• Description:
  The long-term effects of surface preparation techniques for composite bonded joints are addressed. Several potential factors are evaluated, concentrating on the effects of peel plies and grit blasting on the fracture toughness and failure mode of adhesively bonded composites. An evaluation of the floating roller peel test configuration is described, where the intent was to extract quantitative data from this commonly used quality control test method. Subsequently, an alternate form of the double cantilever beam (DCB) test was developed and used for a sequence of test evaluations. The research will aid the interpretation of a form of the wedge test where the usual aluminum adherends are replaced by composite adherends.
