Abstract
A wall structure for commercial transportation equipment and containers. The wall structure includes outer skins with core material and a thermoplastic laminate reinforcement positioned between the outer skins such that the thermoplastic laminate reinforcement is selectively arranged at portions of the wall structure to provide strength and stiffness. The wall structure is thermoformable to provide integrated features that integrally extend from the structure to accommodate design features and attachment supports.
Claims20
A composite wall structure for a transportation container, the composite wall structure comprising:
- a. a top edge surface, a bottom edge surface, a first side surface and a second side surface;
- b. an inner polymeric skin forming a first wall surface;
- c. an outer polymeric skin forming a second wall surface;
- d. a core material positioned between the inner polymeric skin and the outer polymeric skin;
- e. a thermoplastic laminate reinforcement positioned between the inner polymeric skin and the outer polymeric skin, the thermoplastic laminate reinforcement is located at or near the top edge surface or the bottom edge surface of the composite wall structure, and the thermoplastic laminate reinforcement being a different material than the core material,
- wherein the core material and the thermoplastic laminate reinforcement are thermally fused to the inner polymeric skin and the outer polymeric skin.
A composite wall structure for a transportation container, the composite wall structure comprising:
- a. a top edge surface, a bottom edge surface, a first side surface and a second side surface;
- b. an inner polymeric skin forming the first side surface;
- c. an outer polymeric skin forming the second side surface;
- d. a foam core material positioned between the inner polymeric skin and the outer polymeric skin;
- e. a first thermoplastic laminate reinforcement positioned between the inner polymeric skin and the outer polymeric skin, the first thermoplastic laminate reinforcement extends along the entire top edge surface;
- f. a second thermoplastic laminate reinforcement positioned between the inner polymeric skin and the outer polymeric skin, the second thermoplastic laminate reinforcement extends along the entire bottom edge surface,
- wherein the foam core material, the first thermoplastic laminate reinforcement, and the second thermoplastic laminate reinforcement are thermally fused to the inner polymeric skin and the outer polymeric skin, and
- wherein the inner polymeric skin and the outer polymeric skin are continuous and form the respective entire height and width of the first side surface and the second side surface.
A composite wall structure for a transportation container, the composite wall structure comprising:
- a. a composite wall portion that forms a sidewall of the transportation container, the composite wall portion comprising:
- i. a top edge surface, a bottom edge surface, a first side surface and a second side surface;
- ii. an inner polymeric skin forming the first side surface;
- iii. an outer polymeric skin forming the second side surface;
- iv. a core material positioned between the inner polymeric skin and the outer polymeric skin;
- and
- b. an aerodynamic extension formed by a portion of the outer polymeric skin extending downward from the composite wall portion and below the inner polymeric skin and a bottom side of the transportation container.
