ABSTRACT:
A composite structure comprising a rigid closed-cell foam core element to which is bonded an initially resilient open-cell foam material and a layer of high strength reinforcing material which are compressed against the core element so as to cause a thermosetting resinous material to form a resin matrix extending throughout the open-cell material and reinforcing layer to bond the composite layers together.
