“…[9] Thermal stability decreases slightly upon increasing alkali concentration beyond 5%. [10] This study aimed to optimize alkali treatment for Prosopis juliflora fibers (PJFs) and understand crystallinity, structural composition, tensile properties, and thermal stability of the optimally treated PJFs by XRD, Fourier transform-infrared (FT-IR) spectroscopy, tensile testing, and thermogravimetric analysis (TGA).…”

There is ever-increasing interest in using natural fibers in polymer composite systems and textile industry. Prosopis juliflora fibers (PJFs) possess ideal characteristics that make them suitable for various applications. Alkali treatment of PJFs was primarily aimed to change their physico-chemical properties; 5% (w=v) NaOH concentration and 60 min of soaking time were found to be optimal. It is intriguing to note that optimally treated PJFs had higher cellulose (72.27 wt.%), lower hemicellulose (4.02 wt.%) and lignin (12.09 wt.%) contents, higher crystallinity index (73%), tensile strength, and thermal stability.

“…Care was taken to achieve a uniform distribution of fibers while being layered in the LDPE matrix. Secondly, an electrical oven was used to mix the composite constituents at 300˚C (AlMaadeed et al 2013) until the matrix fully encapsulated the fibers as shown in Fig.1(b). Sheets were manually pressed under 25 kg load for 15 minutes to eliminate any porosity or void formation and maintain a uniform thickness as specified.…”

“…Chemical treatment of fiber helps in removing sticking dirt and improving its physical and chemical characteristics. AlMaadeed et al (2013) and Shalwan et al (2016) reported that the use of high NaOH concentration can cause deterioration in the fiber strength. Also, Alawar et al (2009) concluded that hydrochloric acid treatment resulted in deterioration in its mechanical properties.…”

Characterization of Mechanical Properties of Aligned Date Palm Frond Fiber-Reinforced Low Density Polyethylene

Abstract: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.

“…Alkali pre-treatment is effective in tropical wood polymer composites (Islam et al 2012). Comparing male and female date palm leaves, AlMaadeed et al (2013) found that alkali-treated female leaves had better tensile properties. Anbukarasi and Kalaisevam (2015) investigated the effect of fiber volume, dimension, and alkali treatment on the luffa reinforced epoxy composites.…”
