1. A composite wall panel of a vehicle having a floor structure that is supported by at least one pair of wheels, a roof structure spaced from and disposed opposite the floor structure, a pair of opposed sidewalls spaced from each other and extending between the floor structure and the roof structure, and a front wall and a rear wall opposing each other and extending between the floor structure and the roof structure, the composite wall 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 of the composite wall panel; 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 of the composite wall panel, 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 of the composite wall panel, the first, second and third polymer resin layers forming a unitary polymer resin layer, wherein the composite wall panel forms a curved portion of the front wall and is disposed so that the first fiber axis is substantially parallel to the floor structure, and rigidity of the composite wall panel is greater along the first fiber axis than the second fiber axis. |
