Abstract 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 gaometry 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. La présente invention porte sur la protection d'éléments (1) en matériau composite qui sont protégés au niveau de leurs points géométriques complexes tels que les bords, les arêtes, les chants et les angles, contre les décharges électriques auxquelles ils sont potentiellement exposés. Pour obtenir ces éléments protégés (1), on applique un cycle de température et de pression à un matériau composite placé sur un moule (2) conçu de sorte que, une fois connue la géométrie de l'élément (1), le moule (2) comporte des cavités (6) libres destinées à recevoir l'accumulation de la résine utilisée dans le processus de production dudit élément (1), résine qui va assurer la protection diélectrique des bords, arêtes, chants et angles de l'élément (1) par l'accumulation sous formes de couches (3) qui restent disposées autour des bords libres de l'élément (1), conférant ainsi à ces mêmes surfaces de bords, arêtes, chants ou angles, une protection diélectrique d'isolement électrique qui évite les éventuelles décharges et l'expulsion de particules chaudes en cas de décharge électrique sur ledit élément (1). Cette invention porte également sur un processus de production d'un tel élément (1) en matériau composite.
