Composite panel edge treatments and joints and cargo body having same

A cargo body comprising:

• a floor;
• a roof;
• and
• a plurality of sidewalls extending between the floor and the roof to define a cargo receiving volume in cooperation with the floor and the roof, each one of the plurality of sidewalls constructed of a plurality of panels including adjacent pairs of panels secured together at respective joints,
• wherein each of the plurality of panels is an assembled panel having a core, an interior skin secured to a first side of the core facing the cargo receiving volume, and an exterior skin secured to a second side of the core opposite the first side,
• wherein each of the joints is formed as a lap joint in which an edge portion of a first one of the adjacent pair of panels overlaps a portion of a second one of the adjacent pair of panels, and an edge portion of the second one of the adjacent pair of panels overlaps a portion of the first one of the adjacent pair of panels,
• wherein the first one of the adjacent pair of panels has a reduced-thickness core portion throughout the edge portion in which a core thickness measured between the interior and exterior skins is less than a maximum core thickness of the first one of the adjacent pair of panels,
• wherein the second one of the adjacent pair of panels has a reduced-thickness core portion throughout the edge portion in which a core thickness measured between the interior and exterior skins is less than a maximum core thickness of the second one of the adjacent pair of panels, and
• wherein the core of each of the plurality of panels is a profiled sheet of anticlastic form such that the maximum core thickness of the first one of the adjacent pair of panels is defined by interspersed peaks and valleys thereof, and the maximum core thickness of the second one of the adjacent pair of panels is defined by interspersed peaks and valleys thereof.
