Abstract

Abstract Translated from French Le boîtier de protection comporte une embase (2) et un capot (4) fixé sur l'embase, formé d'une structure mécanique rigide (14) en matériau composite constitué d'une résine renforcée par des fibres, d'un matériau de protection (16) contre les rayons X recouvrant en partie la surface externe de la structure mécanique, ce matériau de protection X étant formé d'une matrice en résine renfermant une poudre d'un métal de numéro atomique au moins égale à 47 et de température de fusion au moins égale à 630 C, d'un matériau (20a) formé d'un élément de numéro atomique faible formant la surface externe du capot, et éventuellement d'un matériau conducteur de l'électricité (22) recouvrant la surfaçe interne de la structure mécanique. Application aux circuits électroniques embarqués sur aéronef. The protective housing comprises a base (2) and a cover (4) fixed to the base, formed of a rigid mechanical structure (14) made of composite material consisting of a fiber-reinforced resin, a material of protection (16) against X-rays partially covering the external surface of the mechanical structure, this protective material X being formed from a resin matrix containing a powder of a metal with atomic number at least equal to 47 and of temperature of melting at least equal to 630 C, of a material (20a) formed of an element with a low atomic number forming the external surface of the cover, and possibly of an electrically conductive material (22) covering the internal surface of the mechanical structure. Application to electronic circuits on board aircraft.
