Natural fibers today are a popular choice for applications in composite manufacturing.Based on the sustainability benefits, biofibers such as plant fibers are replacing synthetic fibers in composites. These fibers are used to manufacture several biocomposites. The chemical composition and properties of each of the fibers changes, which demands the detailed comparison of these fibers. The reinforcement potential of natural fibers and their properties have been described in numerous papers. Today, high performance biocomposites are produced from several years of research. Plant fibers, particularly bast and leaf, find applications in automotive industries. While most of the other fibers are explored in lab scales they have not yet found large-scale commercial applications. It is necessary to also consider other fibers such as ones made from seed (coir) and animals (chicken feather) as they are secondary or made from waste products. Few plant fibers such as bast fibers are often reviewed briefly but other plant and animal fibers are not discussed in detail. This review paper discusses all the six types of plant fibers such as bast, leaf, seed, straw, grass, and wood, together with animal fibers and regenerated cellulose fibers. Additionally, the review considers developments dealing with natural fibers and their composites. The fiber source, extraction, availability, type, composition, and mechanical properties are discussed. The advantages and disadvantages of using each biofiber are discussed. Three fabric architectures such as nonwoven, woven and knitted have been briefly discussed. Finally, the paper presents the overview of the results from the composites made from each fiber with suitable references for in-depth studies.

“…Então se iniciou com o traço de 1:1:0,40 (cimento: areia: relação água/cimento em massa), porém, ao se adicionar as fibras às argamassas, a mistura tornou-se pouco trabalhá-vel, chegando então ao valor de 0,59 para a relação água cimento. Então foram moldados corpos de prova prismáticos, de dimensões 50 x 50 x 300 mm 3 , dos compósitos reforçados com fibra (CRF) com diferentes frações volumétricas e comprimentos de fibras, sendo eles identificados por 2%CRF25, 3%CRF25, 2%CRF45 e 3%CRF45, em que 2% e 3% indicam suas frações volumétricas e 25 e 45 indicam os comprimentos de fibras (25 mm e 45 mm). Os corpos de provas de argamassa de referência foram denominados por AR.…”

“…As fibras vegetais naturais parecem oferecer uma grande oportunidade a esse respeito, dentre essas fibras destaca-se a fibra do curauá, obtida por meio da extração das folhas da Ananas erectifolius, que normalmente é chamada de curauá [3], cujo seu cultivo é feito principalmente na região amazônica. Sua produção no Brasil no ano de 2003 chegou a 150 toneladas [7] e isso vem aumentando com os anos.…”

RESUMOO desenvolvimento e comercialização de materiais compósitos produzidos a partir de fibras naturais são considerados extremamente importante, uma vez que essas fibras reduzirão a dependência dos materiais produzidos com recursos não renováveis. Dentre essas fibras naturais destaca-se a fibra do curauá, sua utilização na produção de compósitos melhora de forma notável as propriedades do conjunto fibra matriz, logo o presente artigo objetiva estudar as propriedades mecânicas de compósitos reforçados com fibra de curauá, em especial sua resistência à flexão e tenacidade. Para isso foram confeccionadas cinco famílias de argamassas, uma de referência sem utilização da fibra e as outras quatro reforçada com fibra variando o comprimento da fibra e sua fração volumétrica. Verificou-se que a fibra do curauá ao ser adicionada em matriz cimentícia melhora suas propriedades mecânicas comparada a um compósito não reforçado com fibra, sua deformação, resistên-cia à flexão e tenacidade são melhoradas.Palavras-chave: comportamento mecânico, fibras naturais, materiais não convencionais, compósitos cimentícios, fibra de curauá. ABSTRACTThe composites material produced from natural fibers development and commercialization are considered extremely important because these fibers will reduce the material produced with non-renewable resources dependence. Among these fibers, there is the Curauá fiber, its use in composites production improves the ensemble matrice fiber properties, then this article aims to study the composites reinforced with Curauá fibers mechanical properties, especially its bending resistance and toughness. For achieve those objectives, it was produced five mortar groups, one for reference, without the fiber utilization, and another four groups with fiber reinforcement varying the fiber length and its volume fraction. It was noted that Curauá fiber, when added to cement matrice, improves its mechanical properties compared to a composite without the fiber reinforcement, its deflection, bending resistance and toughness are improved.
