“…Japan is similarly strict, requiring 88% of the vehicles to be recovered in 2005 (recovery grants for incineration of some components), rising to 95% by 2015 [238]. In Brazil, car manufacturers, such as Volkswagen, Ford, Honda and General Motors already apply natural fibre in car seats, dashboard coverings, roofs and trunk lids [239].…”

“…Initially, PFRCs by using non-woven forms of plant fibers were developed in automotive sectors given their low density, low cost, and environmentally friendly characteristics to these parts [4]. Manufacturers, however, have since learned that these materials offer both structural and damping benefits [5][6][7].…”

Plant fiber-reinforced composites have raised great attention among materials scientists and engineers during the past decade. Most of the efforts were put on the interfacial modifications to improve the mechanical properties of the composites so that they could partly replace the currently largely used glass fiber-reinforced composites. The modifications were mainly focused on the surface treatment of plant fibers so that mechanical or chemical bonding between plant fibers and polymeric matrices could be set up. However, the unique hierarchical microstructures of plant fibers make the building up of multiscale interfaces possible so that more forces or energies would be needed to fracture the plant fiber-reinforced composites. The additional hollow structures could also bring benefits for sound absorption and damping properties. Therefore, this article reviewed R&D efforts to develop structural and functional-integrated plant fiber-reinforced composites by fully taking advantage of the hierarchical microstructures of plant fibers. Firstly, the unique hierarchical structures of plant fibers were revealed and hierarchical theoretical models for mechanical properties were discussed. Then, the modification, characterization, and evaluation of plant fibers in terms of their interfacial properties with polymeric matrices, especially by nanotechnologies with the consideration of their unique hierarchical microstructures, were reviewed. Finally, the design and manufacture of quasi-structures and structural-damping components using technologies that have been fully adapted to state-of-the-art industrial processes for use in critical applications, such as aircraft interiors, rail transportation vehicles, and constructions, were also introduced.

Chemical modification of fiber surfaces can increase wettability of composites reinforced by vegetal fibers and, consequently, the dispersion of the fiber in the matrix and mechanical properties can be improved. Although there are some studies about agents for chemical modifications of vegetal fiber surfaces, there are few data and discussion about the usage of lignin. In the present work, chemical modifications of sugarcane bagasse and sisal fibers using lignin (previously hydroxymethylated) were carried out under different reaction times (15, 30, and 60 min). The composition (holocellulose, hemicelluloses, cellulose, and lignin contents) of the treated and untreated fibers was evaluated. Phenolic composites were prepared using unmodified and modified fibers via compression molding process under temperature. Izod impact, water absorption tests, and scanning electron microscopy were performed to evaluate composite properties. The resin and lignin were characterized by size exclusion chromatography. Results showed that there was a tendency of reducing water absorption for composites prepared from modified fibers. Impact strengths of composites reinforced with sugarcane bagasse with modified fibers were similar to the ones with unmodified fibers (around 20 J/m). However, impact strengths for composites reinforced with modified sisal fibers (around 104 J/m for 15 min of reaction time) were higher than the ones with unmodified fibers (around 95 J/m). Therefore, the usage of lignin as a modifier agent of vegetal fiber surfaces to increase fiber–matrix adhesion for phenolic composites is a strategic alternative for improving products through simple, eco-friendly, and low-cost procedures.
