1. An electrical heating device comprising:
a support which extends along a surface, a heating layer situated on the said support, the said heating layer comprising a first electrically conducting material, the said first electrically conducting material comprising first carbon fibres embedded in a first polymer matrix, and the said heating layer configured to be connected to an electrical power supply to heat the said device,the said device being characterized in that the heating layer has a volume which comprises:
a circuit part composed of the first electrically conducting material and which extends along at least one continuous line between ends linked directly or indirectly to the electrical power supply, and an insulation part composed of a second electrically non-conducting material and which fills the remainder of the volume of the heating layer, the said insulation part electrically insulating the circuit part in the heating layer. |
