Material and process for lining pipes

摘要

A lining material for pipes which comprises a flexible tubular film (1), a sheet (2) covering the outer surface of the tubular film and a removable film (3) covering the outer surface of the sheet, lateral end portions (2a, 2b) of the sheet being slidably overlapped with each other to form a tube around the tubular film. Specific fabric-fibre-reinforced composite moulding sheet comprising an outer fabric layer (4) and mat is used as the predominant constituent of the lining material in place of a conventional SMC. There may also be a non-woven soft fabric (15) at the inner surface in use. The invention includes also a method of forming linings in pipes, from such materials.
