Abstract

Sont décrits des composites comprenant des couches adjacentes d'une couche hydrophobe microporeuse et d'une ou de plusieurs couches de support. Ces composites sont susceptibles de résister à la pressurisation après exposition au rayonnement ionisant. Ces composites bicouches comprennent: a) une couche de tissu métallique ou de matériau polymère organique synthétique tissé, et b) une membrane polymère hydrophobe microporeuse. Les composites à tricouches comprennent: a) un matériau polymère organique synthétique présentant, après irradiation, un allongement inférieur à 25 % après 100 heures sous une charge de 2,0 livres par pouce, b) un matériau polymère organique synthétique élastique, et c) une membrane polymère hydrophobe microporeuse. Sont décrits des dispositifs renfermant un des composites décrits et un moyen de retenue qui assure une relaxation de contrainte au niveau du bord de support.
