improved protection against direct lightning strikes in riveted areas of cfrp panels

摘要

The invention relates to a metalization structure of aircraft panels and process for obtaining such structure, such that it comprise a structure of a panel (1) made in composite material, the mentioned panel (1) comprising a metal mesh or foil (2) in its outer part, said panel (1) further comprising a bore which in turn comprises a shank and an upper countersinking (8), such that the mentioned panel (1) is fixed to another structural aircraft element (3) by means of metal fixing elements (4), characterized in that said structure comprise a metallization layer (7) arranged on the upper countersinking (8), extending in the adjacent area of the metal mesh or foil (2), such that it is ensured that electrical continuity exists between the upper countersinking (8) and the metal mesh or foil (2) during the time that the lightning bolt strikes the structure of the panel (1), further ensuring that most of the current discharged by the lightning bolt is conducted over the surface of the structure of the mentioned panel (1). The invention further relates to a process for making such structure of a panel (1).
