Patent ID: 7276868

Claim:
Is allowable over the prior art for a method of making a musical instrument soundboard from carbon-fiber laminate material comprising the steps of: a) providing at least one layer of carbon fiber material with epoxy resin, for forming a face layer; b) laying the epoxy wetted material on a smooth surface; c) placing a core material over the wetted carbon fiber face layer ( 1 ); d) placing shaped additional layers of material on the core material, to provide desired stiffness by building up a graduated thickness of the core in selected positions; e) wetting carbon fiber material forming a back layer; f) placing the back layer of epoxy wetted carbon fiber over the core material and additional layers; g) applying a layer of peel-ply and/or release-ply-over the back layer; h) placing a “breather” layer over the back layer; i) encasing all of the layers in an airtight plastic bag; j) evacuating the air from the bag; k) allowing the epoxy to cure; I) removing the bag; and m) separating the smooth surface and the peel-ply, release-ply and breather layers from the finished laminated sound board.
