The adhesively bonded joints and the mechanical joints between structural components made bycomposite materials or between elements made by composite and metal, are commonly used indifferent fields of modern industrial design and manufacturing, since they are characterized byeconomy, reliability and ease of assembly.The bonded joints are characterized by high stiffness and fatigue life, although delaminationphenomena localized near the edges of attack of the adherends may limit their use, especially inparticular applications where corrosive environments and humidity can lead to premature failure. Inthese cases, a possible alternative is offered by the well known riveted joints. On the contrary, theriveted joints require a preliminary drilling of the elements to be joined and, consequently, may causelocalized material damage, especially in presence of strongly anisotropic laminates which arecharacterized by high stress concentration.In the present work a numerical and experimental study of hybrid double-lap joints between aluminumand CFRP laminates, have permitted to highlight both the static and the fatigue performance of suchjoints, also with reference to the particular damage mechanism of the adhesive layer and to theinterlaminar damage of the CFRP, due to the riveting process.
