Abstract
A technique for forming a pipe flange having radial reinforcement in at least the annular portion of the bolt circle uses a specially woven band of fibers. The woof fibers in the band are longer than the width of the warp fibers so that as the band is wound into the slot of a mandrel, the tails of the woof fibers bend and extend in a radial direction.
