摘要： A tubular liner for the rehabilitation of pipelines or canals, a cured liner, a process for manufacturing a liner, the use of said liner, a process for rehabilitating pipelines or canals and a rehabilitated pipeline or a rehabilitated canal, respectively. The tubular liner includes resin-impregnated fibrous layers, wherein at least one of the resin-impregnated fibrous layers is a transverse fibrous layer which mainly includes fibres arranged at an angle in a range from 45 degrees to 135 degrees with respect to the longitudinal direction of the tubular liner.

摘要： A process for rehabilitating hydrogen lines or converting a line to the transport of hydrogen and a use of a liner for rehabilitating hydrogen lines or for converting a line to the transport of hydrogen. The liner includes at least one fibrous layer impregnated with a resin system. The liner includes a hydrogen barrier layer including at least one material selected from the group consisting of a polymer, metal, oxide, nitride, carbide, graphene, and a mixture thereof.
