifically, the present invention is directed to composites and multi-composites of a cellulosic honey comb filled with rigid polyurethane prefabricated core and a fiber reinforced material, either fibers or woven fibers selected from the group consisting of glass, polyester, carbon and aramid fibers as a mat or cloth saturated with a thermoset resin selected from the group consisting of catalyzed polyester, amine catalyzed epoxy, catalyzed vinyl ester and acid catalyzed furan resins.
