Abstract

The article presents the analysis of the impact of surface roughness on the load capacity of lap adhesive joints from aluminum alloy 2024. The surfaces of the samples were prepared to bond using mechanical treatment methods, such as milling and abrasive blasting. The surface roughness of the samples for different pre-treatment variants, measured in the 2D system, was found in the range of: Rp=19,4÷60,6 [μm], Rv=16,5÷88,1 [μm], Rz=35,9÷147,0 [μm], Rc=32,2÷103,3 [μm], Rt=37,1÷174,7 [μm], Ra=8,91÷22,73 [μm], Rq=10,50÷27,33 [μm], Rsk=-0,2260÷0,6487, Rku=1,78÷5,85, RSm=0,1207÷0,7337 [mm], Rdq=23,4÷198,7 [˚]. Strength tests showed an increase in the bearing capacity of joints the surfaces of which were subjected to both milling and abrasive blasting.
