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.
