Abstract
A laminated structural panel which is especially well suited for the construction of a bulkhead used to partition a trailer or other cargo container. The center of the panel is formed by a polyurethane foam core panel sandwiched between a pair of flexible plastic reinforcing sheets adhesively bonded to opposite sides of the core panel. Additional layers of foam are adhesively bonded to the reinforcing sheets, and the outer foam layers are covered by puncture and abrasion resistant skins which are adhesively bonded to the foam. The reinforcing sheets provide the structural foam with tensile strength and with both beam and column strength because of their ability to resist being stretched. The outer foam layers provide impact resistance and enhanced strength due to the effect of the added laminations.
