Abstract : The purpose of this study was to establish the feasibility of using rational engineering methods to design bonded and mechanically fastened joints fabricated from composite and composite metal adherends. Work during this period continued on the survey of analytical design methods for bonded and mechanically fastened joints. Sample calculations were carried out for a simple lap joint and a scarf joint using a numerical method of shear lag analysis. Two surface cleaning procedures for FRP were investigated and a series of joints bonded with Narmco Metlbond 400 were fabricated and tested to determine the effect of pin layout on joint strength. Adhesive films were fabricated and tested for four different adhesives. (Author).
