A panel includes a fiberglass substrate encapsulating an aesthetic material. The fiberglass substrate and the aesthetic material are both impregnated with resin to form the solid-core of the panel. The solid-core panel can be manufactured by arranging multiple layers of a fiberglass material between multiple plates, interleaving aesthetic material between at least two of the layers of fiberglass material, applying resin to the multiple layers of fiberglass material and the aesthetic material, and then allowing the combination of the resin, multiple layers of fiberglass material, and the aesthetic material to cure between the plates, forming a solid-core panel encapsulating the aesthetic material.
