Abstract
The fate and consequences of gas, released suddenly when specimens are warmed following low temperature irradiation, is not yet fully understood. In order to assess the post irradiation release or trapping of gas, the permeability of composite panels to hydrogen, carbon dioxide and carbon monoxide has been measured at room temperature at a range of pressures. In addition, changes in physical dimensions and elastic modulus of woven S2 glass/epoxide resin composites, in a direction normal to the glass fabric layers, were assessed following irradiation at 5K to a fast neutron fluence of 5 x 1021/m2. Specimens were prepared, using vacuum impregnation techniques and employing epoxide resins cured with an acid anhydride and a liquid aromatic amine. Other samples were prepared from pre-impregnated fabric using a solid aromatic amine hardener. The resin, glass and void content was measured on each sample after irradiation, measurement and testing and compared with results obtained on non-irradiated replicate specimens. The data are compared with results of a recent study of the amount of gas evolved from various resin systems during irradiation.
