Toughened epoxy resins cured by electron beam radiation

摘要

Preliminary research has determined that conventional epoxy resins can be cured by exposure to Electron Beam (EB) radiation as provided by a high energy/power electron beam accelerator to provide materials with high glass transition temperatures and mechanical properties comparable to thermally cured epoxies. A cationic photoinitiator at a concentration of 1-3 parts per hundred of the epoxy resin is required for this process.
