Abstract : Toughness-transition-temperature behavior for several high-temperature adhesives of interest in the bonding of airframe components are investigated. A study of the effect of manufacturing variables such as adhesive type primer, on stress corrosion cracking susceptibility as a function of temperature is reported. Several commercial adhesives and one simple low-toughness adhesive are compared. Room-temperature fatigue or corrosion fatigue and room- temperature stress corrosion cracking resistant commercial high-toughness adhesives and simple systems are reported. This data indicates that crack growth in fatigue occurs in response to the number of cycles at a given applied crack extension force. (Author, modified-PL)
