    Abstract: A composite panel manufacturing process with interlocking connections. The method includes laying out the first sheet of pre-preg epoxy carbon fiber, upon a polished and released aluminum tool. A second sheet of epoxy fiberglass is laid out over the top side of the first sheet. Rigid structural foam is laid on top of the second sheet of epoxy fiberglass. A third sheet of pre-preg epoxy fiberglass is laid on top of the rigid structural foam. A fourth sheet of pre-preg epoxy carbon is laid on top of the third sheet of pre-preg epoxy fiberglass with heavy resin/top side out to form a plurality of panels. The plurality of panels are cured to form a multilayer panel. Core material is removed along one edge of a first multilayer panel to make a U-shaped channel having a base and parallel flanges. A grooved slot is cut along one edge of the next multilayer panel. The panels are joined at the corner using an adhesive.
