Abstract

La présente invention concerne une résine isolante utilisée comme résine d'imprégnation pour des tissus à base d'aramide. La résine isolante comprend comme composants accessoires, outre une résine époxyde cycloaliphatique, une résine époxyde d'ester de glycidyle, ce qui permet d'obtenir des pièces isolantes résistant à la fissuration et présentant simultanément une température de transition vitreuse élevée.
