Abstract: A system for applying a web around a cylindrical object with even tension containing a core having a generally cylindrical shape and a pair of handles. Each handle has an insertion area, a collar area, and a gripping area. The collar area is sandwiched between the insertion area and the gripping area and the insertion diameter is less than the inner diameter of the core at the first end and second end. The handles and core have a means for coupling meaning that the core and the insertion area of the handles do not move independently from one another.

Abstract: A strengthened polyethylene tubular member, where the polyethylene tubular member has an outer surface, a circumference, a wall thickness, an area to be strengthened, and the outer surface of the polyethylene tubular member contains polyethylene. The strengthened polyethylene tubular member contains a fabric layer wrapped around the circumference of the tubular member at least two full rotations and covering the area to be strengthened. The fabric layer contains a plurality of interwoven tape elements with a base layer of a strain oriented olefin polymer disposed between covering layers of a heat fusible olefin polymer. The tape elements within the fabric layer are bonded together and the tape elements adjacent the tubular member are bonded to the tubular member.

Abstract: A fabric device for application on a degraded area of a member for rehabilitating the member. A fabric device in accordance with the present invention comprises at least one layer of composite fabric, which has a first surface and a second surface spaced-apart from the first surface, nanomaterial on at least one surface of the fabric, and a resin matrix on the fabric over the nanomaterial. The resin matrix may also comprise nanomaterial therein.

Abstract: A method of repairing a polyolefin structure at a damaged area thereof containing applying a filler material as necessary to fill the damaged area, overlaying the filled damaged area with a transitional film having a first side adapted to bond to polyolefins, bonding the transitional film to the polyolefin structure, and applying a reinforcement system over the transitional film. The bonding of the transitional film to the polyolefin structure comprises applying heat to the transitional film. A repair system for repairing a polyolefin structure containing optionally a filler material on the polyolefin structure, a transitional film applied over and bonded to the polyolefin structure having a first side adapted to bond to polyolefins, and a reinforcement system, applied over the transitional film. The reinforcement system contains a fiber-reinforced polyurethane system bonded to the second side of the transitional film.

Abstract: A repair system for repairing a polyolefin pipe containing a transitional film applied over and bonded to the pipe and a reinforcement system, applied over the transitional film. The transitional film has a first side adapted to bond to polyolefins and the reinforcement system contains a fiber-reinforced polyurethane system bonded to the second side of the transitional film. A system two polyolefin tubular members joined end-to-end containing two tubular members arranged such that their respective ends are adjacent, thereby defining a circumferential joint, a transitional film applied and bonded to the circumferential joint and at least a portion of the two tubular members, and a reinforcement system applied over the transitional film. The transitional film has a first side adapted to bond to polyolefins and the reinforcement system contains a fiber-reinforced polyurethane or a fiber-reinforced epoxy system bonded to the second side of the transitional film.
