Methods and apparatuses for maintaining temperature differential in materials using thermoelectric devices during hot bonded repair

A method comprising:

• positioning a heat source proximate to a first side of a composite material, said composite material having a first side and a second side, with a structure located proximate to the second side of the composite material, said structure having a first side and a second side, with the first side of the structure located proximate to the second side of the composite material;
• positioning a thermoelectric device proximate to the second side of the structure, said thermoelectric device in communication with a controller;
• contacting the second side of the structure with a temperature sensing device, said temperature sensing device in communication with the controller;
• activating the heat source;
• applying heat from the heat source to the first side of the composite material;
• heating the composite material to a first temperature;
• providing an electric current to the thermoelectric device;
• and
• substantially maintaining the temperature of the structure at a second temperature that is different than the first temperature of the composite material.
