1. A composite wall panel of a body having a floor, a roof spaced from and disposed opposite the floor, a pair of opposed sidewalls spaced from each other and extending between the floor and the roof structure, and a front wall and a rear wall opposing each other and extending between the floor and the roof, wherein the body is configured to be supported and transported by at least one pair of wheels, the composite wall panel comprising:
a first polymer resin layer having a plurality of unidirectional fibers embedded therein, the plurality of unidirectional fibers being substantially parallel to a first fiber axis; a second polymer resin layer having a plurality of unidirectional fibers embedded therein, the plurality of unidirectional fibers of the second polymer resin layer being substantially parallel to a second fiber axis, the second polymer resin layer, the second polymer resin layer being bonded to the first polymer resin layer so that the second fiber axis is substantially perpendicular to the first fiber axis; and a third polymer resin layer having a plurality of unidirectional fibers embedded therein, the third polymer resin layer being bonded to the second polymer resin layer opposite the first polymer resin layer so that the plurality of unidirectional fibers of the third polymer layer is substantially parallel to the first fiber axis, the first, second, and third polymer resin layers forming a unitary polymer resin layer, wherein the composite wall panel forms a portion of at least one of the roof, the opposed sidewalls, the front wall, and the rear wall, and wherein a glass to resin ratio of the unidirectional fibers within the unitary polymer resin layer that are parallel to one of the first fiber axis and the second fiber axis is greater than a glass to resin ratio of the unidirectional fibers within the unitary polymer resin layer that are parallel to the other of the first fiber axis and the second fiber axis. |
