Abstract:

A study was conducted to investigate the effect of post-irradiation test environments on tensile properties of representative advanced composite materials T3005208, T3OO934, c6oooP17oo. Four-ply -45-45 laminate tensile specimens were exposed in vacuum up to a bulk dose of 1 x iO0rads using a mono-energetic fluence of 700 keV electrons from a Van de Graaff accelerator. Post-irradiation testing was performed while specimens were being irradiated in situ data, in vacuum after cessation of irradiation in vacuo data, and after exposure to air ex situ data. Room temperature and elevated temperature effects were evaluated. The radiation-induced changes to the tensile properties were small. Since the absolute changes in tensile properties were small, the existence of a post- irradiation test environment effect was indeterminate. AN
