Adhesively bonded lap joints from pultruded GFRP profiles. Part II: joint strength prediction

Probabilistic strength prediction for double lap joints composed of pultruded GFRP profiles – Part II: Strength prediction

“…In some investigations [4][5][6] this approach has given good results, even for initially uncracked joints. However, other authors [7][8][9] reported sudden and brittle failure for GFRP joints without a detectable crack initiation and propagation phase prior to failure. In such cases, the application of the FM approach becomes difficult or even impossible.…”

“…Keller and Vallée [8,9] have presented a method to predict the strength of adhesively bonded lap joints composed of GFRP adherends subjected to axial tensile loading. The method is based on a quadratic failure criterion that considers the through-thickness tensile and shear stress interaction at the observed failure location in the mat layers of the adherends at a depth of 0.5-1.5 mm from the surface.…”

Effects of Bonded Splice Joints on the Flexural Response of Pultruded Fibre Reinforced Polymer Beams

“…Furthermore, as is clear from [3,4], most research on bonded PFRP joints has been concerned with their behaviour in tension. Flexural behaviour of bonded PFRP joints remains to be addressed.…”

“…Despite the existence of useful information on bolted tension and beam-to-column joints [1,2] and bonded tension joints [3,4], improved understanding of the behaviour of PFRP joints is still required. This is mainly because PFRPs are orthotropic elastic brittle materials with low throughthickness strength.…”

Mechanical Behaviour of Adhesive Joint under Tensile and Shear Loading

“…Regarding to the adhesively-boned joint, lots of researches focus on mechanical behaviours of adhesively-bonded joints have been conducted in aerospace engineering, but the results cannot be directly inherited to civil infrastructures, due to the essential differences: bond geometries (adhesive and adherend thicknesses), fabrication processes, loading, curing conditions and service environment. Recently, some researches [5][6][7] were conducted for civil engineering applications, focusing on the mechanical performance of adhesively bonded single-lap joints and double-lap joints. These adhesive joints composed of pultruded GFRP composite profiles glued by epoxy adhesives.…”
