Abstract
Official abstract text for this publication.
A multi-sheet component for a utility vehicle that includes at least one gap between at least two of the sheets, thereby providing a component that enhances worker safety by increasing component stiffness and reducing component thickness. The component is manufactured through multi-sheet thermoforming and uses a conical frustum corrugation to increase stiffness.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for manufacturing a multi-sheet component consisting of a first sheet and a second sheet for a utility vehicle, comprising: thermoforming the first sheet; inserting a core material between the first sheet and the second sheet; and manufacturing the second sheet onto the first sheet and the core material using lamination and/or 3D printing; wherein the multi-sheet component is a hinged door; wherein the core material is removed after manufacturing the second sheet; wherein the first sheet and the second sheet are separated by at least one gap; wherein a corrugation on the first sheet extends into the component to meet the second sheet, thereby creating a mounting location on the first sheet to mount conductive hardware through; wherein the mounting location is recessed into the first sheet, thereby shielding the conductive hardware from contacting a conductor greater than the width of the corrugation on the first sheet; and wherein the first sheet and/or the second sheet is made from dielectric materials including reinforced thermosets, unreinforced thermosets, reinforced thermoplastics, and/or unreinforced thermoplastics. 2. The method of claim 1 , wherein the corrugation includes a conical frustum corrugation, and further including the step of forming the conical frustum corrugation in the first sheet when forming the first sheet; and wherein the frusta have base diameters of between about 2 and about 4 inches. 3. The method of claim 1 , further comprising filling the gap with pressurized or non-pressurized air after manufacturing the second sheet. 4. The method of claim 1 , wherein the corrugation on the first sheet includes a frustum corrugation, and wherein the first sheet is thermoformed to include the frustum corrugation.
