Abstract
A reinforcement liner and methods of manufacturing the liner are disclosed. The liner includes a fabric material having first and second support layers. Each of the layers includes reinforcing fibers. The first and second support layers are oriented in different directions to provide support to the liner in those directions. The liner includes a stitching material that is used to couple the first and second support layers together. The stitching material is preferably an elastic yarn. One of the support layers includes long, chopped strands that are oriented parallel to each other. The long, chopped strands are directed so that they are in the peripheral direction of the finished reinforcement liner. The long, chopped fibers can be distributed continuously or only along portions of the width of the fabric. The disclosed methods of manufacturing a liner include alternative processes by which the liner can be made. The fabric is manufactured in the form of a continuous roll. One method involves winding the roll in a helical pattern about a fixed mandrel. Another method involves mounting several rolls circumferentially about a mandrel. The rolls are mounted so that strips of fabric from each roll overlap a portion of adjacent fabric strips to provide a continuous liner surface on the mandrel.
