Custom formed panels for transport structures and methods for assembling same
Techniques for providing custom formed panels for transport structures including vehicles and aircraft are disclosed. In one aspect of the disclosure, a panel for a transport structure includes a first face sheet, a second face sheet arranged opposite the first face sheet, the second face sheet comprising a different geometrical profile than the first face sheet to define a space between the first and second face sheets having a variable thickness, a core configured to occupy the space. In another aspect, a node can be additively manufactured to form the custom panels by engaging opposing face sheets. The node has an inlet port for providing a foam-like substance into the space between the face sheets to thereafter solidify into a core.
1. A node, comprising;
a base comprising a length of material having a first end and a second end;
a first interface proximate to the first end, the first interface engaging a face sheet edge of a first face sheet while being separated from the face sheet edge of the first face sheet by a first set of isolating structures abutting at least two surfaces of the first face sheet edge;
a second interface proximate to the second end, the second interface engaging a face sheet edge of a second face sheet while being separated from the face sheet edge of the second face sheet by a second set of isolating structures abutting at least two surfaces of the second face sheet edge, such that the first and second face sheets oppose one another; and
a foam inlet port arranged on the base, the foam inlet port configured to enable a flow of a substance into an area defined by at least the first and second face sheets.
2. The node of claim 1 , wherein the first face sheet and the second face sheet occupy, at least in part, planes parallel to one another.
3. The node of claim 1 , wherein the first and second interfaces comprise single-shear interfaces.
4. The node of claim 1 , wherein the first and second interfaces comprise double-shear interfaces.
5. The node of claim 1 , wherein the first set of isolating structures includes a washer.
6. The node of claim 5 , wherein the washer is a nylon washer.
7. The node of claim 1 , wherein the first set of isolating structures comprises an electrically-insulating material.
