Epoxy resins are the most important thermosetting polymers widely used as matrices in reinforced composites, adhesives in the aerospace industry, surface coatings, etc. The effects of a radiation dose on the curing of epoxy resins were investigated. Diglycidyl ether of bisphenol-A as epoxy resins, and triarylsulfonium hexafluoroantimonate as initiators were used in this study. The mechanical characteristics of the irradiated epoxy resins were compared after a curing with a gamma ray irradiation up to 500 kGy in nitrogen and air atmospheres. The thermal properties of the cured epoxy were investigated using DMA and TGA. Mechanical properties such as the flexural strength were measured. |
