Abstract
A system and method of a structural panel includes a first outer sheet and a second outer sheet, the first outer sheet and second outer sheet including a polygon shape; a core arrangement sandwiched between the first outer sheet and the second outer sheet, the core arrangement comprising two or more discrete members arranged adjacent each other, the discrete members shaped or structured to reduce crack initiation and propagation within the core arrangement.
Claims33
A structural panel comprising;
- a first outer sheet and a second outer sheet, the first outer sheet and second outer sheet comprise a polygon shape.
- a core arrangement sandwiched between the first outer sheet and the second outer sheet,
- the core arrangement comprising two or more discrete members arranged adjacent each other, the discrete members shaped or structured to reduce crack initiation and propagation within the core arrangement.
A structural system comprising;
- two or more structural panels, one or more couplers coupling the two or more structural panels together,
- each structural panel comprising a first outer sheet, a second outer sheet, and a core arrangement sandwiched between the first and second outer sheet,
- the core arrangement comprising two or more discrete members arranged adjacent each other, the discrete members shaped or structured to reduce crack initiation and propagation within the core arrangement.
A method of forming a structural panel comprising;
- providing a first outer sheet,
- providing a second outer sheet,
- providing a core arrangement, the core arrangement comprising a plurality of tubes, the tubes being bonded to each other, and the tubes being bonded to the first outer sheet and a second outer sheet, and wherein,
- the structural assembly and the core arrangement are structured to reduce the number of stress concentration locations within the core arrangement, the plurality of tubes shaped and structured to provide mechanical stiffness to the structural system and the structural system being substantially crack propagation resistant.
A core arrangement of a structural panel comprising;
- a plurality of elongate, hollow tubes arranged adjacent and bonded to each other, wherein the tubes are arranged in one or more layers, and the tubes have a circular cross section.
A method of forming a structural panel comprising;
- providing a first outer sheet,
- providing a second outer sheet,
- providing a core arrangement, the core arrangement comprising a plurality of tubes, the tubes being bonded only to the outer sheets but not to each other.
- the structural assembly and the core arrangement are structured to reduce the number of stress concentration locations within the core arrangement, the plurality of tubes shaped and structured to provide mechanical stiffness to the structural system and the structural system being substantially crack propagation resistant.
A core arrangement of a structural panel comprising:
- at least one outer sheet, and
- a plurality of elongate, hollow tubes arranged adjacent and bonded to the at least one outer sheet and arranged in one or more layers with each tube having a circular cross section.
