Abstract
A composite material and structure. The structure has a folded sheet having a rigid inner layer sandwiched between flexible outer layers. The sheet has an undulated shape with alternating summit and valley portions. Intermediate portions each extend between adjacent summit and valley portions. At least one score line extends through at least one of the flexible outer layers. The sheet is folded about the at least one score line. A method of forming a structure from a sheet having an undulated shape.
Claims21
A composite material foldable to form a structure, comprising:
- a sheet having a rigid inner layer sandwiched between flexible outer layers, the sheet having an undulated shape with alternating summit and valley portions and intermediate portions extending between adjacent summit and valley portions, the sheet having a plurality of spaced apart score lines, each score line formed parallel to the summit and valley portions and extending through at least one of the flexible outer layers, the sheet being foldable along the plurality of spaced apart score lines to form the structure, the folded structure comprising a plurality of segments, adjacent segments linked across one of the plurality of score lines, the plurality of segments defining:
- at least one cavity formed by two abutting segments and having at least one internal space defined by two spaced apart summits or valleys and their corresponding intermediate portions, and
- at least one overlap formed by two nested segments and having at least one interface defined by two contacting summits, two contacting valleys, or a valley contacting a summit and their contacting intermediate portions.
A structure, comprising:
- a composite material comprising a sheet having a rigid inner layer sandwiched between flexible outer layers, the sheet having an undulated shape with alternating summit and valley portions and intermediate portions extending between adjacent summit and valley portions, the sheet comprising a plurality of spaced apart score lines, each score line formed parallel to the summit and valley portions and extending through at least one of the flexible outer layers, the sheet being folded along the plurality of spaced apart score lines to form the structure, the structure comprising a plurality of segments, adjacent segments linked across one of the plurality of score lines, the plurality of segments defining:
- at least one cavity formed by two abutting segments and having at least one internal space defined by two spaced apart summits or valleys and their corresponding intermediate portions, and
- at least one overlap formed by two nested segments and having at least one interface defined by two contacting summits, two contacting valleys, or a valley contacting a summit and their corresponding intermediate portions.
A structure, comprising:
- a composite material comprising a sheet having at least two flexible paper layers being superimposed, the sheet having an undulated shape with alternating summit and valley portions and intermediate portions extending between adjacent summit and valley portions, the sheet comprising a plurality of spaced apart score lines, each score line formed parallel to the summit and valley portions and extending through at least one of the flexible paper layers and not all the flexible paper layers, the sheet being folded along the plurality of spaced apart score lines to form the structure, the structure comprising a plurality of segments, adjacent segments linked across one of the plurality of score lines, the plurality of segments defining:
- at least one cavity formed by two abutting segments and having at least one internal space defined by two spaced apart summits or valleys and their corresponding intermediate portions, and
- at least one overlap formed by two nested segments and having at least one interface defined by two contacting summits, two contacting valleys, or a valley contacting a summit and their corresponding intermediate portions.
