Epoxy/graphite fiber polymide/graphite fiber, and polysulfone/graphite fiber composites were exposed to 1.33 MeV ..gamma.. irradiation and 0.5 MeV electron bombardment for varying periods of time. The effects of the irradiation treatments on the breaking stress and Young's modulus were studied by a three point bending test. Effects were small; indeed, both electron radiation up to 5000 Mrad and ..gamma.. radiation up to 350 Mrad resulted in slight increases in both stress and modulus.
