Irradiation effect of gamma rays on cyanate ester/epoxy resins, 3

Idesaki, Akira; Uechi, Hiroki*; Hakura, Yoshihiko*; Kishi, Hajime*

Effects of gamma-ray irradiation on a cyanate ester/epoxy resin composed of dicyanate ester of bisphenol A (DCBA) and diglycidyl ether of bisphenol A (DGEBA) was investigated by changes in physicochemical properties such as gas evolution behavior, change in chemical structure, and so on, after the gamma-ray irradiation with dose of 100 MGy as maximum under vacuum. It was found that ether linkages are mainly decomposed by the gamma-ray irradiation with evolving gases of hydrogen, carbon dioxide and carbon monoxide and decreasing in glass transition temperature.
