Resumo: The aim of this study is to test and compare the flexural strength of milled polymer bars, with and without glass fiber reinforcement. The number of samples in the study was defined through a pilot study on a universal testing machine (EMIC) (n = 5). The brands analyzed in this study were Arch Free Metal, Zantex, Bioplas and PEEK. All samples were submitted to thermal aging before the three-point flexural test. Fracture patterns were analyzed using a Scanning Electron Microscope. Results show that the Arch Free Metal bar presented the largest flexural strength, followed by Zantex and PEEK bars, that lacked statistical difference, and Bioplas bars. Regarding fracture patterns, Arch Free Metal and Zantex bars were partially fractured and showed partial glass fiber rupture; PEEK bars were not fractured and showed plastic behavior; and Bioplas bars were fractured. It is possible to conclude that the reinforced polymer bar Arch Free Metal has a better performance in terms of flexural strength than the other tested materials.

Para establecer el número de muestra se realizó un estudio piloto en la máquina universal de ensayos (EMIC), definiendo n=5. Las marcas probadas fueron Arch Free Metal, Zantex, Bioplas y PEEK Polymers. Todas las muestras fueron sometidas a un envejecimiento térmico previo y al ensayo de flexión en tres puntos. Los patrones de fractura se analizaron en el microscopio electrónico de barrido. Los resultados mostraron que la barra Arch Free Metal obtuvo valores de resistencia a la flexión significativamente superiores a los encontrados en las barras Zantex y PEEK, las cuales obtuvieron resultados similares entre sí y estas a su vez mostraron resistencia estadísticamente mayor que la barra fabricada en Bioplas. En cuanto a los patrones de fractura, las barras metálicas Arch Free y Zantex presentaron fractura y ruptura parcial de las fibras de vidrio, mientras que las barras de PEEK no alcanzaron la fractura y mostraron un comportamiento plástico, mientras que las de Bioplas se fracturaron. Se concluye que la barra polimérica reforzada Arch Free Metal puede tener un mejor desempeño que las barras fabricadas con otros materiales en cuanto a resistencia a la flexión.O objetivo desta pesquisa foi testar e comparar a resistência a flexão de barras poliméricas fresadas, reforçadas ou não com fibras de vidro. Para estabelecer o número amostral realizou-se um estudo piloto na máquina de ensaios universais (EMIC), definindo n=5. As marcas testadas foram os polímeros Arch Free Metal, Zantex, Bioplas e PEEK. Todas as amostras foram submetidas a um envelhecimento térmico prévio e ao teste de flexão a três pontos. Foram analisados os padrões de fratura no microscópio eletrônico de varredura. Os resultados mostraram que a barra em Arch Free Metal obteve valores de resistência a flexão significativamente superiores aos encontrados nas barras de Zantex e PEEK, que obtiveram resultados semelhantes entre si e estas, por sua vez, mostraram resistência estatisticamente maior que a barra confeccionada em Bioplas. Quanto aos padrões de fratura, as barras de Arch Free metal e de Zantex apresentaram fratura e rompimento parcial das fibras de vidro, enquanto as de PEEK não chegaram à fratura e demostraram um comportamento plástico, já as de Bioplas fraturaram. Conclui-se que a barra polimérica reforçada de Arch Free Metal pode apresentar melhor desempenho que barras confeccionadas com os demais materiais no que diz respeito à resistência à flexão. Research, Society and Development2022-05-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/2962610.33448/rsd-v11i7.29626Research, Society and Development; Vol. 11 No. 7; e2711729626Research, Society and Development; Vol. 11 Núm. 7; e2711729626Research, Society and Development; v. 11 n. 7; e27117296262525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/29626/25589Copyright (c) 2022 Roberto Burguer Neto; Amanda Gonçalves Franco; Geraldo Alberto Pinheiro de Carvalho; Caio Marques Martins; Silvio Mecca Junior; Fabiano Perez; Elimario Venturin Ramos; Sérgio Candido Dias; Aline Batista Gonçalves Francohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessBurguer Neto, RobertoFranco, Amanda Gonçalves Carvalho, Geraldo Alberto Pinheiro de Martins, Caio Marques Mecca Junior, SilvioPerez, FabianoRamos, Elimario Venturin Dias, Sérgio Candido Franco, Aline Batista Gonçalves 2022-06-06T15:12:05Zoai:ojs.pkp.sfu.ca:article/29626Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:46:39.087659Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
