Effect of Temperature and Reactor Irradiation on the Strength of Biaxially Oriented Polyethylene Terephthalate
Journal Article
·
· Journal of Applied Physics
Samples of irradiatsd biaxially oriented polyethylene terephthalate were investigated at five temperature levels from --l5O deg F to 350 deg F. From tensile studies, the ultimate tensile strength was found to decrease markedly to a relatively low magnitude upon receiving an irradiation dose having a thermal neutron bombardment componant of 10¹⁸ nvt and over. The modulus of elasticity for both the irradiated and nonirradiated samples was found to increase with the decrease of the temperature. The fracture surfaces of the biaxially oriented polyethylene terephthalate samples obtained at --15 deg F are recorded for reference. (auth)
