Abstract: As a new technology, the use of electron beam in the processing of composites has been paid a great attention in recent years. It manifests many advantages over conventional thermal curing. Doing necessary research work will take the process to a higher level. In this paper, epoxy resin F 46 which is suitable for electron beam curing is studied. Firstly, the effect of diphenyliodonium salts(DPIPF 6) content on the system is analyzed. The effect of dose on the T g  of F 46 is compared. In the end,allyl glycidyl, butyl acrylate and acetone as the diluent of the system which is appropriate for electron beam curing are investigated.

Key words: elect ron beam curing, epoxy resin, diphenyliodonium salts
