Abstract:
The effect of various levels of gamma radiation on some of the physical properties of Dacron,¹ nylon, cotton, Orion,² Fiberglas, Celanese X-36, and rayon was measured. Properties studied were flex fatigue, creep rate, melt points, stress strain, and shrinkage tension. In general, the effect of radiation is to worsen the physical properties of the cords evaluated. Some improvement was found in the case of nylon where shrinkage tension and creep rate were reduced. The relative resistance of the cords to radiation damage is apparent from the test data. Studies in both air and vacuum show that oxygen is a strong contributor to the degradation of the physical properties in the presence of radiation.
