ABSTRACT:
A system and method of repairing a pipe including securing a reinforcing material, such as a dry fiber structure (e.g., a carbon fibers) to the surface of the pipe. A polymeric material is placed on top of the reinforcing material, self-penetrating the dry fiber structure. The polymeric material substantially saturates the reinforcing material and cures to form a reinforced polymeric composite which may increase or restore the pressure rating or operating pressure capacity of the pipe. Optionally, an outer containment component, such as a sleeve, shell, box, wall, outer pipe, and so on, may be installed around the reinforcing material prior to introduction of the polymeric material. In this case, the polymeric material may be placed (i.e., poured) into the interior of the containment component on top of the reinforcing material.
