Abstract: The critical parameters of electron beam to cure the epoxy resin E-44 were studied. The initiating efficiency of every photoinitiator increases with the increase of the absorbed dose. Diphenyl iodonium hexafluoroantimonate being the photoinitiator has a higher initiating efficiency, whose optimal quantity is 3%. The curing degree of the system is improved continuously with the increments of the photoinitiator content when the absorbed dose and the dose rate are fixed. The curing degree increases with raising dose rate obviously when the absorbed dose are fixed.

Key words: Epoxy resin E-44, Electron beam curing, Photoinitiator, Absorbed dose, Dose rate
