Résumé : |
With the introduction of adhesive bonding as a replacement for mechanical fastening in aircraft structural components, the mechanical performance of these components can be improved by avoiding stress concentrations. The effect of bonded joint geometry on the stress distribution was examined and the influence of parameter variation on optimisation of the design and the efficiency of the joints was determined. It was shown that combining mechanical fastening and a structural adhesive improved the fatigue strength of a riveted joint significantly, while at the same time the assembly costs could be lowered. Adhesives could be used to manufacture laminated structures that showed better damage tolerance properties than solid monolithic materials and it was shown that by adding high strength fibres to the adhesive bondline of these laminates the fatigue and damage tolerance properties improved markedly. Examples of these structures are presented, together with the effect on weight and cost saving. |
