A seamless tubular liner for repairing an underground or surface pipe is disclosed, including circumferential wefts consisting of slivers comprising a plurality of staple fibers bundled together, the slivers adapted to elongate through disentanglement of the bundled staple fibers when the seamless tubular liner is subjected to an inflation pressure such that the diameter of the tubular liner is able to expand to accommodate variations of diameter of the pipe being repaired.

Composite panels and methods of preparation are described herein. In some embodiments, the composite panel can include a first fiber reinforcement, a polyurethane composite having a first surface and a second surface opposite the first surface, wherein the first surface is in contact with the first fiber reinforcement; and a cementitious material adjacent the first fiber reinforcement opposite the polyurethane composite. The polyurethane composite can be formed from (i) one or more isocyanates selected from the group consisting of diisocyanates, polyisocyanates, and mixtures thereof, (ii) one or more polyols, and (iii) a particulate filler. The fiber reinforcement can be formed from a woven or non-woven material, such as glass fibers. The composite panel can further include a material, such as a second fiber reinforcement and a cementitious layer, in contact with the second surface of the polyurethane composite. Articles comprising the composite panels are also disclosed.

The present invention provides an improved pole assembly. According to a first preferred embodiment, the present invention includes a first pole section which is formed by an inner shell wall surrounding a hollow inner cavity. According to a further preferred embodiment, the inner shell wall is formed as a first column of a given shape, which is formed of galvanized steel or fiberglass reinforced polymer, and which is surrounded by a center fill layer. The center fill layer is preferably formed of SSC concrete which surrounds the inner shell wall. According to a further preferred embodiment, the present invention preferably further includes an outer shell wall which is formed as a second column of a given shape, which surrounds the center fill layer.
