Abstract
A panel for use in a foundation or above-grade may be made with studs for strength, and for attachment to an interior wall. The composite panel has two outer facing sheets, and a core. Studs are provided on one of the outer facing sheets. The manufacturing process involves forming the panel on a mold by laying down a gel coat (optional), a lower facing sheet (used instead of, or with, the gel coat), the core piece(s), and the top facing layer. This can be done by a lamination process, or preferably is done by laying down fibrous material for the facing sheet(s) and vacuum-infusing it with resin, and curing the panel. The core pieces may either be pre-made, or (if infusion is used) may themselves be made in this process, by infusing them with the resin as well. The studs are preferably of galvanized steel and are secured by means of an adhesive.
