Title:
COMPOSITE MATERIAL AND METHOD FOR PRODUCING THE SAME
Document Type and Number:
WIPO Patent Application WO/2020/129007
Kind Code:
A8
Abstract:
A composite material, in particular for aeronautical applications, comprising : a first pre- impregnated layer (2) having a resin-based matrix (3) reinforced with fibres (4) to give the first layer (2) predefined mechanical properties; and a second layer (6, 6') of magnetic field intensifier material, superimposed on a face (5) of the first layer (2) and joined to the first layer (2) along that face (5); the second layer (6, 6') comprises electrically conductive fibres (7), preferably of carbon, dispersed in the second layer (6, 6') in at least two directions with different orientations and having equivalent electrical resistivity, parallel to the aforementioned face (5), 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 (2; 6, 6') joined together define a lamina (L, L' ) of super- weldable composite material.
