Resumo: Adhesively bonded joints have been increasingly applied in primary aerostructures, mainly due to their numerous advantages over mechanically fastened joints. More specifically, bonded Tjoints made from carbon fibre reinforced plastics (CFRPs) are commonly found as stiffening members on wing paneis and fuselage sections. Despite the well-known advantages of composites, aluminium stiffeners can yet be considered a safer and more conservative solution, since composite T-joints face delamination problems that typically initiate at the central noodle of the stiffener - the part where the three arms of the stiffener come together - and propagate through the adhesive bondtine.

[...]As juntas adesivas têm sido cada vez mais utilizadas em estruturas aeronáuticas primárias, principalmente devido às suas numerosas vantagens em relação a juntas rebitadas ou aparafusadas. Particularmente, juntas em "T" compósitas de matriz polimérica e reforçadas com fibras de carbono (CFRP) são frequentemente encontradas como membros enrijecedores (stifteners) em painéis de asas e seções de fuselagem. Apesar das vantagens bem conhecidas dos materiais compósitos, as juntas em "T" em alumínio ainda podem ser consideradas uma solução mais segura e conservadora, visto que as juntas em "T" compósitas enfrentam problemas de delaminação que normalmente se iniciam no preenchimento central do enrijecedor - a parte onde a alma e o banzo se juntam - e propagam-se ao longo da conexão adesiva.
