Abstract. The use of natural fibres in high performance composite requires an accurate understanding of the mechanical behaviour of the fibres themselves. As for all biobased materials, the mechanical properties of natural fibres depend generally on the testing rate and on the environmental conditions. In addition, natural fibres as hemp for example exhibit a particular mechanism of stiffness increase and accommodation phenomena under cyclic loading. Loading rate, temperature and humidity effects on the viscoelastic properties of hemp fibres were investigated in this work. The collected results clearly emphasis the involvement of time-dependant and mechano-sorptive mechanisms.

“…Em busca de uma solução para esse problema, várias pesquisas e trabalhos na área de compósitos poliméricos foram e estão sendo realizados para garantir à preservação ambiental e proporcionar um melhor padrão de vida a sociedade como um todo. Dentre as pesquisas nesta área, que vêem crescendo e que aparecem em destaque, são as que buscam a aplicação para modificadores naturais, principalmente quanto à utilização de fibras naturais [5][6][7] . As fibras naturais são aquelas encontradas na natureza e utilizadas "in natura" ou após beneficiamento.…”

“…Destaque deve ser dado à utilização de fibras naturais de origem vegetal, em razão da enorme variedade de plantas disponíveis na biodiversidade, passíveis de serem pesquisadas, e por ser uma fonte de recurso renovável. Diversas fibras naturais vegetais são produzidas em praticamente todos os países e usualmente são designadas por materiais lignocelulósicos [6] . No Brasil, existe uma grande variedade de fibras vegetais com diferentes propriedades químicas, físicas e mecânicas.…”

Resumo: Este artigo tem a intenção de divulgar e apresentar a inserção da área ou da cadeia produtiva de Compósitos Poliméricos com Fibras Vegetais Naturais dentro do contexto do Projeto Fênix Amazônico. Duas frentes de pesquisa e desenvolvimento na área de compósitos de polímeros com fibras naturais vegetais são propostas: uma que trabalharia com sistemas de produção com maquinário relativamente barato e simples, para que as comunidades rurais da Amazônia pudessem absorver tal tecnologia; uma outra frente para desenvolver materiais compósitos com tecnologia de fabricação mais avançada. Deste modo esperamos despertar o interesse da comunidade científica e tecnológica das mais diversas áreas em colaborar com o desenvolvimento de novas tecnologias que possam ser utilizadas para a recuperação de áreas degradadas da Amazônia. Palavras-chave: Compósitos poliméricos, fibras vegetais naturais, termoplástico/madeira, biodiversidade, Floresta Amazônica, parceria. Development of Polymeric Composites with Natural Fibers: A Contribution to the Sustainability of AmazonAbstract: This paper presents the research on Polymeric Composites with Natural Fibers in the Amazon Fenix Project. Two research and development fields based on polymeric composites with natural vegetable fibers are proposed: the first one considers production systems with simple, cheap machinery to facilitate technology assimilation by rural communities in the Amazon; the second one aims at developing composite materials with advanced production technology. It is hoped to raise awareness for scientific and technological development for the recovery of degraded areas in Amazon.

“…Osorio et al [12] and Nechwatal et al [24] reported that the clamping length has an inversely proportional relationship to the strength of the fibre due to the increase in the existing defects that weaken the fibre. The reason behind the inverse relation between the fibre length and its mechanical strength was clearly explained by Defoirdt et al [15].…”

Natural fibres have excited growing attention in the last decade since they offer the potential to act as candidates substituting for man-made fibres as composite reinforcements. Their superiority over synthetic fibres is that they are environmentally friendly and biodegradable. Numerous industrial sectors are interested in such composites, including but to name a few the aeronautical and the automotive fields. However natural fibres tend to suffer from large variability in properties compared to the "traditional" man-made fibres, and the performance of their composites often does not conform to that theoretically predicted from single-fibre tests. This study investigates the properties of the single fibres. The mechanical properties of the fibres were correlated to their microstructure. There are factors that were found to contribute to the reported variability, some of which are inherent in the fibres and some are related to testing parameters.
