Abstract
Molded skins and methods of making molded skins are disclosed. An embodiment of a skin includes a sheet having first and second surfaces, a first arcuate portion integral with the sheet, and a second arcuate portion integral with the sheet and adjacent to the first arcuate portion. The sheet includes a cellulosic material. The first arcuate portion includes a first surface and a second surface, each having an arc. The second arcuate portion includes a first surface and a second surface, each having an arc. An angle forming the arc of the first surface of the first arcuate portion is greater than 110 degrees and an angle forming the arc of the first surface of the second arcuate portion is less than 102 degrees.
Claims42
A skin comprising:
- a sheet comprising a cellulosic material, the sheet further comprising a first surface and a second surface;
- a first arcuate portion integral with the sheet, the first arcuate portion comprising a first surface and a second surface, the first and second surfaces of the first arcuate portion each comprising an arc;
- and
- a second arcuate portion integral with the sheet and adjacent to the first arcuate portion, the second arcuate portion comprising a first surface and a second surface, the first and second surfaces of the second arcuate portion each comprising an arc, wherein an angle forming the arc of the first surface of the first arcuate portion is at least approximately 118 degrees and an angle forming the arc of the first surface of the second arcuate portion is no greater than approximately 93 degrees.
A method of making a skin, the method comprising:
- providing a sheet comprising a cellulosic material, the sheet further comprising a first surface and a second surface;
- molding a first arcuate portion integral with the sheet, the first arcuate portion comprising a first surface and a second surface, the first and second surfaces of the first arcuate portion each comprising an arc;
- and
- molding a second arcuate portion integral with the sheet and adjacent to the first arcuate portion, the second arcuate portion comprising a first surface and a second surface, the first and second surfaces of the second arcuate portion each comprising an arc, wherein an angle forming the arc of the first surface of the first arcuate portion is at least approximately 118 degrees and an angle forming the arc of the first surface of the second arcuate portion is no greater than approximately 93 degrees.
A skin comprising:
- a sheet comprising a cellulosic material, the sheet further comprising a first surface and a second surface;
- a first arcuate portion integral with the sheet, the first arcuate portion comprising a first surface and a second surface, the first and second surfaces of the first arcuate portion each comprising an arc;
- and
- a second arcuate portion integral with the sheet and adjacent to the first arcuate portion, the second arcuate portion comprising a first surface and a second surface, the first and second surfaces of the second arcuate portion each comprising an arc, wherein a ratio of a length of the arc of the first surface of the second arcuate portion to a length of a chord of the arc of the first surface of the second arcuate portion comprises a range between approximately 1.045 and approximately 1.122.
A method of making a skin, the method comprising:
- providing a sheet comprising a cellulosic material, the sheet further comprising a first surface and a second surface;
- molding a first arcuate portion integral with the sheet, the first arcuate portion comprising a first surface and a second surface, the first and second surfaces of the first arcuate portion each comprising an arc;
- and
- molding a second arcuate portion integral with the sheet and adjacent to the first arcuate portion, the second arcuate portion comprising a first surface and a second surface, the first and second surfaces of the second arcuate portion each comprising an arc, wherein a ratio of a length of the arc of the first surface of the second arcuate portion to a length of a chord of the arc of the first surface of the second arcuate portion comprises a range between approximately 1.045 and approximately 1.122.
