Abstract
Adhesive 2-layer lamination joints (18-8/CFRP) were prepared using a new adhesion method consisting of applying low dose (0.13 MGy) of homogeneous low energy electron beam irradiation (HLEBI) to both 18mass%Cr-8mass%Ni austenite stainless steel (18-8), and carbon fiber reinforced epoxy polymer (CFRP) prior to hot-press in vacuum below 1 Pa for 2 h at 401±0.5 K after lamination assembly. Although, application of 0.13 MGy HLEBI dose improved the tensile shear strength (τ_B) of the 18-8/CFRP joint 162 % at accumulative probability (P_s = 0.58) from 4.5 to 7.2 MPa. In addition, the τ_<B(s)> of 18-8/CFRP with the lamination method 0.13 MGy is slightly and much higher than that of 0.13 MGy-irradiated 18-8 and untreated CFRP prior to hot-press after the assembly, respectively.
