CA 2040186

A lining material for pipe lines, especially those hurried in the ground and a process for providing pipe lines therewith are disclosed, which comprises a flexible tubular film, a sheet covering the outer surface of the tubular film and a film capable of being split off covering the outer surface of the sheet, characterized in that the sheet is comprised of a fabric and a mat of fibers of high tenacity impregnated with a thickened liquid thermohardenable resin to form a fabric-fiber-reinforced composite molding sheet having a sufficient length and a width greater than the inner circumferential length of a pipe line to be treated, and that both laterally end portions of the sheet are slidably overlapped with each other to form a tube around the tubular film, the outer circumferential length of the tube being shorter than the inner circumferential length of the pipe line. The present invention is distinguished by using a specific fabric-fiber-reinforced composite molding sheet as the predominant constituent of the lining material in place of the conventional SMC and overcomes all the drawbacks in the prior arts. The lining material is particularly suited for lining sewage pipes. -1-
