A method of repairing a contoured structure is provided. The method includes forming and curing on the contoured structure an armature formed of materials that are curable at a temperature lower than a service limit temperature of materials of the contoured structure and removing the armature from the contoured structure and placing the armature with prepregs laminated thereon in an oven to heat cure the armature and the prepregs to form a repair patch.

Methods, systems, and apparatuses for repairing a composite material in situ are disclosed including maintaining and controlling the temperature of a material adjoining a composite material in situ, while the composite material is being heating during a composite material repair, such repair accomplished by positioning a heat source proximate to a first side of the composite material and positioning a thermoelectric device proximate to a structure located proximate to the second of the composite material, and substantially maintaining the temperature of the structure at a temperature that is different than a temperature of the composite material.

Disclosed is an off-the-road (OTR) tire repair system. In some embodiments, the OTR tire repair system includes a heat pad; an RFID tag coupled to the heat pad, the RFID tag including a machine-readable medium on which is stored information indicating an electrical flow parameter fault condition for the heat pad; an RFID reader configured to read the information from the RFID tag; and a control panel configured to receive the information from the RFID reader, and the control panel configured to detect, during operation of the heat pad and based on the information, presence of the electrical flow parameter fault condition.

A method for repairing a thermoplastic composite component is provided that includes: preparing at least one repair patch configured to conform with a defect region of the thermoplastic composite component, the defect region having a periphery that defines the defect region, the at least one repair patch comprising a thermoplastic composite material; providing a thermoplastic interface film configured to conform with at least a part of the at least one repair patch, the thermoplastic interface film having a melt temperature; disposing the thermoplastic interface film between a surface of the thermoplastic composite component disposed at the periphery of the defect region and the at least one repair patch; and heating the thermoplastic interface film to its melt temperature using an ultrasonic welder, and subsequently allowing the thermoplastic interface film to cool, thereby welding the at least one repair patch to the thermoplastic composite component.

A composite structure curing system employs a plurality of heaters mounted in at least one array in spaced proximity to a composite structure to be cured. A plurality of temperature sensors are mounted to sense temperature at selected locations on the structure. A control system receives an input from each of the plurality of temperature sensors and is adapted to control each of the plurality of heaters responsive to each input to establish a predetermined temperature profile on the structure during cure.
