Abstract
An architectural column includes a tubular column body having a longitudinal axis extending from a first end to a second end, at least one inner layer, at least one support layer and at least one outer layer, wherein the support layer includes a composite fabric having fibers and a bonding resin.
Claims16
A method of making an architectural column, comprising:
- forming an inner layer of a column body about a mandrel;
- forming a support layer of a column body around said inner layer;
- forming an outer layer of a column body around said support layer;
- and
- removing said mandrel;
- wherein said support layer comprises a composite fabric having fibers and a bonding resin, said support layer comprising of a pre-manufactured sheet of composite fabric, and wherein said column has a longitudinal axis extending from a first end to a second end;
- wherein said composite fabric support layer has a length substantially equal to a length of said architectural column;
- and
- wherein said fabric has a width substantially equal to a circumference of an outer surface of said inner layer wherein said composite fabric forms the support layer without creating a ridge or gap at a seam.

A method comprising:
- forming a column body including filament-winding an inner layer around a mandrel, wrapping a pre-manufactured sheet of composite fabric around said inner layer, and filament-winding an outer layer around said composite fabric;
- and
- removing said mandrel;
- wherein said composite fabric includes fibers and a bonding resin;
- wherein said composite fabric has a length substantially equal to a length of said column body;
- wherein said fabric has a width substantially equal to a circumference of an outer surface of said inner layer wherein said fabric is wrapped such that a ridge or gap is not created at a seam.
