EFFECT OF $gamma$-IRRADIATION ON STRENGTH OF ORIENTED POLYETHYLENE. Technical Report No. 13
Technical Report

OSTI ID:4808237
Oriented samples of polyethylene irradiated by gamma -rays were investigated at room temperature. On the basis of tensile studies both the ultimate strength and the modulus of elasticity are found to increase as the degree of orientation increases. But the ultimate strength decreases as the dose of gamma -irradiation increases while the modulus of elasicity increases. The combined effects seem to indicate hat thie gamma -irradiation essentially destroys the molecular orientation and thus reduces the ultimate strength for either uniaxially or biaxially oriented samples.
