    摘要: A composite material, in particular for aeronautical applications, comprising: a first pre-impregnated layer having a resin-based matrix reinforced with fibres to give the first layer predefined mechanical properties; and a second layer of magnetic field intensifier material, superimposed on a face of the first layer and joined to the first layer along that face; the second layer comprises electrically conductive fibres, preferably of carbon, dispersed in the second layer in at least two directions with different orientations and having equivalent electrical resistivity, parallel to the aforementioned face, of less than 600 μΩm, preferably less than 200 μΩm and even more preferably less than 100 μΩm, so as to facilitate localized heating by electromagnetic induction; the first and second layers joined together define a lamina of super-weldable composite material.
