The main objective of this investigation was to generate characteristic shear responses for several adhesives used for aerospace structural bonding applications. The shear responses consisted of shear stress-strain curves obtained by standardized tests and characterizing subsequent failure modes at three different environmental conditions. Six of these adhesives were film and the remaining were paste adhesive. In addition, the effects of heat and humidity on the apparent shear strength, shear modulus, and failure modes of each adhesive were investigated by testing at elevated temperatures with humidity-conditioned specimens. The characteristic shear responses were generated using the ASTM D 5656 thick adherend test method. The primary purpose of this report was to make this data available for use in future design and modeling efforts.
