The effects of such repair methods on the structural integrity, however, are still largely unknown. In this paper, the mechanical property restoration, failure mechanism, and influence of fiber orientation mismatch between parent and repair materials of 1:50 scarf joints are studied on monolithic glass fiber-reinforced polymer (GFRP) specimens under tensile load. Two different parent orientations of [\u221245\/+45]2S and [0\/90]2S are exemplarily examined, and control specimens are taken as a baseline for the tensile strength and stiffness property recovery assessment. Using a layer-wise stress analysis with finite element simulations conducted with ANSYS Composite PrepPost to support the experimental investigation, the fiber orientation with respect to load direction is shown to affect the critical regions and thereby failure mechanism of the scarf joint specimens.<\/jats:p>","DOI":"10.3390\/ma14071806","type":"journal-article","created":{"date-parts":[[2021,4,6]],"date-time":"2021-04-06T10:34:12Z","timestamp":1617705252000},"page":"1806","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Failure Mechanisms of GFRP Scarf Joints under Tensile Load"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2956-3272","authenticated-orcid":false,"given":"Carineh","family":"Ghafafian","sequence":"first","affiliation":[{"name":"Federal Institute for Materials Research and Testing (BAM), Unter den Eichen 87, 12205 Berlin, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4421-2465","authenticated-orcid":false,"given":"Bartosz","family":"Popiela","sequence":"additional","affiliation":[{"name":"Federal Institute for Materials Research and Testing (BAM), Unter den Eichen 87, 12205 Berlin, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7993-9082","authenticated-orcid":false,"given":"Volker","family":"Trappe","sequence":"additional","affiliation":[{"name":"Federal Institute for Materials Research and Testing (BAM), Unter den Eichen 87, 12205 Berlin, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,4,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"94","DOI":"10.1016\/j.ijfatigue.2009.02.003","article-title":"Lifetime Assessment for GFRP-Gliders Using a Representative Substructure","volume":"32","author":"Grasse","year":"2010","journal-title":"Int.
