Improvement of Charpy Impact of Carbon Fiber Reinforced Polymer by Low Energy Sheet Electron Beam Irradiation

Effects of sheet electron beam irradiation under low potential on the Charpy impact value of carbon fiber reinforced polymer (CFRP) have been investigated. The irradiation, which is one of short-time treatments, enhances the impact value of CFRP. It probably depends on the enhancement of interfacial force, as well as the strengthening of carbon fiber and polymer.
