FATIGUE STRENGTH OF HOT CURE EPOXY RESIN ADHESIVE JOINTS AT ELEVATED TEMPERATURES

Potential applications for adhesives involving steel to steel bonding in bridge decks is considered. In steel bridges temperature extremes of 60 to 65 degrees C may occur locally, and the fatigue performance of 2 part cold cure epoxies (satisfactory from -25 to 45 degrees C) is unlikely to be adequate. This report describes a study and tests of commercially available 1 part hot cure epoxies which are shown to have superior fatigue performance at elevated temperatures, a mean shear stress range of 7.1 n/mm square at 10 to the 7th cycles being acceptable within the range from room temperature to 75 degrees C. The research was carried out for the Transport and Road Research Laboratory. (TRRL)
