Abstract Scope |
The main objective of this work is to define optimum values for key parameters affecting the strength of adhesively bonded Al 5052-H36 joints. These parameters are adhesive type, curing temperature, and geometrical parameters. To evaluate the effect of these parameters on the performance of bonded joints, single-lap joint coupons were prepared and tested under tension. The adhesives 852/25GB and Ep 5089, were studied to analyze the effect of the polymer type on the mechanical behavior of bonded joints. The effect of geometrical parameters and curing temperature of adhesive were investigated for joints assembled with 852/25GB. 852/25GB makes weaker joints and shows cohesive failure, while EP 5089 adhesive resulted in stronger joints and interface failure. Samples exposed to heating cycles generated the strongest joints compared to those cured @ RT and 35 ̊C. Increasing overlap length, decreasing adhesive thickness, and the presence of spew fillet improved the joint resistance. |
