Abstract

La présente invention concerne la protection contre les rayonnements ionisants, et porte en particulier sur des matériaux composites de protection contre les rayonnements et sur des procédés de production de ces matériaux. Le matériau composite de la présente invention contient entre 48 et 50 % en masse de fils de verre ; entre 11,9 et 12 % en masse d'une charge à base de métal finement dispersée ; entre 35 et 37 % en masse d'un liant, le reste étant composé d'un fluidifiant. On utilise, comme liant, une résine phénol-formaldéhyde et comme fluidifiant, un mélange d'alcool et d'acétone. Le matériau comprend, comme base de renfort, des fils de verre dont le rapport de la longueur sur le diamètre est égal à 8:11. Le procédé de production de ce matériau composite consiste à mélanger le liant, la charge à base de métal finement dispersée et les fils de verre puis à introduire le fluidifiant. Le mélange ainsi obtenu est mélangé jusqu'à ce qu'il soit homogène, puis il est versé dans un moule et soumis à un pressage à sec à une température comprise entre 160 et 180 °C. Le matériau de la présente invention procure une protection efficace contre les rayonnements ionisants. Par ailleurs, le procédé de production de ce matériau n'est pas très onéreux.
