Abstract

Epoxy resin samples modified with oxide nanofillers were subjected to the action of gamma radiation for the assessment of stability under hard conditions of operation. The presence of titania (anatase) and silica influences the thermal stability of basis The rates of oxidation evaluated by chemiluminescence characterize the long term service of aged material The difference in the filler effect on the progress of oxidation can be explained on the scavenging behavior of oxides.

Keywords
