Abstract
A composite fabric includes: a fabric backing; an adhesive layer; a midlayer barrier bonded to the fabric backing by the adhesive layer; and an external barrier bonded to the midlayer barrier, wherein the composite fabric has a hydrostatic pressure resistance of at least 100 psi and is sufficiently flexible such that it can be formed into a tube and everted. A process and an apparatus for producing the composite fabric are also disclosed. The composite fabric is particularly suitable for use as a liner in a cured-in-place pipe repair method.
