There is a need to define drying procedures which guarantee the quality of the bonded joint. An experimental investigation has been carried out on the effect of pre-bond moisture on the fracture toughness (GIC) and failure behavior of repair joints bonded with adhesive films. Substrates were conditioned by immersion in distilled water at 70 C for 336 h and subsequently dried for 1 h or 24 h to achieve different moisture contents before bonding. Specimens of bonded joints were tested under mode I loading at room temperature. The fracture toughness (GIC) decreased with increasing pre-bond moisture level in the substrates. Fractographic inspection revealed an enhancement of the cohesive mode of failure as the pre-bond moisture decreased. Extending the duration of the drying operation of the substrate with pre-bond moisture, caused an improvement in the fracture toughness of the joint, although not a full recovery of the reference values obtained in absence of pre-bond moisture" , "dc.description.sponsorship": "This work has been partially supported by an AIRBUS contract, and by the Spanish Ministerio de Economia y Competitividad through the grant MAT2012-37552-C03-03" , "dc.format.mimetype": "application/pdf" , "dc.language.iso": "eng" , "dc.publisher": "Elsevier" , "dc.relation": "MINECO/PN 2013-2015/MAT2012-37552-C03-03" , "dc.relation.isformatof": "Reproducció digital del document publicat a: http://dx.doi.org/10.1016/j.ijadhadh.2013.12.007" , "dc.relation.ispartof": "© International Journal of Adhesion and Adhesives, 2014, vol. 49, p. 80-89" , "dc.relation.ispartofseries": "Articles publicats (D-EMCI)" , "dc.rights": "Tots els drets reservats" , "dc.subject": "Resistència de materials" , "dc.subject": "Strength of materials" , "dc.subject": "Mecànica de fractura" , "dc.subject": "Fracture mechanics" , "dc.subject": "Assaigs de materials" , "dc.subject": "Materials -- Testing" , "dc.subject": "Lligants (Materials)" , "dc.subject": "Binders (Materials)" , "dc.title": "Influence of pre-bond moisture in the adherents on the fracture toughness of bonded joints for composite repairs" , "dc.type": "info:eu-repo/semantics/article" , "dc.rights.accessRights": "info:eu-repo/semantics/embargoedAccess" , "dc.embargo.terms": "Cap" , "dc.type.version": "info:eu-repo/semantics/publishedVersion" , "dc.identifier.doi": "http://dx.doi.org/10.1016/j.ijadhadh.2013.12.007" , "dc.identifier.idgrec": "019170" , "dc.contributor.funder": "Ministerio de Economía y Competitividad (Espanya)" }
