AbstractEco-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.

AbstractIn recent years, natural fibers have received much attention from various industrial applications. As these fibers are lightweight, nonabrasive, low cost, ecofriendly and biodegradable, they can be sometimes considered as alternatives to synthetic fibers in lightweight composite structures. In this work, date palm fibers (DPFs) were treated by oxygen plasma at various plasma discharge power and exposure time. The effects of plasma treatment on tensile strength of DPF and interfacial adhesion between DPF and epoxy were determined by single fiber tensile test and microbond test, respectively. Scanning electron microscopy was used to investigate the surface morphologies of DPFs before and after the plasma treatment. The functional groups on the surface were studied by attenuated total reflectance-Fourier transform infrared spectroscope (ATR-FTIR). Decrease in hemicellulose and lignin content of DPF was indicated in ATR-FTIR spectra of the treated sample with plasma treatment. The results show that plasma treatment cleans the fiber surface and increases the surface roughness by etching effect. Moreover, fiber surface modification significantly improves tensile properties of DPFs and interfacial shear stress (IFSS) of fiber/matrix. However, the effects of plasma power and exposure time on tensile properties and IFSS values of DPFs are not found significant. Moreover, Weibull statistics show that plasma treatment could not decrease the variability in fiber strength due to the nature of fibers.

Interfacial properties of four kinds of natural fibers (et. ramie, jute, sisal and kenaf) reinforced phenolic resin were studied by single fiber pull-out test and short beam shear test. Effect of fiber surface treatments on the interfacial properties was evaluated. It showed that interlaminar shear strength (IFSS) was considerably improved after fiber surface treatments, especially after the silane treatment. Concerns about the poor moisture resistance of natural fibers, effects of fiber surface treatments on the moisture absorption behavior of natural fibers were also investigated by gravimetric methods. The results showed that neither fiber surface treatments nor the environmental temperature has effect on the moisture absorption behavior of natural fibers.
