A careful choice of the reinforcement materials and their design is fundamental to achieve an effective design solution for fuselage stiffened panels. A test campaign has been performed to investigate the design of fuselage stiffened panels with different metallic skin concepts (monolithic vs. Metal Laminates), stringer materials and local reinforcements from aluminum, titanium and glass-fiber. Observations were made on the crack growth retardation mechanisms. Bonded doublers and selective reinforcements confirmed to be outstanding tools to improve the damage tolerance properties of structural elements with a minor weight increase. Tests results on stiffened panels show that fatigue insensitive selective reinforcements offer, in respect to standard aluminum doublers, significant improvement of the damage tolerance characteristic: longer propagation lives, or correspondingly higher allowable stress levels and enhanced residual strength performances.
