A Technique for Assessing the Durability of Structural Adhesives

Abstract

A new method for inexpensively evaluating the durability of a large number of adhesives was developed and evaluated. This test method enables an investigator to simultaneously evaluate many adhesive-adherend variations and to estimate the durability of the variations under conditions of load, temperature, and humidity. The method will save time and money in the screening process used to select the best adhesives and adherend surface treatments for a particular application. The method involves determining the residual strength after the bonded joints are immersed in 60 C water for prescribed periods of time. Data are presented for twelve structural adhesives which are 121 C (250 F) curing systems. The adherends used were 2024T3 aluminum, either acid-dichromate (FPL) etched or anodized, 6 Al-4V titanium and commercially pure (CP) titanium, both phosphate-fluoride etched. (Author)
