Title: DRY LINERS FOR PIPE REPAIR AND METHODS FOR MANUFACTURING DRY LINERS
Abstract:
A method of manufacturing a dry liner for reinforcing a pipe includes spirally winding a glass fiber-reinforced, continuous material around a mandrel such that a subsequent layer of the glass fiber-reinforced, continuous material at least partially overlaps a preceding layer of the material to form an overlapping region and affixing the subsequent layer of material to the preceding layer of material in the overlapping region prior to impregnating the dry liner with a resin to form a CIPP liner.
