“…Brazil is the one country to produce curaua fibers for commercial purposes; it produced around 150 tons in the year 2003. 157 The curaua plant leaves are hard and erect with flat surfaces and required minimum of 2000 mm of precipitation annually. The plant produces about 50-60 leaves annually and the leaves grow to about 1.5 m in eight months period while the dry fiber content is only about 5-8%.…”

“…The plant produces about 50-60 leaves annually and the leaves grow to about 1.5 m in eight months period while the dry fiber content is only about 5-8%. 157 The plant lifetime is about five years and each plant produces up to seven scions a year. 158 This fiber is often replaced by sisal fiber due to low production/cultivation of curaua and a higher demand for natural fibers.…”

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.

“…1. In 2003, Brazil produced 150 ton of curaua (Leão, Sartor, & Carashi, 2006). Previous studies indicate that curaua fibre is a promising material to reinforce thermosets and thermoplastics (Leão, Rowell, & Tavares, 1998;Santos, Spinacé, Fermoselli, & De Paoli, 2007), however, its surface treatment may improve this effect and was not studied.…”

“…Review papers [1][2][3][4][5][6][7][8][9][10][11][12][13] and possible uses as engineering materials reinforcing higher aggregate value polymer composites, have totally ignored the malva fiber. As an exception, Leão et al 21 indicate the malva fiber composites as an alternative for the automotive industry. Our recent investigations, however, disclosed its potential as composite reinforcement.…”

Flexural Behavior of Epoxy Matrix Composites Reinforced with Malva Fiber

et al. 2015

View full text Add to dashboard Cite

Polymer composites reinforced with natural fibers have been increasingly investigated and applied as engineering materials owing to their economical, technical, societal and environmental advantages. The malva fiber, particularly an important resource in the Amazon region in Brazil, only recently begin to be investigated as possible composite reinforcement for engineering application. However, the mechanical properties of composites reinforced with malva fiber are still unknown. In this paper, the flexural behavior of epoxy matrix composites reinforced with continuous malva fiber was for the first time investigated. Specimens of continuous malva fibers aligned along an epoxy matrix were press-molded. Three-points bending test were performed and the fractured specimens were analyzed by SEM. The results showed a marked improvement in the composites flexural properties with the increase in the amount of reinforced malva fiber. This improvement was found to match the Rule of Mixtures, which revealed the unique potential of malva composites for engineering applications.
