“…Vazquez et al [186] studied the effect of mercerization, acrylation, isocyanate treatment and washing with alkaline solution of bagasse fiber on the tensile properties of bagasse-PP composites and it was found that chemical treatments enhance the tensile properties of composites. Tensile properties (modulus and tensile strength) of chemically treated short sisal fiber reinforced cellulose derivatives/starch composites with different fiber loading showed comparable results as that of calculated values obtained from the existing theories of reinforcement [187].…”

In recent years, natural fibers reinforced composites have received much attention because of their lightweight, nonabrasive, combustible, nontoxic, low cost and biodegradable properties. Among the various natural fibers; flax, bamboo, sisal, hemp, ramie, jute, and wood fibers are of particular interest. A lot of research work has been performed all over the world on the use of natural fibers as a reinforcing material for the preparation of various types of composites. However, lack of good interfacial adhesion, low melting point, and poor resistance towards moisture make the use of natural fiber reinforced composites less attractive. Pretreatments of the natural fiber can clean the fiber surface, chemically modify the surface, stop the moisture absorption process, and increase the surface roughness. Among the various pretreatment techniques, graft copolymerization and plasma treatment are the best methods for surface modification of natural fibers. Graft copolymers of natural fibers with vinyl monomers provide better adhesion between matrix and fiber. In the present article, the use of pretreated natural fibers in polymer matrix‐based composites has been reviewed. Effect of surface modification of natural fibers on the properties of fibers and fiber reinforced polymer composites has also been discussed. POLYM. ENG.

“…It was also observed that there was a reduction in the flexural strength of the material by mixing the bagasse fiber in the matrix. Vazquez et al (1999) developed bagasse-fiber-reinforced polypropylene composites. Different chemical treatments like isocyanate, acrylic acid, mercerization, and washing with alkaline solution of the vegetal fibers were performed to enhance the interface adhesion with the thermoplastic matrix.…”

As an important branch of the composite materials field, natural fiberreinforced polymer composites have been studied for decades. Natural fibers are originated from several sources such as cotton, nut, shells, bagasse, corncobs, bamboo, and vegetable. This work aims to discuss the different surface modification techniques of bagasse fibers including alkaline, silane, acetylation, and benzoylation treatments. The chapter also deals with the discussion on processing techniques of bagasse fiber-reinforced composite manufacturing and its mechanical and morphological properties. It also covers advantages of bagasse fiber reinforcement in composites and future trends and applications.

“…They offer the best compromise between elongation at break, tensile strength, specific modulus, price and availability [3,9,10,[28][29][30][31][32][33][34][35][36]. Ramie fibres are the stiffest and the strongest fibres and would be the best choice if they were more available.…”

In recent years, many car manufacturers such as Audi, BMW and Ford have developed natural fibre composite components. The driver behind developing interior parts with natural fibres as reinforcement is to save weight without compromising mechanical properties, with the additional benefit of moving towards a more sustainable part production. Current biocomposites are based on the application of short, non-woven natural fibres. However, bonding hydrophilic natural fibres to a hydrophobic polymeric matrix can sometimes lead to a relatively poor interface, mostly because of the different polarities of the two components. In addition, natural fibre composites are highly sensitive to water absorption. The aim of this study was to compare the physical properties two biocomposites: (1) a flax/bio-based epoxy and (2) a flax/polyurethane. In fact, polyurethane is synthesized by polyaddition of an poly-isocyanate and a polyol, an alcohol containing several hydroxyl groups. Flax fibres are mainly composed of cellulose, a natural polymer that presents multiple hydroxyl groups. A crosslinking reaction between the polyurethane matrix and the cellulose in the fibres could increase the interface strength. Both materials were manufactured using a resin transfer moulding (RTM) process in order to maximize the fibre volume fraction and were reinforced with the same flax woven fabric.Composite samples were then aged at 90% RH and 30°C. The results showed that both composites followed a Fickian diffusion behaviour and that flax/polyurethane composites were less sensitive to moisture ageing than flax/bio-epoxy composites. The chemical bonds between the hydroxyl groups of the fibres and the isocyanate lead to a stronger interface which improved the mechanical properties as compared to the flax/bio-epoxy composites. When exposed to moisture, the flax/polyurethane composites show more stable mechanical performances, especially the short beam strength, the compressive strength and the compressive modulus.Scanning electron micrographs were taken to look at the interface between the flax elementary fibres and the polymer matrix and clearly showed a better fibre/matrix adhesion in the case of the flax/polyurethane composites. Finally, dynamic mechanical analysis (DMA) was performed to study the evolution of the glass transition temperature ( ) in function of the water uptake for composite samples immersed in distilled water at 30°C. III ABREGEDepuis plusieurs années, de nombreux constructeurs automobiles dont Audi, BMW et Ford ont développé des pièces en composite renforcés par des fibres naturelles. Le développement de composants pour les intérieurs de voiture renforcé par des fibres naturelles permet d'économiser du poids sans pour autant compromettre les propriétés mécaniques, avec l'avantage supplémentaire de produire des pièces dans un matériau plus durable. Les biocomposites actuels contiennent surtout des fibres naturelles courtes, non-tissés. Toutefois, l'adhésion de fibres naturelles hydrophiles à une matrice polymère hydrop...
