Interfacial Interaction in Composite Structures.
Abstract
With the increasing use of polymeric materials both as adhesives in bonded structures and matrices in composites, growing interest and concern has been forthcoming in recent years over the role that the interface plays in the determination of structural strength. The program reported herein has been concerned principally with the mode of failure of epoxide-aluminum bonds and epoxide-silane-aluminum bonds. Variables have been minimized in these particular investigations to allow the study of the effect of silane concentration on bond durability. The above has been accomplished by using constant rate-of-change-of-compliance adherends (i.e., tapered cantilever beams), a specific epoxide system with fixed type and content of hardener, fixed bond thickness, and invariant test specimen preparation technique, and constant temperature test conditions.
