METHODS FOR MANUFACTURING COMPOSITE SURFACE ELEMENTS

摘要

A method of manufacturing a stone-faced composite surface element in which a resin-impregnated fibrous matting (5) is applied to each of the two opposite faces of a stone slab (1) while the resin is in an uncured state. A backing layer (6) is applied to each of the exposed surfaces (3, 4) of the fibrous matting (5). The resin is cured to bond each backing layer (6) to the stone surface through the intermediary of the fibrous matting (5). The stone slab is sawn in two along a cutting plane (9) substantially parallel to, and midway between, the two opposed surfaces (3, 4) of the stone slab (1) to leave a thin lamina of stone attached to each backing layer. The backing layers (6) may be constructed in situ by applying to each exposed surfaces (3, 4) of the fibrous matting (5), after they have been attached to the stone slab (1), a layer of a light weight multicellular material (7), and then applying to the outer surface of the multicellular layer an outer skin of material (8).
