Abstract
Composite fibers are woven into helical fabric strips. These helical fabric strips wind upon one another as a helix to form a cylinder. When the helical strips are impregnated with resin, heated to the thermoset temperature of the resin, and compressed and cured, a cylindrical composite body results having the individual fibers of the body only arrayed radially or circumferentially. This structure can then be provided with sample tube apertures, usually after curing the cylindrical structure. Dependent upon the rate of differential advance of the weft threads, the woven cloth helically stacks to a cylinder of variable diameter--usually about a cylindrical central aperture in the cylinder.
