Interfacial Interaction in Composite Structures.

Abstract

The durability of epoxide adhesive bonds has been investigated under stress corrosion conditions. The following points have been elucidated. A silane pretreatment of aluminum adherends inhibits interfacial failure of amine cured epoxide resins; presoaking of unstressed epoxide bonds reduces the induction period to stress corrosion cracking; amines accelerate the normally slow corrosion of sluminum adherends; bayerite appears to be formed on the adherend crack surface as a post cracking phenomenon; and a possible mechanism for stress corrosion cracking is postulated.
