Abstract:

Tensile-shear, butt-tensile, and impact tests were run on a series of adhesives from -423 to 78F. Pi-tension, plate-shear, and fatigue tests were run on a series of sandwich honeycomb panels having stainless steel and titanium faces, fiberglass honeycomb core, bonded with epoxy-nylon and filled epoxy- phenolic adhesives. The effect of primers, cleaning cycles, thermal cycling, and loading rates on the tensile-shear strength of adhesives was determined at cryogenic temperatures. Thermal expansion and tensile testing was conducted on molded and cast adhesives from -423 to 78F. Infrared curves were run on the adhesives evaluated.
