“…A utilização de fibras vegetais para a preparação de compósitos poliméricos tem sido bastante explorada em pesquisas científicas e também na área industrial, sobretudo automobilística, devido à possibilidade de gerar materiais com custos reduzidos e propriedades suficientes para garantir sua aplicação em diversas situações [18,19]. Somando-se a isto, no Brasil há uma grande disponibilidade de fibras vegetais que podem ser utilizadas para a preparação de compósitos poliméricos, como é o caso do bagaço de cana [10].…”

A utilização de polímeros termoplásticos reciclados a partir de embalagens para a preparação de compósitos com fibras vegetais é uma alternativa tecnológica de grande potencial que pode conciliar viabilidade econô-mica com benefícios ambientais. No Brasil, muitos estudos têm sido feitos para a utilização de fibras vegetais em compósitos com matriz polimérica devido à grande disponibilidade de resíduos desses materiais. O País também merece destaque pelo alto índice de reciclagem mecânica de polímeros termoplásticos, principalmente do polímero poli(tereftalato de etileno) (PET). O presente trabalho teve como objetivo a preparação de compósitos por processamento termomecânico a partir de fibra de cana-de-açúcar tratada por explosão a vapor com matriz polimérica de PET e a avaliação do comportamento das propriedades do material em comparação aos compósitos com fibras não tratadas. Apesar das mudanças significativas na morfologia das fibras de cana-de-açúcar com o tratamento por explosão a vapor, não houve diferenças significativas nas propriedades dos compósitos PET/fibra tratada com relação aos compósitos PET/fibra in natura devido à não penetração da matriz polimérica no interior da estrutura da fibra modificada com o tratamento. O uso de outros tipos de matrizes poliméricas recicladas e adaptações nas operações de processamento dos materiais são alternativas que podem ainda potencializar o uso de fibra de cana-de-açúcar tratada por explosão a vapor na preparação de compósitos poliméricos e contribuir para a produção de materiais ambientalmente sustentáveis. Palavras-chave:Compósitos poliméricos, fibra de cana-de-açúcar, PET, explosão a vapor. ABSTRACTThe use of recycled thermoplastic polymers from packaging and natural fibers for preparation of polymeric composites is a technological alternative of high potential to conciliate economic viability with environmental benefits. In Brazil, several studies have been performed aiming the use of natural fibers in polymeric composites due to the high availability of the agricultural waste. The high index of mechanical recycling of thermoplastic polymers, mainly of the polymer polyethylene terephthalate (PET), also worth mentioning in the Country. This study aimed the preparation of PET/sugarcane fiber composites by thermomechanical processing after treating of the fibers by steam explosion and the evaluation of the composites properties when compared with composites using fibers without treatment. Although of the significant changes in the fiber morphology with steam explosion treatment, there were not significant difference between properties of the composites with treated fibers and the composites with not treated fibers due to the insufficient penetration of the polymeric matrix into structure of the modified fiber after treatment. The use of others recycled polymeric matrix as well as adjustments in the operations for materials processing are alternatives that can improve the use of sugarcane fiber treated by steam explosion in the preparation of polymeric composites...

Fiber-matrix interaction at the interphase is one very important property that is of great concern to all polymer scientists involved in polymer composites. Many of the failures can be traced to the type of interfacial interaction existing in the composites. That is why highlighting the factors that dictate the type of and the extent of interactions at the interphases become very necessary. Natural fiber polymer composites have found application in many fields of human endeavors. To continue this growth being experienced, the factors that determine the formation of good interaction at the interphase most be understood, so that they can be manipulated for a better result.

Natural fiber composites are designed for different purposes including structural and non-structural ones. These natural fiber composites vary greatly in their properties including mechanical properties. Mechanical properties which include the tensile and flexural properties are highly dependent on factors such as matrix type, filler type, processing, post processing treatment and many more, factors which are quite application specific. However, many research works develop their natural fiber composite before considering the possible applications. This chapter intends to X-ray the factors that affect the mechanical properties as it relates to structural and biomedical applications and suggest ways of improving the mechanical properties.
