elemento de material composto, aeronave e processo de fabricação de um elemento de material composto proteção de elementos -( 1) de materiál composto protegidos eni seus pontos de geometria complexa, tais como bordas, arestas, cantos e ângulos, contra descargas elétricas às quais são potencialmente expostos, os ditos elementos ( 1) sendo obtidos com a aplicação de um ciclo de temperatura e pressão a um material composto disposto sobre um molde (2) projetado de tal forma que, uma vez conhecida a geometria do elemento (1), o molde (2) compreenda vazios (6) livres destinados ao acúmulo de resina do processo de fabricação do dito elemento (1), resina esta que irá conformar a proteção dielétrica das bordas, arestas, cantos ou ângulo do elemento (1) ao ser acumulada formando camadas (3) que são dispostas ao redor das bordas livres do elemento (1), conferindo assim a estas superfícies de bordas, arestas, cantos ou ângulos uma proteção dielétrica de isolamento elétrico que impede possíveis descargas e expulsão de partículas quentes em caso de descarga elétrica sobre o dito elemento (1). a invenção também se refere a um processo de fabricação de tal elemento (1) de material composto. Protection of elements (1) of composite material protected at its points of complex geometry, such as various edges and corners, against electric discharges to which they are potentially exposed, said elements (1) being obtained by applying a cycle of temperature and pressure to a composite material arranged in a mould (2) designed in such a way that, once the geometry of the element (1) is known, the mould (2) includes free spaces (6) intended for the accumulation of resin from the process of manufacture of said element (1), and said resin will form the dielectric protection of the various edges or corners of the element (1) as it builds up, forming layers (3) that are disposed around the free edges of the element (1), thus endowing these surfaces of various edges or corners with dielectric protection of electrical insulation that prevents possible discharges and expulsion of hot particles in the case of electric discharge on said element (1). The invention also relates to a process of manufacture of an element (1) of composite material as such.
