RbstractThe need to develop and commercialize materials containing vegetal fibers has grown in order to reduce environmental impact and reach sustainability. Large amounts of lignocellulosic materials are generated around the world from several human activities. The lignocellulosic materials are composed of cellulose, hemicellulose, lignin, extractives and ashes. Recently these constituents have been used in different applications; in particular, cellulose has been the subject of numerous works on the development of composite materials reinforced with natural fibers. Many studies have led to composite materials reinforced with fibers to improve the mechanical, physical, and thermal properties. Furthermore, lignocellulosic materials have been treated to apply in innovative solutions for efficient and sustainable systems. This paper aims to review the lignocellulosic fibers characteristics, as well as to present their applications as reinforcement in composites of different polymeric matrices.

“…The thermogram clearly shows that MAPP treated composite is more stable than the other treated composites. The compatible blend formed between the PP segment of MAPP and the bulk PP present in the composite reacts with coir-sisal yarn, thereby forming covalent bonds across the interface Brought to you by | New York University Bobst Library Technical Services Authenticated Download Date | 6/18/15 11:11 AM between the coir-sisal yarn and PP surface which in turn increases the interfacial adhesion between them (17,18).…”

Eco-friendly bio-composite of polypropylene (PP)/coir-sisal blended yarn was prepared using commingling technique, in which both the fibers are wound onto a metal plate and then compression molded. Various chemical treatments have been done in order to improve the interfacial adhesion between the matrix and reinforcement, thereby to increase the properties of the composite. Thermal stability study was done using thermogravimetric analysis. The resulting thermogram reveals that chemical treatments increase the thermal stability of the commingled composite to a considerable extent. A significant increase is observed in the tensile properties of the treated composite especially maleic anhydride modified PP (MAPP) treated composite as compared to the untreated one. The tensile strength and tensile modulus of MAPP treated composite was found to be 29.24 MPa and 1330 MPa, respectively, which was found to be 7.5% and 6.4% greater than that of untreated composite. The experimentally observed tensile properties of the composites were compared with the existing models of reinforced composites. The surface morphology and fiber surface treatments were characterized by scanning electron microscopy and Fourier transform infrared spectroscopy.
