Mathematical Modelling of Bonded Fibre-Composite Repairs to Aircraft

Abstract

Bonded fibre-composite doublers are increasingly being used to reinforce and/or repair damaged or underdesigned metallic aircraft structure. This trend will continue as the average age of Australian civilian and military aircraft increases. Two mathematical models of the stress state in bonded doublers are presented in this report: the end-tapered double-lap joint and the stepped double-lap joint. The mathematical development of the two models is detailed and the fidelity of the predicted stress states compared with that obtained from finite element analyses and experiment.
