Radiation durability of polymeric matrix compositesThe combined effects of thermal cycling and high-dose electron irradiation on the mechanical properties of laminated graphite/polymeric CFRPs are investigated experimentally. The test apparatus and procedures are briefly described, and the results are presented in extensive tables and graphs. It is found that electron radiation produces similar significant reductions in the glass transition temperatures of the neat resins and CFRPs. The radiation-induced degradation products tend to plasticize the matrix at high temperature but embrittle it at low temperature.
