Experimental analysis of lap binder joints with the addition of fumed silica subjected to tension has been done by varying the overlap length. The adherends have been selected as Aluminium and Stainless Steel. Binder material used is single component system phenolic resin. The thickness of the aluminium sheet was 1.63 mm and thickness of SS sheet was 2 mm, which were used as adherends. The adherends were prepared utilizing water jet cutting machine. Fumed silica was used as additive for

The mechanical properties of shear strength and tensile strength of single lap joint were studied. The adherend surfaces were prepared by mechanical abrasion method, so as to provide better contact area for the binder. The prepared joints were tested on the universal tensile testing machine (Instron 1195). The study is focused on the effect of overlap length on a single lap joint prepared by phenolic resin binder with incorporation of additives. These results were compared with the specimens when no additives were used. Obtained results would be very important for the development of important assembly products looking forward towards reduction in weight as well as cost.
