Structural Adhesive Joints for Civil Engineering Use
Original language description
The paper reports on an experimental analysis focused on determining the mechanical characteristics of two types of acrylate adhesives applied in a double lap connection loaded by shear. The study comprises two basic substrate materials often used in façades both for cladding and for substructure – aluminium and galvanised steel. Both materials are applied with a smooth and mechanically roughened surface to compare adhesion in relation to the laboriousness of surface preparation. Except for blank aluminium, anodised aluminium was also used. Material and surface treatment has a great influence not only on adhesion and hence strength of the joint but also on failure mode, behaviour and safety of a particular joint. Moreover, every necessary surface treatment creates higher labour intensity, higher time consumption and thus increased costs. Our results showed different behaviour of both chosen acrylate adhesives in spite of their similar chemical bases. The first acrylate, two-part structural methacrylate, showed shear strength from 12 to 17 MPa in dependence on substrate material with shear strain between 0.6 and 1.2. The best adhesion was observed at roughened galvanised steel substrates. The second acrylate adhesive, two-part structural adhesive based on acrylic double performance polymer technology (ADP), proved shear strength from 8 to 9 MPa for aluminium substrates and less than 6 MPa for galvanised steel substrates. ADP adhesive also showed higher shear strain values (approx. 2.8). The experimental study proved that a choice of the adhesive has a great influence on the mechanical properties of adhesively bonded joint as well as on adhesion to a particular substrate even in the case of a similar chemical base of adhesives.
