Abstract: A liner for repairing damaged pipes, such as underground sewer or gas pipes is disclosed. The liner comprises a TPU coating on a fibrous mat of non-woven fabric. The TPU coating is a high heat resistance polyester TPU which allows an epoxy resin/amine to be saturated in the non-woven fabric and the cure initiated by the use of steam or hot water. The cured epoxy resin converts the liner from a flexible state to a rigid state as the liner is cured in place inside the pipe. The TPU containing liner may also be used with thermoset resins other than epoxy resins, such as polyester resins and vinyl ester resins.
