Effects of Electron Beam and Atomic Oxygen Irradiation on Hypervelocity Impact Fracture Behavior of Polyimide CFRP
Abstract Carbon fiber-reinforced plastics are lightweight materials that have high specific strength and stiffness and are widely used in space. The space environment, including gamma rays, electron beams, ultraviolet rays, thermal cycles, and atomic oxygen, may reduce the mechanical properties of materials. In this study, hypervelocity impact experiments were conducted to examine the effects of electron beams and atomic oxygen irradiation on polyimide carbon fiber-reinforced plastic specimens. Their effects on the fracture behavior were investigated in detail by observing the perforation holes obtained after the impacts and analyzing the forward ejecta.
