A method for manufacturing a composite part by laying up courses of composite tape using an automated tape layup (ATL) machine onto a conductive flexible facesheet laid flat on a flat surface, and then transferring the facesheet with the composite material thereon to a curved tooling surface for attachment of substructures and curing into the composite part. The method may also include applying insulation below the facesheet and above the composite material, then heating the conductive facesheet to cure the composite tape and fuse the composite tape to the substructures without heating the tooling surface or any other items used to compress and cure the composite material into the composite part. Heating of the facesheet may be performed using joule heat provided by a single turn transformer inducing current to a plurality of conductive wires attached at opposing ends to the facesheet.
