A method of forming a layered composite material of the type formed under heat and low pressure and to one outer surface of which a protective thermosetting polymer is bonded.

Method for making a composite structure

An apparatus for forming continuous lengths of composite material comprised of a core of resilient and open-cell foam material impregnated with an uncured thermosetting resin and which core element is overlaid with at least one outer layer of a reinforcing material.

Foam impregnating apparatus

A composite structure comprising a layer of initially resilient foam material having open and connected cells one portion of which is impregnated with a first polymerizable resin system and another portion of which is impregnated with a second polymerizable resin system and which resin systems are concurrently polymerized while maintaining the resilient foam layer under compression whereby each polymerized resin is disposed as a continuous and rigid resin phase throughout respectively adjacent portions of said foam material.
