MATERIAL WITH UNDULATING SHAPE
A material sheet includes a sheet of material having a small undulating shape. The material sheet provides added strength or allows for reduced material thicknesses in some embodiments. Some embodiments of the material sheet are to at least partially make an appliance, siding, a stud, a motorized vehicle, an electronics enclosure, a shingle, a window spacer, or a window component.
1 . A material sheet comprising a sheet of material having an undulating shape wherein the undulating shape has a peak-to-peak period in a range from about 0.005 inches to about 0.08 inches.
2 . The material sheet of claim 1 , wherein the peak-to-peak period is in a range from about 0.02 inches to about 0.04 inches.
3 . The material sheet of claim 1 , wherein the undulating shape has a peak-to-peak amplitude in a range from about 0.005 inches to about 0.08 inches.
4 . The material sheet of claim 3 , wherein the peak-to-peak amplitude is in a range from about 0.02 inches to about 0.04 inches.
5 . The material sheet of claim 1 , wherein the material sheet has a thickness in a range from about 0.0001 inches to about 0.01 inches.
6 . The material sheet of claim 5 , wherein the thickness is in a range from about 0.0003 inches to about 0.004 inches.
7 . The material sheet of claim 1 , wherein the material thickness is in a range from about 0.01 inch to about 0.06 inch.
8 . The material sheet of claim 1 , wherein the undulating shape defines a plurality of peaks and valleys extending in a first longitudinal direction, and wherein the material sheet has increased flexibility to bending along the longitudinal direction than in the lateral direction.
9 . The material sheet of claim 1 , further comprising a coating on at least one surface of the sheet of material.
10 . An appliance at least partially made from the material sheet of claim 1 .
11 . The appliance of claim 10 , wherein the appliance is one of a refrigerator, an air conditioner, a dishwasher, a clothes dryer, a clothes washing machine, a drying cabinet, a freezer, a stove, a water heater, a trash compactor, and a microwave oven.
12 . The appliance of claim 10 , wherein the material sheet includes an undulating shape including a plurality of peaks and valleys, wherein the appliance is configured so that at least some of the peaks and valleys are generally vertically arranged when the appliance is in use.
13 . Siding at least partially made from the material sheet of claim 1 .
14 . A metal stud at least partially made from the material sheet of claim 1 .
15 . The metal stud of claim 14 , further comprising first, second, and third sidewalls.
16 . A motorized vehicle comprising a body, wherein the body is at least partially made from the material sheet of claim 1 .
17 . A shingle at least partially made from the material sheet of claim 1 .
18 . The shingle of claim 17 , wherein the shingle further comprises a first layer and a second layer facing the first layer, the first layer made from the material sheet of claim 1 .
19 . The shingle of claim 18 , wherein the second layer is asphalt.
20 . The single of claim 18 , wherein the shingle is a three-tabbed shingle.
21 . A method of making a material sheet, the method comprising: forming an undulating shape in a sheet of material, wherein the undulating shape has a peak-to-peak period in a range from about 0.005 inches to about 0.1 inches.
22 . The method of claim 21 , wherein forming the undulating shape comprises passing the sheet of material through at least a pair of corrugated rollers.
23 . A window spacer at least partially made from the material sheet of claim 1 .
24 . A window component at least partially made from the material sheet of claim 1 .
