In recent decades, natural fibers have received attention of scientists and researchers due to their ecofriendly characteristics that qualify them as potential reinforcement in polymer composites in place of synthetic fibers.  In this study, an experimental investigation has been conducted to evaluate the effect of orientation of fibers on mechanical properties of a newly developed bio-composite in which date palm fronds (DPF) are embedded as fibers in low-density polyethylene (LDPE) matrix. Three bio-composite sheets with orientations of 0°, 45° and 90°, respectively have been fabricated after the date palm fronds were chemically treated. The fabricated composite specimens are tested under tensile load using Universal Testing Machine (UTM) in accordance with the ASTM D-638 standard. Then, a comparison of the experimental results against analytical results is made to examine the accuracy and agreement between the two. An inconsistency in moduli, as was discovered, is attributed to the adhesion quality between the fibers and surrounding matrix. Output results help to assess the applicability of such class of bio-composites in real-life applications.  The results of tensile strength, Young’s modulus, and elongation at break revealed that date palm fronds can be used as reinforcement material in polymer-based composites for low strength applications.

Linear Low Density Polyethylene

This work aims to develop green linear low-density polyethylene (LLDPE) composites that are commercially viable due to the low cost of the date palm leaflet filler, which is a local renewable resource. The filler was naturally treated with gum arabic solution. FT-IR, XRD, and SEM techniques were used to characterize the samples. The thermal and mechanical properties were measured by TGA, DSC, and tensile testing. The results showed noticeable changes in the properties of the composites compared to those of the original LLDPE sample. TGA revealed that the composite started thermally. The composites started thermally degrading before the original polymer, owing to the degradation of the natural components in the filler. The findings from DSC suggested that the crystallinity was affected. The tensile testing results indicated that the composites were appropriate for applications requiring low tensile strength at break and high Young’s modulus. A comparison of these results with earlier ones exhibited that the basic additives in the polymer may have an effect on the filler performance.

Abstract The circulation of recycled low density polyethylene (r-LDPE) globally, using Nigeria as point of reference is emphasized in this work. The need for combining r-LDPE with a less expensive organic fiber as an economical alternative material in panel production for printer component to reduce waste through recycling. In this study, the particle size (PS) and fiber content (FC) of date palm wood fiber (DPWF) in a r-LDPE matrix are essential factors to be considered for optimizing flexural strength (FS), flexural modulus (FM) and Izod impact strength (IIS) of r-LDPE-DPWF (recycled low density polyethylene-date palm wood fiber) composite for producing printer components. The variant FC and PS of the DPWF was compounded in r-LDPE matrix to optimize the FS, FM and IIS of r-LDPE-DPWF composite, using a central composite design (CCD) as a response surface methodology (RSM). The DPWF and r-LDPE-DPWF composite were analyzed by Fourier transformed infrared (FTIR). The results indicated that the FS, FM and IIS of r-LDPE-DPWF composite measured 46.66002 MPa, 1.150043 GPa and 1.99899 KJ × m-1 at optimal operation, respectively. Under these operating conditions, PS and FC were 60.78 mesh (250 μm) and 30 wt.-%, respectively. Finally, the main coefficient of determination (R2) for the factors correlated with the characteristics of the r-LDPE-DPWF composite at an approximate value of 1 with a differential error of RSM and experiment values < 0.05 %. It was concluded that the RSM model yielded the necessary parameters for the r-LDPE-DPWF composite to be considered as a potential material for printer components.
