Radiation Testing of Composite Materials, In Situ Versus Ex Situ Effects.

Abstract

A study was conducted to investigate the effect of post-irradiation test environments on tensile properties of representative advanced composite materials (T300/5208, T3OO/934, c6ooo/P17oo). 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)
