Leitura o relatório TSB sobre Naquela época, o leme de um A310 voou no galinheiro, Me deparei com esta informação de segundo plano (seção 1.12.9.1, História dos lemes plásticos reforçados com fibra de aramida do projeto anterior):
In the earlier design of the rudder, GFRP [glass-fibre-reinforced plastic] was used as the bridging layer between honeycomb and CFRP [carbon-fibre-reinforced plastic] only in the reinforced region around the hydraulic actuators. Elsewhere, AFRP [aramid-fibre-reinforced plastic] was used. The AFRP system resulted in poor bond strength of the interior skin. Those rudders experienced large in-service disbonds of the inner skins. [...]
O que tornou os lemes A300 / A310 usando AFRP tão propensos a delaminar a pele do leme da estrutura estrutural subjacente?
