Abstract
The present invention relates to a multilayer composite material comprising: —a base layer—a metallic layer consisting of an insulating matrix phase and of a metallic particles phase, said metallic particles being distributed in the insulating matrix, wherein a volume fraction φ being the ratio between the volume of metallic particles and the volume of the metallic layer corresponds to a critical volume fraction φ*+δφ, with 0<δφ≦5%, the critical volume fraction φ* being the volume fraction for which an increase of conductivity of the metallic layer as a function of the volume fraction φ has a maximum value.
