Composite material and a composite element with this is securely 'electrical continuity, process for its preparation and its use in aircraft industry

摘要

The invention relates to an element made of composite material comprising an organic matrix reinforced with mineral or organic fibers as well as at least one assembly (10) with partial overlap of at least two elongated members (7) electrically conductive, the assembly essentially embedded in the matrix in order to ensure electrical continuity through the element, at least one junction piece (1) with a conductive coating (6) or of metal or alloy conductor being interposed between the superimposed portions (8) of said elongate members (7) of each assembly (10) and kept in permanent contact with these portions (8) in the composite material by weld linking piece (1) to the elongate members (7) and preferably carried out during the heat treatment of the formation of the composite element.
