Abstract:

The strength properties of Textolite, Ftoroplast 4, and AMAN 7 on gamma irradn. are studied. With increasing dose of irradn., the strength at break and compression decreases. The water permeability of the sample decreases, and the heat stability and oil stability are not changed at doses of 2 times 10 super 8 rads. The Ftoroplast 4 samples showed decreased strength at break, and the specific weight of the samples was unchanged. The samples based on AMAN 7 showed good radiation stability, with the strength at break unchanged at doses of 2 times 10 super 8 rads. Strength at break increases somewhat at 5 times 10 super 7 rads, and the specific weight of the samples is not dependent on the irradn. dose. Author
