“…An example is the relatively unknown fiber extracted from the leaves of an Andean plant ( Furcraea andina ). This fique fiber has been brought to attention for its potential as a composite reinforcement [34,35,36,37,38,39]. Figure 1 illustrates: (a) fique plantation in Colombia and (b) a bundle of fique fibers extracted from the leaves of the plant.…”

“…The extraction cost, from plantation to clean fibers (see Figure 1a,b), is around US$0.14, while the consumer price varies from US$0.36 to US$0.45. Fiber surface modification [34] and thermal degradation [35] as well as bending [36] and tensile [37,38] properties of fique fiber-reinforced composites were preliminarily investigated. Moreover, an inverse correlation between the density and the diameter of fique fibers was established [39].…”

Abstract:A relatively unknown natural fiber extracted from the leaves of the fique plant, native of the South American Andes, has recently shown potential as reinforcement of polymer composites for engineering applications. Preliminary investigations indicated a promising substitute for synthetic fibers, competing with other well-known natural fibers. The fabric made from fique fibers have not yet been investigated as possible composite reinforcement. Therefore, in the present work a more thorough characterization of fique fabric as a reinforcement of composites with a polyester matrix was performed. Thermal mechanical properties of fique fabric composites were determined by dynamic mechanical analysis (DMA). The ballistic performance of plain woven fique fabric-reinforced polyester matrix composites was investigated as a second layer in a multilayered armor system (MAS). The results revealed a sensible improvement in thermal dynamic mechanical behavior. Both viscoelastic stiffness and glass transition temperature were increased with the amount of incorporated fique fabric. In terms of ballistic results, the fique fabric composites present a performance similar to that of the much stronger Kevlar TM as an MAS second layer with the same thickness. A cost analysis indicated that armor vests with fique fabric composites as an MAS second layer would be 13 times less expensive than a similar creation made with Kevlar™.

“…b Facultad de Ingeniería, Universidad de Antioquia, Medellin, Colombia. Considering the superior properties of fique fiber, such as strength and stifness, when compared with other common natural fibers, this fiber have been brought to attention as potential reinforcement for composites, either in the form of filament [28][29][30][31][32][33] or even in the form of fabric [34][35] . In particular the thermal and mechanical properties, important for engineering applications involving change in temperature conditions, were recently studied for fique fabric polyester composites by dynamic mechanical analysis (DMA) 34 .…”

The fique is a plant typical of the Colombian Andes, from which relatively common items are fabricated. One of these is woven fabric extensively applied in sackcloths. The mechanical strength of fique fabric have motivated recent investigations on possible reinforcement of polymer matrix composites. For this purpose its thermo-mechanical behavior was unveiled. In particular, dynamic mechanical analysis (DMA) of fique fabric reinforced polyester matrix composites disclosed improved viscoelastic behavior in association with change in the glass transition temperature. The present work extends this investigation to epoxy matrix, which is one of the most employed thermoset polymer for composite matrix. Fique fabric volumetric fractions of up to 50% are for the first time incorporated into epoxy composites. It was found that these incorporations significantly increased the viscoelastic stiffness of the composite, given by the storage modulus (E'), in the temperature interval from -50 to 170°C. An accentuated softening in viscoelastic stiffness was revealed for all composites above 75°C. Peaks in both the loss modulus (E") and tangent delta (tan δ), respectively associated with the lower and upper limits of the glass transition temperature, were shifted towards higher temperatures with increasing amount of fique fabric.

“…Para o conhecimento dos autores do presente trabalho, Wambua et al [7] foram provavelmente o primeiro grupo a realizar uma investigação sistemática sobre as propriedades balísticas dos compósitos reforçados com fibras lignocelulósicas. Publicações recentes [13][14][15][16][17] revelaram que as fibras naturais, assim como os compósitos de polímeros reforçados com tecidos, exibem desempenho balístico comparável ao Kevlar TM . O crescente interesse por aplicações de engenharia está continuamente exigindo trabalhos de pesquisa sobre fibras e tecidos naturais promissores menos comuns.…”

“…O crescente interesse por aplicações de engenharia está continuamente exigindo trabalhos de pesquisa sobre fibras e tecidos naturais promissores menos comuns. Um exemplo é a fibra de fique que chamou a atenção por seu potencial como um reforço em compósitos [13][14][15][16][17].Uma forma de avaliar a eficácia de um sistema de blindagem balística é baseada em medidas de velocidade em que um projétil específico atinge a blindagem.Neste trabalho, avaliou-se os materiais por meio da medida da energia absorvida do projétil [8,9], permitindo análise individual de materiais diferentes. Dessa forma, o objetivo deste trabalho foi avaliar o desempenho individual de compósitos de matriz epóxi reforçados com 15, 30, 40 e 50% vol.…”

Resumo O desenvolvimento de materiais compósitos de matriz polimérica (CMPs) reforçados com fibras naturais se alia à ideia sustentabilidade e potencializa a produção de materiais ambientalmente corretos. Em aplicações estruturais, quando é fundamental para o projeto uma elevada relação resistência peso, os CMPs vêm substituindo com sucesso diversos materiais convencionais.Atualmente, tecidos de fibras sintéticas possuem preferência para a camada intermediária em sistemas de blindagem multicamadas (SBM). Todavia, compósitos reforçados com fibras de fique têm sido estudados como segunda camada nos SBMmotivado pela sua baixa densidade e baixo custo. No presente trabalho foi estudado o comportamento balístico de compósitos epóxidicos fabricados com tecido de fique submetidos ao impacto com munição 7,62 mm. De tal modo que compósitos com 15, 30, 40 e 50%vol. de tecido foram produzidos e testados como sistema independente para avaliar a energia absorvida pela blindagem, comparando os resultados com amostras de laminados de Kevlar TM , utilizando a distribuição de Weibull para análise estatística. Entre os materiais testados, os compósitos com 50% de tecido foram considerados a melhor alternativa de substituição ao Kevlar TM. Palavras-chave:Tecido de fique; Blindagem balística; Fibras naturais; Compósitos.
