Abstract

Adhesion induced by homogeneous low voltage EB-irradiation (HLEBI) under O₂ partial pressure from 0.02 mol% to 20 mol% in N₂ gas atmosphere of CFRP/Al lamination has been successfully developed. Its adhesive tensile shear strength of CFRP/Al with 0.30 MGy-HLEBI under optimal O₂ partial pressure in N₂ atmospher of 0.2 mol% is 8.2 MPa, which is about 1.4 times higher than that (5.9 MPa) of CFRP/Al untreated.
