Interactions between F-111 Fuselage Fuel Tank Sealants. Part I. Characterisation of Polyester Sealants and their Hydrolytic Degradation Products,

Abstract

Interactions between polysulfides and the hydrolysis products of polyester sealants EC 5106 and EC 5146 within integral fuselage fuel tanks of F-111 aircraft lead to fuel leaks. To assist in determining the mechanisms involved in this process a study of the physical changes which occur during contact of typical polysulfides with actual and model polyester products is to be undertaken. Prior to this investigation a detailed analysis of the polyester sealants was necessary to assist selection of model degradation products.
