ABSTRACT:
Foamed structures such as those formed of rigid polyurethane can be easily reinforced by a plurality of layers of reinforcement material spaced relatively uniformly throughout their thickness by coating or covering the layers of reinforcement material with absorbent material such as paper, stacking the layers at the bottom of a mold, adding the liquid resin, and curing the resin after it has had sufficient time to wet the absorbent layers. As the resin on the absorbent layers foams, the layers of reinforcement will be simultaneously lifted and spaced from each other to provide uniform reinforcement without the need for special molds or the labor usually required to position spaced layers of reinforcement.
