Abstract: Systems and methods for reinforcing a pipe. A robot is adapted for rotating in a pipe to apply resin and/or fiber to an inner surface of a pipe in a generally helical pattern. Application of resin and/or fiber to the pipe may be actively adjusted to achieve desired application. A rate at which the robot moves along the pipe per revolution of the robot can be may be adjustable. A rate at which fiber is advanced toward the inner surface of the pipe may be adjustable for application of the fiber to the inner surface of the pipe in a generally non-tensioned state.

Abstract: A method of reinforcing a structural member comprises positioning a shell around the structural member, placing a force dampening material around an exterior of the shell and securing the force dampening material around the shell. In certain arrangements, the method further includes at least partially filling a space defined between the structural member and the shell with a filler material. In some embodiments, the filler material comprises a concrete, a grout, an epoxy, combinations thereof and/or the like. In one embodiment, the shell comprises a fiber reinforced polymer (e.g., CFRP, GFRP, aramid fibers, epoxy, other resins, etc.). In alternative embodiments, the methods additionally includes placing one or more layers of fiber reinforced polymer around the shell prior to placing a force dampening material around an exterior of the shell. In some embodiments, the layer of fiber reinforced polymer comprises CFRP, GFRP or any other type of fiber reinforced polymer.

Abstract: A method of reinforcing a pipe or other structure using fiber reinforced polymer includes coating a raw carbon and/or other types of fiber roving with an epoxy or other resin, selectively directing the fiber roving through a positioning assembly of a reinforcing system, splaying the fiber roving that exits the positioning assembly onto a pipe wall or other surface, rotating the positioning assembly about an axis to place splayed fiber roving along a first circumferential section of the pipe wall or other surface and moving the positioning assembly along a longitudinal axis of the pipe or other structure to selectively place splayed fiber roving along a second circumferential section of the wall.
