Institution National Aerospace Laboratory NLR Date 1978-12-31 Abstract Fracture toughness measurements were carried out to test the ageing behaviour of three adhesives in different environments. It was possible to compare and evaluate adhesives and surface pretreatments. It is doubtful whether the derived R-curves could be used for residual strength calculations in certain environments. Phosphoric acid anodizing resulted in different durabilities for the adhesives. For a rate sensitive adhesive high displacement rates resulted in large crack extensions and high cracking rates. Compilation of the test data is given in NLR TR 78020 U.
