A composite sandwich structure is provided. The composite includes a first thermoplastic layer, such as a thermoplastic polyolefin, having an inner surface and an outer surface, wherein the inner surface of the first thermoplastic layer does not include a UV stabilizer. A second thermoplastic layer, such as a thermoplastic polyolefin, is spaced and opposed from the first thermoplastic layer, and includes an inner surface and an outer surface, wherein the inner surface of the second thermoplastic layer does not include a UV stabilizer. First and second UV-curable tie layers are disposed on the inner surfaces of the first and second thermoplastic layers. First and second UV-curable adhesive layers are disposed on the first and second tie layers. First and second reinforcement layers, such as fiberglass, are disposed on the first and second adhesive layers. A foam layer, such as polyurethane foam, is disposed between the first and second tie layers.
