Resumo: The Sustainability has been evidence in the world today; organizations have sought to be more and more into this philosophy in their processes, whether products or attendance. In the present work were manufactured eco-composites with animal fiber (dog wool) that is currently discarded into the environment without any use. The fibers were characterized and made matting (non-woven). The phases of the project were consisted to develop methods and to convert these fibers (booster) blended with polyester resin (matrix) in different proportions (10%, 20% and 30%) at the composite. Were studied fiber characteristics, mechanical properties of the composites, water absorption and scanning electron microscopy. Initially, the fibers were treated with solution of sodium hydroxide of 0.05 mols, and then taken to matting preparing at the textile engineering laboratory - UFRN. The composites were made by compression molding, using an orthophthalic polyester resin as matrix and 1% MEK (methyl ethyl ketone peroxide) as initiator (catalyst). To evaluate the mechanical tests (tensile and flexural) and water absorption were made twelve specimens with dimensions 150x25x3 mm were cut randomly. According to the standard method, tensile tests (ASTM 3039) bending tests (ASTM D790) were performed at the mechanical testing of metals at laboratory UFRN. The results of these tests showed that the composite reinforced with 30% had a better behavior when exposed to tension charge; while on the three points bending test showed that the composite reinforced with 10% had a better behavior. In the water absorption test it was possible to see that the highest absorption happened on the composite reinforced with 30%. In the micrographs, it was possible to see the regions of rupture and behavior of the composite (booster / matrix)

No presente trabalho foram fabricados eco-compósitos com a fibra animal (lã canina) que atualmente é descartada no ambiente sem nenhum aproveitamento. As fibras foram caracterizadas e em seguida confeccionadas mantas (não tecidas). As fases do projeto consistiram em desenvolver métodos para converter estas fibras (reforço) misturadas com resina de poliéster (matriz) em distintas proporções (10%, 20% e 30%) nos compósitos. Foram estudadas as características da fibra, propriedades mecânicas dos compósitos, absorção de água e microscopia eletrônica de varredura. Inicialmente as fibras foram tratadas com uma solução de 0,05 mols de hidróxido de sódio, em seguida levadas a um preparador de mantas no Laboratório de Engenharia Têxtil da UFRN. Os compósitos foram fabricados em molde por compressão, utilizando a resina de poliéster ortoftálico como matriz e 1% de peróxido MEK (peróxido de metil etil cetona) como iniciador (catalizador). Para avaliação dos ensaios mecânicos (tração e flexão) e absorção d agua, foram confeccionados corpos de prova com as dimensões 150x25x3 mm. De acordo com as normas, os ensaios de tração (ASTM 3039) e flexão em três pontos (ASTM D790) foram realizados no Laboratório de metais e ensaios mecânicos da UFRN. Analisando os resultados destes ensaios, observou-se que o compósito reforçado com 30% apresentou um melhor comportamento quando expostos a carregamentos de tração, enquanto que no teste de flexão observou-se que o compósito reforçado com 10% apresentou um melhor comportamento. No ensaio de absorção d agua foi possível observar um equilíbrio na absorção de umidade dos compósitos sendo seu maior percentual de absorção no compósito de 30%. Nas micrografias, se observa as regiões de ruptura do compósito e seu comportamento (fibra/matriz)application/pdfporUniversidade Federal do Rio Grande do NortePrograma de Pós-Graduação em Engenharia MecânicaUFRNBRTecnologia de Materiais; Projetos Mecânicos; TermociênciasFibras têxteisEco-compósitosLã caninatextiles fiberseco-compositesdog woolCNPQ::ENGENHARIAS::ENGENHARIA MECANICAFabricação de eco-composito com a fibra de lã caninainfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFRNinstname:Universidade Federal do Rio Grande do Norte (UFRN)instacron:UFRNORIGINALFranciscoCS_DISSERT.pdfapplication/pdf2144999https://repositorio.ufrn.br/bitstream/123456789/15690/1/FranciscoCS_DISSERT.pdf11a0f7255d18cc7bb37fb7499b866d52MD51TEXTFranciscoCS_DISSERT.pdf.txtFranciscoCS_DISSERT.pdf.txtExtracted texttext/plain81652https://repositorio.ufrn.br/bitstream/123456789/15690/6/FranciscoCS_DISSERT.pdf.txtcd4ead4ffab25cdc6bf6d1757c1d9c50MD56THUMBNAILFranciscoCS_DISSERT.pdf.jpgFranciscoCS_DISSERT.pdf.jpgIM Thumbnailimage/jpeg2641https://repositorio.ufrn.br/bitstream/123456789/15690/7/FranciscoCS_DISSERT.pdf.jpgcc50a519a8e2f9ab74642534bac83548MD57123456789/156902017-11-02 00:03:19.612oai:https://repositorio.ufrn.br:123456789/15690Repositório de PublicaçõesPUBhttp://repositorio.ufrn.br/oai/opendoar:2017-11-02T03:03:19Repositório Institucional da UFRN - Universidade Federal do Rio Grande do Norte (UFRN)false
