    • 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.

    • 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.
    • 使用通过将电能施加到设置在结构内的导电构件产生的内层热来控制混凝土结构的固化的方法。 这些导电构件包括碳纤维。 该方法还将导电的部件作为固化的成品结构中的内部加强件减少或消除了对钢筋的需要。 导电构件以各种形式提供,包括但不限于浸渍有能够刚性化和完全硬化形式的聚合物树脂基体的柔韧形式。 本发明可以与热响应剂结合使用以活化固化。 根据本发明的方法的优选实施例是混凝土结构的受控(加速或热激活)固化。 包含本文教导的电加热能力的混凝土结构也包括在本发明内。
