Abstract:
1. A composite lap joint for joining floor boards in a vehicular trailer comprising: a first composite floor board disposed adjacent to a second composite floor board, the first and second composite floor hoards each having a top side and a bottom side, wherein each of the first and second composite floor boards comprises: a composite lip formed by the composite layer at one of the opposing lateral side: edges of the wood layer of the first composite floor board, wherein the composite lip is a lateral extension of the composite layer of the first composite floor board; and a bottom side recess at one of the opposing lateral side edges of the wood layer of the second composite floor board, for mating with the composite lip of the first composite floor board, wherein the composite lip is disposed under the bottom side recess of the second. composite floor board to form the composite lap joint and a seam, whereby the composite lap joint provides moisture seal mg ability at the seam and provides savings in volume of wood of the wood layers of each of the first and second composite floor boards as compared to a shiplap joint joining composite floor boards; wherein a part of the composite layer away from the composite lip of the first composite floor board is bonded to the wood layer with a first adhesive, and a part of the composite layer at the opposing lateral side edge close to the composite lip of the first composite floor board is bonded with a second adhesive or sealant capable of stretching under load, thus allowing the composite lip to flex and reduce load transfer between the first and second composite floor boards.
