Abstract
Abstract An extended wear-life composite wear structure particularly suitable for use as a liner in the form of modular panels, generally including a ceramic layer of spaced apart ceramic tiles, each having at least one anchor receiving structure therethrough, overlying a resilient energy absorbing layer separating the ceramic layer from a base layer, and ceramic tile anchors linking each of the ceramic tiles to the base layer via cooperative engagement with the anchor receiving structures of the ceramic tiles. This composite structure permits independent temporary displacement of each of the tiles upon a surface impact, improved retention of the tiles, and greatly enhances the overall structural integrity of the composite as the intermediate layer, layers and or structures are securedly "sandwiched" between the abrasion and impact resistant ceramic layer and the structural base layer.
