ABSTRACT:
A laminated article comprising a plurality of abrasive resistant ceramic tiles secured to an elastomeric polyurethane cushioning support by means of a multitude of short thin fibers having major portions thereof embedded within an epoxy resin bonded to the tiles is fabricated by applying a thin layer of the resin in an uncured liquid phase to the tiles, applying a coating of the fibers to the liquid resin such that minor portions of the fibers in contact with the resin are wet thereby and the remaining major portions of the fibers extend from the resin layer, curing the resin to secure the fibers therein and to bond the resin to the tiles, applying a layer of a thermosetting polyurethane in an unpolymerized liquid phase to the fiber impregnated resin layer, and thereafter curing the polyurethane layer.
