ABSTRACT:
A method for forming a monolithic composite slat for a lightweight pallet. The slat is formed by adhering the crests of a corrugation to one side of a reinforcement sheet, placing another side of the reinforcement sheet in spaced, parallel relation with the corrugation and the first side such that the corrugation is situated between the first and second sides, inserting a flexible fiber in each trough of the corrugation and using each fiber to urge the trough toward the second side, inserting foam-forming material between the first and second sides, and allowing the material to cure, thereby forming a solid, foam-filled slat. The method is advantageous over that of the prior art, as it ensures that the corrugation remains in place during inserting of the foam-forming material.
