Abstract
A multiple layer hollow cylinder is provided. An inner air-tight material is wrapped about at least a portion of a mandrel to form a plurality of first material loops. Each first material loop subsequent to an initial first material loop at least partially overlaps a previous first material loop. A resin-infused fabric material is wrapped over the inner air-tight material to form a plurality of second material loops. Each second material loop subsequent to an initial second material loop at least partially overlaps a previous second material loop. An outer air-tight transparent material is wrapped over the resin-infused fabric material to form a plurality of third material loops. Each third material loop subsequent to an initial third material loop at least partially overlaps a previous third material loop. Energy is directed about the outer air-tight transparent material to cure the resin-infused fabric material to form a hollow cylinder.
