A helical textile of uniform thickness having uniform radial weft fibers from a textile ID to a textile OD; and non-interlaced circumferential warp fiber bundles having equal width and height that increases from the textile ID to the textile OD, thereby forming a helical textile having a uniform thickness from textile ID to OD. Other embodiment includes non-interlaced circumferential warp fiber bundles having an equal cross section area, a height that increases from the textile ID to the textile OD, and a width that decreases from textile ID to textile OD. Yet another embodiment includes a helical textile of a uniform thickness having circumferential warp fibers; and more than one radial weft fiber bundles, each radial weft fiber bundle occupying a zone between two selected radial distances between the textile ID and OD, wherein the cross sectional areas of the radial weft fiber bundles increases from helical textile ID to OD.
