“…SPF has limited applications in polymer composites, except with some epoxies (Bachtiar et al 2008(Bachtiar et al , 2009 and high impact polystyrene (Bachtiar et al 2011(Bachtiar et al , 2012. However, the role of the SPFs as reinforcements in the thermoplastic composites with TPU has not been studied.…”

The physicochemical properties of an innovative and environmentally friendly composite material based on sugar palm fiber (SPF) and thermoplastic polyurethane (TPU) were examined. The base material with short fibers was extruded and hot pressed to produce the TPU-SPF composites with different synthetic parameters. Operating parameters including temperature for extrusion (170 to 190 °C), rotational velocity (30 to 50 rpm), and fiber particle sizes (160, 250, and 425 µm) were investigated. The aims were to optimize rotational velocity, temperature, and fiber size of the TPU-SPF composites. Firstly, the influence of rotation of velocity and temperature on the tensile properties was investigated. Secondly, effects of different fiber sizes on tensile, flexural properties, and impact strength as per ASTM standards were tested. The morphological, thermal, and physicochemical properties of the synthesized TPU-SPF composites were ascertained with Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), X-ray diffraction (XRD), and thermogravimetric analysis (TGA). The optimal results were observed with a temperature of 190°C and a rotational velocity of 40 rpm. Meanwhile, the strength and modulus for tensile and flexural were best for fiber size 250 µm. Moreover, the impact strength reached a peaking trend at 250 µm fiber size.

“…Different weights of NaOH were dissolved in a flask with distilled water for three different time periods, then left to stand for around 30 minutes to let the solution become homogeneous and cool. Then, after soaking in sodium hydroxide solution for 90 minutes, finally the fibre was washed in distilled water eight times [13,27,28]. Thereafter, the fibre was left to dry for around two weeks at atmosphere pressure and room temperature [13].…”

“…The following Scheme 1 explains the mechanism of the reaction between the natural fibre and the NaOH solution [26]. It is clear that the OH groups are separated from the fibre by the action of the Na +2 ions to produce a new component which is (fibre-NaO) instead of (fibre-OH) [13,[26][27][28].…”

Global warming, environmental changes, and other problems have been increasing in the last decade. Researchers and scholars want to safeguard life on the earth by making ecofriendly products, like natural composite materials. Natural fibre is environmentally valuable because of its biodegradable nature. However, there is a serious problem caused by the incompatibility between fibre and matrix. In this work, sugar palm fibre was combined with thermoplastic polyurethane composites after treatment with different concentrations of sodium hydroxide from 2 to 6% to enhance the compatibility between them. An extrusion machine was used to combine 30% by weight of the sugar palm fibre and 70% by weight of thermoplastic polyurethane composites. The temperature, rotation velocity, and fibre size were fixed at (180-190-200°C), 40 rpm and 250 µm respectively. The composite was characterized according to ASTM D638. The sodium hydroxide treatment of the fibre could provide a good tensile modulus of 440 MPa at 2% of NaOH, and strain of 41.6% at 6% NaOH of the composite. However, the tensile strength was decreased, where the highest amount of 5.49 MPa recorded at 6% NaOH. Meanwhile, the tensile modulus and strain of the composites are found to be much better than those of untreated ones. In contrast, the tensile strength was still not improved.

“…Strong interfacial interaction and firm adhesion between modified fibers and the matrix interfaces resulted in relatively high impact strength among modified fiber filled composites as compared with those filled with raw fibers. Alkaline treatment is reported to remove the lignin and hemicellulose, leading to better packing of cellulose chains and maximum fiber crystallinity that contributes to the toughness of the composite and hence improved impact strength of the composite (Bachtiar et al 2009). Nevertheless, in this case also the impact strength tended to decrease with the increase in filler loading.…”

Lemongrass fiber was analyzed to determine the chemical proportion of its lignocellulosic components. Fibers' thermal behavior, surface structures, and functionality were assessed by thermogravimetric analysis (TGA), scanning electron microscope (SEM), and Fourier transforminfrared spectroscopy (FT-IR), respectively. High-density polyethylene (HDPE) matrix composites filled with varying (10%, 20%, 30%, 40%, and 50%) fiber content were prepared and investigated. Composite wicker was made from HDPE and low density polyethylene (LDPE) blend-matrix and 10% alkaline modified fiber. Alkaline or maleic anhydride grafted polypropylene (MA-g-PP) was used to improve the compatibility between the fiber and matrices. The composites were evaluated by using TGA, SEM microscopy, and universal testing machine, respectively. The fiber was constituted by equitable amounts of lignocellulosic components with cellulose accounting for the highest proportion. It also exhibited high degradation temperature, which was further increased following alkaline modification. Superior thermal degradation behavior was measured for modified fiber composites. SEM showed that the modified fiber composites demonstrated better compatibility. Lemongrass fiber reinforcement substantially improved the mechanical properties of the composites.
