Abstract
A composite structure is disclosed which is especially useful as a sidewall for trailers. The structure, however, because it is very strong can be used for end walls, roofs or floors and even prefabricated housing. The composite structure provides all the advantages of wood framing and aluminum framing and has good raking characteristics. A method of producing the structure is also disclosed which can be used in a production line assembly operation.

A composite structure for mobile carriages comprising:
- an interior paneling having a finished planar first surface, an opposite thereto planar second surface and a thickness therebetween;
- wood framing having a planar first surface, an opposite thereto planar second surface and a thickness and a traverse surface therebetween, said first surface of said wood framing being bonded to a small portion of said second surface of said interior paneling thereby leaving a large remaining surface area of said second surface of said interior paneling spaced away from said wood framing;
