Aging irradiation of polymers. Dose-rate and test sequence influence

Creators

Description

This work brings up results of the irradiation dose-rate influence on mechanical and electrical properties of technical polymer materials evolution. Polymer samples were subjected to 3.3.10-2 Gy.s-1 and 2.8.10-1 Gy.s-1 dose-rate. Heat and radiation simultaneous action is usualy simulated sequentialy. The hardest simulation on the polymer is the sequence of irradiation followed by thermal aging not the reverse. This study was carried out on eight polymer materials among those used in the electrical appliances for P.W.R. nuclear power plants

Abstract (French)

On etudie dans ce travail l'influence de la dose d'irradiation sur l'evolution des proprietes mecaniques et electriques des polymeres. Les echantillons ont ete soumis a des debits de dose de 3,3.10-2 Gy.s-1 et 2,8.10-1 Gys-1. L'action simultanee des radiations et de la chaleur est simulee generalement par cycles successifs. Le cycle d'irradiation suivi du vieillissement thermique est plus severe que l'inverse. Cette etude a ete effectuee sur 8 polymeres utilises dans du materiel electrique pour les centrales PWR
