An eversion liner for lining a pipe includes an impermeable outer portion, inner and outer strength portions inside the impermeable outer portion, and a middle portion including at least one felt layer radially between the inner and outer strength portions. At least one of the inner and outer strength portions is formed from a unitary sheet of strength material that includes parallel chopped strands of fiber. The longitudinal edge margins of the sheet of strength material are positioned in overlapping engagement and joined together by joining structure. The parallel chopped fibers can be oriented transverse to the length of the liner. The joining structure can prevent reduction in a width of the overlapped edge margins as the liner expands during eversion.

A fiber laminate W is configured by laminating first to fourth fiber layers. The fiber laminate is provided with a taper section, in which the thickness changes depending on the position in the longitudinal direction. The first to fourth fiber layers are formed by discontinuous fibers and are configured with the orientation angles of the discontinuous fibers aligned in one direction. The orientation angles of the discontinuous fibers in the first to fourth fiber layers are different. In addition, the first to fourth fiber layers are provided with thickness changing sections, in which the thickness changes continuously while the density of fibers is kept constant irrespective of the position in the longitudinal direction. The taper section is configured by stacking the thickness changing sections.
