    摘要: A tubular member having a liner adhesively affixed to an inner surface thereof. The liner comprises a porous material formed from a plurality of needle-punched unwoven fibers so as to have a pair of oppositely facing surfaces. The liner also includes a first mat of finespun woven filaments of glass defining an inner surface thereof and a second mat of finespun woven filaments of glass defining an outer surface thereof. The inner and outer surfaces of the liner, formed by the first and second mats, are generally coextensive with the porous material. The liner also includes the first mat being secured to an inwardly facing surface of the porous material and the second mat being secured to an outwardly facing surface of the porous material. The liner is adhesively impregnated so as to adhesively bond the outer surface of the liner to the inner surface of the tubular member. Further, a method of lining a tubular member by adhesively bonding a liner to the tubular member is disclosed.

    摘要: The apparatus of the present invention is generally characterized by a heating/inflation module having pressurizable interior and an attached heat curable pre-preg. In particular, an elastomeric, seamless composite is provided that includes a heating element disposed within a thermoset resin matrix. The composite adapted to maintain a consistent temperature profile and an internal air pressure. A first end piece is attached to a first end of the composite and has an air port for communication with a compressed air source, a vacuum port for communication with a vacuum supply source and at least one electrical cable port for communication with a power supply source. A second end piece attached to a second end of the composite. The apparatus further includes a pre-preg removably attached to an outer surface of the composite. The pre-preg includes a structural fiber matrix supporting a heat curable resin. The composite is constructed by applying a liquid silicone matrix to at least one layer of braided or wound and/or tape fibers, wherein a portion of the fibers are electrically conductive. The layer of braided fibers is introduced into a mold, and a removable, expandable inner bladder is then loaded into the mold. The inner bladder is inflated to conform the layer of braided fibers to an interior surface of the mold. An electric current is caused to flow to the conductive fibers to cure the silicone matrix into a stable, elastomeric state. The composite is removed from the mold. A method for repairing a damaged section of a conduit is also disclosed.

    摘要: A method of controlling the cure of concrete structures using intralaminar heat generated by applying electrical energy to electrically conductive members disposed within the structures. These conductive members include carbon fibers. The method further incorporates the electrically conductive, members as internal reinforcement in the cured, finished structure reducing or obviating the need for reinforcing steel. The electrically conductive, members are provided in various forms including but not limited to, pliable forms impregnated with a polymer resin matrix capable of being rigidified and completely rigidified forms. The invention may be used in conjunction with heat responsive agents to activate curing. A preferred embodiment of the method according to the invention is a controlled (expedited or heat activated) cure of a concrete structure. Concrete structures containing the electrical heating capability taught herein are also included within the invention.
