Resumo: | In this work, composite materials based on polypropylene (PP) reinforced with alumina nanoparticles (Al2O3) and short carbon fibers (SCF), were developed, aiming at obtaining light materials, with high rigidity, mechanical resistance and thermal stability, capable of being processed in the machinery conventionally used in the polymer industry. For this purpose, polypropylene was processed with alumina, at levels defined through the response surface methodology inserted in the Minitab software, in order to evaluate the effect of incorporating alumina and polypropylene grafted with maleic anhydride (PP-g-MA) used as a compatibilizer agent in the samples. The composite that presented the best mechanical properties, in this case, the hybrid composite PP/PP-g-MA/Al2O3 was used as matrix. The new composites were prepared by filling this matrix with 6% wt. of alumina and variable contents of carbon fiber, between 10 wt% and 15 wt%. The tensile mechanical properties of the materials were evaluated according to standardized techniques. The materials obtained showed stiffness and mechanical strength superior to that presented by polypropylene. |

Com essa finalidade, polipropileno foi processado com alumina, em teores definidos através de metodologia de superfície de resposta inserida no software Minitab, de forma a se avaliar o efeito da incorporação de alumina e do polipropileno graftizado com anidrido maleico (PP-g-AM) usado como compatibilizante em algumas amostras. Os compósitos que apresentaram as melhores propriedades mecânicas, no caso, compósitos híbridos PP/PP-g-AM/Al2O3 foram usados como matriz e preparados utilizando teor de alumina de 6% m/m e teores de fibras de carbono variáveis, entre 10% m/m e 15% m/m. As propriedades dos materiais obtidos foram avaliadas através de diversas técnicas de caracterização como: ensaios mecânicos em tração, termogravimetria (TGA), calorimetria diferencial exploratória (DSC) e microscopia eletrônica de varredura (MEV). No presente artigo serão apresentados os resultados do ensaio mecânico em tração. Foi obtido nesse trabalho materiais à base de polipropileno com rigidez e resistência mecânica superiores as apresentadas pelo polipropileno.Universidade Federal de Viçosa - UFV2023-02-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArtigo, Manuscrito, Eventosapplication/pdfhttps://periodicos.ufv.br/jcec/article/view/1539110.18540/jcecvl9iss1pp15391-01eThe Journal of Engineering and Exact Sciences; Vol. 9 No. 1 (2023); 15391-01eThe Journal of Engineering and Exact Sciences; Vol. 9 Núm. 1 (2023); 15391-01eThe Journal of Engineering and Exact Sciences; v. 9 n. 1 (2023); 15391-01e2527-1075reponame:Revista de Engenharia Química e Químicainstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/jcec/article/view/15391/7812Copyright (c) 2023 The Journal of Engineering and Exact Scienceshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessFerreira, João Lucas Alexandre Nunes GalvãoRocha, Marisa Cristina Guimarães2023-02-24T19:29:16Zoai:ojs.periodicos.ufv.br:article/15391Revistahttp://www.seer.ufv.br/seer/rbeq2/index.php/req2/indexONGhttps://periodicos.ufv.br/jcec/oaijcec.journal@ufv.br||req2@ufv.br2446-94162446-9416opendoar:2023-02-24T19:29:16Revista de Engenharia Química e Química - Universidade Federal de Viçosa (UFV)false |
