Abstract
A method for repeatably fabricating a test specimen assembly comprising a pair of fiber-reinforced plastic (FRP) test specimens adhesively bonded together, the bonded joint having respective areas of substantially different, but consistent variable adhesive bond strengths suitable as a calibration standard. The method comprises fabricating a first FRP test specimen having a bonding surface with first and second areas that have substantially different bonded joint performance-governing characteristics and then using adhesive to bond the bonding surface of the first FRP test specimen to the bonding surface of a second FRP test specimen. The different bonded joint performance-governing characteristics are achieved by treating first and second areas of the surface of the first FRP test specimen using different respective surface preparation techniques.
