Patent ID: 7473870

Claim:
A process for manufacturing a radiation heating structure, the structure comprising: a heating layer comprising at least one electrical resistor intended to be electrically powered in order to produce Joule heating; a radiating layer; and a substantially thermally insulating layer, the insulating layer and the radiating layer being fixed on either side of the heating layer, wherein: a) a laminate comprising at least said electrical resistor and reinforcements is introduced into a mold; and b) injected into the mold; via an opening formed in a first wall of the mold opposite one face of the laminate intended to form the radiating layer, is a first resin that is filled with radiating additives and can be cured in the mold; and via an opening formed in a second wall of the mold opposite one face of the laminate intended to form the insulating layer, is a second resin that is more fluid than the first resin and can be cured in the mold.
