Resumo: | In this work was evaluated the mechanical properties and thickness of swelling in wood plastic composite made by extrusion using Pinus caribaea sawdust and three types of recycled thermoplastics (PET, LDPE, PP). Four formulations with different proportions of thermoplastics combined or not were assessed. The mechanical parameters evaluated were static bending, longitudinal compression and perpendicular traction parallel to the faces, to evaluate the thickness of swelling the boards were submersed in water at ambient temperature (25 °C) and analyzed in intervals during 1500 hours. The results indicated that there is a tendency to reduce the thickness of swelling in treatment four in relation the other treatments. The mixing of the thermoplastics in this treatment caused a decrease in water absorption improving this physical property of swelling. This treatment showed better mechanical properties. It is important to note that treatment 3 showed similar mechanical properties, and good response in relation to swelling. |

Foram avaliadas quatro formulações com diferentes proporções de termoplásticos combinados ou não. Os parâmetros mecânicos avaliados foram flexão estática, compressão longitudinal e tração paralela às faces. Para avaliar o inchamento em espessura os painéis foram submersos em água à temperatura ambiente (25 °C) e analisados em intervalos durante 1500 horas. Os resultados indicaram que há uma tendência a reduzir a espessura do inchamento no tratamento quatro em relação aos demais tratamentos. A mistura dos termoplásticos neste tratamento causou uma diminuição na absorção de água, melhorando esta propriedade física do inchamento. Este tratamento mostrou melhores propriedades mecânicas. É importante notar que o tratamento 3 mostrou propriedades mecânicas semelhantes e boa resposta em relação ao inchamento.CERNECERNE2019-02-19info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://cerne.ufla.br/site/index.php/CERNE/article/view/1948CERNE; Vol. 24 No. 4 (2018); 369-378CERNE; v. 24 n. 4 (2018); 369-3782317-63420104-7760reponame:Cerne (Online)instname:Universidade Federal de Lavras (UFLA)instacron:UFLAenghttps://cerne.ufla.br/site/index.php/CERNE/article/view/1948/1099Copyright (c) 2019 CERNEinfo:eu-repo/semantics/openAccessLopez, Yonny MartinezPaes, Juarez BenignoRodríguez, Emilio MartínezGustave, DonatianGonçalves, Fabricio Gomes2019-06-05T14:09:33Zoai:cerne.ufla.br:article/1948Revistahttps://cerne.ufla.br/site/index.php/CERNEPUBhttps://cerne.ufla.br/site/index.php/CERNE/oaicerne@dcf.ufla.br||cerne@dcf.ufla.br2317-63420104-7760opendoar:2024-05-21T19:54:38.595596Cerne (Online) - Universidade Federal de Lavras (UFLA)true |
