“…On the other hand, the valley shaped region between the two major peaks signifies the non-crystalline region of TTF, which represents the amorphous materials in cellulose, hemicellulose, lignin and other non-cellulose materials. Similar peaks were reported for raw sisal fibers and oil palm empty fruit bunch by Kaushik et al (2012) and Rayung et al (2014), respectively. The crystallinity index of TTF is calculated to be 43%.…”

“…The crystallinity index of TTF is calculated to be 43%. This value is higher than the crystallinity index values reported by Edhirej et al (2016) and Kaushik et al (2012) for cassava peel and sisal fiber, respectively. The obtained crystallinity index of TTF is also higher than that of jute (34.3%), kenaf (34.9), and ramie fiber (34.8) reported by Poletto et al (2014).…”

The tea tree (Melaleuca alternifolia) is well known for producing essential oil, which is used in medicinal and cosmetic products as a preservative, antiseptic, antibacterial, antifungal, and anti-pest additive. In this study, tea tree residues generated as agro-waste after the tea tree oil extraction process were utilized as cheap fiber material for the reinforcement of sugar palm starch (SPS)-based composite films. The crystallinity and functional groups of tea tree fiber (TTF) were investigated and the effect of TTF loading (0, 1, 3, 5, and 10 wt.%) on the tensile and morphological properties of TTF/SPS composite films were investigated. As the TTF loading increased from 0 to 10 wt.%, the tensile strength and modulus of TTF/SPS composite films were significantly increased, but their elongation at break declined. Optical microscopic and scanning electron microscopic images revealed that the TTF was randomly dispersed in all samples, and there was optimal compatibility between the fiber and matrix. Based on these findings, TTF can be considered as a potential reinforcement material for polymer composite films.

“…The diffraction spectra analyzed in this study were collected from a 2θ angle of between 10° and 80° scanned at a speed of 0.05°/s. The percentage crystallinity of raw and treated Christmas palm fibers was computed using the following formula [18,19] where I 002 and I am are the crystalline and amorphous intensities at 2θ scale, respectively. The change in surface topography of the treated Christmas palm fibers and its physicochemical interaction with polyester matrix were characterized using scanning electron microscopy (SEM, Hitachi S-3000N, Hitachi, Haryana, India) operated at 20 kV.…”

The mechanical properties of Christmas palmreinforced polyester composite were improved by chemical modification of Christmas palm fibers through alkali treatment. An attempt was made in this investigation to identify the possibility of using potassium hydroxide as alkali solution. The fibers treated with potassium hydroxide aqueous solution at varying solution concentrations and soaking times were reinforced in a polyester matrix and tested for their mechanical properties. The physicochemical interaction between the treated Christmas palm fiber and polyester matrix was characterized using scanning electron microscopy and X-ray diffraction. The surface modification of fibers improved the compatibility of fibers with polyester matrix, which, in turn, resulted in better mechanical properties. A nonlinear regression model was developed to predict the mechanical properties of the composites using response surface methodology. The better treatment conditions for optimum mechanical properties were determined using a heuristic optimization method called particle swarm optimization (PSO). The optimized value obtained using the PSO technique was validated through a confirmation test, and the result was found to be significant.

“…As the natural fibers contain hydroxyl groups from cellulose and lignin, their surface needs to be modified with different chemical treatments to enhance the effectiveness of interfacial bonding (Ali et al 2016b;Militký and Jabbar 2015). Recently, mercerization, acrylation, acetylation as well as isocyanate, permanganate, silane and peroxide treatments of natural fibers have been adopted as successful improvement of fiber strength and reported in the literature (Li et al 2007;Kaushik et al 2013;Valadez-Gonzalez et al 1999;Ray et al 2002;Herrera-Franco and Valadez-Gonzá-lez 2005;Wong et al 2010).…”

In this study, cereal straw was alkalized and treated with benzoyl or dicumyl peroxide solution. Modified straws were adopted as cellulosic filler in natural rubber biocomposites. Morphological changes and thermal stability of fillers were investigated by scanning electron microscope, Fourier-transform infrared spectroscopy and thermogravimetric analysis technique. The influence of both treated and untreated cereal straws on the rheometric characteristics, static and dynamic mechanical properties, crosslinking density and resistance to aging of composites was examined. Modified straws showed better thermal resistance compared to raw fibers and were resistant up to about 220°C. The results indicated that the strongest reinforcing effect was achieved using 10 phr of treated cereal straw. Deterioration of the mechanical properties of composites is observed in composites with a higher content of biofiller (20, 30 phr). It might be the result of a strong agglomeration of crumbled straw particles acting as stress cumulative elements in the vulcanizate. Dynamic mechanical analysis revealed the reduction in the tangent delta of treated composites, might be due to improvement in filler/matrix interfacial adhesion. Moreover, all of the vulcanizates proved to be resistant to thermo-oxidative degradation. Cereal straw represents an interesting alternative for commercial fillers and could be successfully applied as a low-cost biofiller, which improved several properties of elastomer composites.
