Abstract in Portuguese
Com o reconhecimento dos aspectos ambientais envolvidos nos processos de produção e consumo, estes passaram a ganhar cada vez mais notoriedade, o que gerou intensas discussões e realizações de conferências e estudos sobre o meio ambiente no mundo todo, provocando o surgimento dos termos: eco desenvolvimento e desenvolvimento sustentável A partir deste momento, a adequação dos processos produtivos e o uso de materiais ecologicamente corretos ou ecologicamente amigáveis (Eco-friendly) e/ou oriundos de fontes renováveis, tornaram-se alvos de diversos estudos, estando os, eco compósitos reforçados por fibras vegetais, entre os materiais de estudo de maior relevância. Assim, este estudo se propôs o desenvolvimento de um eco compósito sanduíche polimérico reforçado por fibras vegetais, para aplicação em materiais e equipamentos esportivos, sendo importante do ponto de vista econômico e social quando, que pode representar uma alternativa de geração de renda a comunidades tradicionais e agregando valor as fibras naturais produzidas na região amazônica. Para isso, realizou estudos de absorção de energia mecânica e caracterização mecânica do miriti (Mauritia flexuosa L. f), material que após processo de obtenção do miriti laminado colado (CLM), compões o núcleo do Eco Compósito. Os painéis CLM também foram caracterizados mecanicamente por ensaios de flexão e cisalhamento. Os resultados foram comparados a resultados teóricos. Posteriormente, foram produzidos eco compósitos sanduíche, com faces de poliuretano de mamona, reforçadas por fibras de juta, com núcleo de CLM. Esses compósitos foram caracterizados mecanicamente por flexão e comparados a resultados teóricos obtidos. O material desenvolvido apresentou resultados promissores do ponto de vista mecânico e sustentável.

Abstract in English
With the recognition of the environmental aspects involved in the production and consumption processes, these began to gain more and more notoriety, which generated intense discussions and conferences and studies on the environment around the world, causing the emergence of the terms: eco development and sustainable development From this moment on, the adequacy of production processes and the use of ecologically correct or ecologically friendly materials (Eco-friendly) and/or from renewable sources have become targets of several studies, with ecocomposites reinforced by fibers vegetables, among the most relevant study materials. Thus, this study proposed the development of an eco-composite polymeric sandwich reinforced by vegetable fibers, for application in sports materials and equipment, being important from an economic and social point of view, as it can represent an alternative for generating income for traditional communities and adding value to natural fibers produced in the Amazon region. To this end, it carried out mechanical energy absorption studies and mechanical characterization of miriti (Mauritia flexuosa L. f), a material that, after the process of obtaining glued laminated miriti (CLM), makes up the core of the Eco Composite. The CLM panels were also mechanically characterized by bending and shear tests. The results were compared to theoretical results. Subsequently, eco-composite sandwiches were produced, with castor polyurethane faces reinforced by jute fibers, with a CLM core. These composites were mechanically characterized by bending and compared to theoretical results obtained. The material developed showed promising results from a mechanical and sustainable point of view.
