Resumo: The effect of the distance between impact point and hole position and the angle of the hole with the vertical axis was studied. In order to understand this effect, flexural tests were also performed to evaluate the bending strength of CFRP. In terms of distance of the hole, a maximum reduction of 29.7% on the bending load for a distance of 0 mm was found. This reduction was 22.3% on the impact load. In terms of angle of the hole, a maximum load reduction of 15.6% on the bending strength was found and for the impact load this value was found to be 7% for 20º. The fatigue resistance was also studied. An average reduction of 68.5% on the fatigue resistance of GFRP was obtained for an impact energy of 12 J, in the presence of a hole.

Para avaliar este efeito, foram também realizados ensaios de flexão. Em termos de distância do furo, uma redução máxima da resistência à flexão de 29,7% foi verificada para uma distância do furo de 0 mm. Esta redução foi de 22,3% no carregamento de impacto. Em termos de ângulo do furo, a redução máxima do carregamento foi de 15,6% para a flexão e em relação ao impacto este valor foi de 7%, para um ângulo de 20º. A resistência à fadiga foi também estudada. Foi verificada uma redução média de 68,5% na resistência à fadiga em compósitos de fibra de vidro para uma energia de impacto de 12 J, na presença de um furo.Reis, Paulo Nobre Balbis dosGamboa, Pedro VieirauBibliorumSantos, Rafael Alexandre Mota dos2019-12-10T17:34:22Z2016-9-302016-11-042016-11-04T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfapplication/pdfhttp://hdl.handle.net/10400.6/7703TID:202330540enginfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2023-12-15T09:47:16Zoai:ubibliorum.ubi.pt:10400.6/7703Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-20T00:48:10.007921Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
