摘要： A method of manufacturing a liner for reinforcing a pipe includes providing a continuous first reinforcing fibers extending in a first direction, moving the first reinforcing fibers in a machine direction such that the first direction is parallel to the machine direction, providing sheets of a material having second reinforcing fibers extending in a second direction, placing the sheets onto the moving first reinforcing fibers such that the second direction is substantially perpendicular to the first direction, and folding the sheets into a closed shape.

摘要： A continuous fabric for use in forming a repair liner for reinforcing a pipe. The fabric includes a top layer and one or more bottom layers. The width of the top layer is less than the width of the continuous fabric and the density of the top layer is less than the density of at least one of the at least one or more bottom layers. The top layer may serve as a guide for winding the fabric in an overlapping pattern about a mandrel so that the essentially only the top layer is visible in the fabric winding.

摘要： 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.
