摘要

Palm trees generate vast amounts of agricultural residue annually, yet only a tiny fraction is used. This work aims at analyzing the use of palm leaflet fibers as potential reinforcement in composite materials. The leaflets fibers are extracted from the date palm (DPLF) and from the Washingtonia palm (WPLF), which are abundant in all regions of Algeria. The morphology of the two types of leaflet fibers was examined by SEM and by FTIR, TGA, DSC, and XRD. Static tensile tests have shown a strong variation of the mechanical response along the length of the types of leaflets. For this reason, leaflets were then separated into distinct top, middle, and bottom parts. The more significant mechanical response was obtained for the top part of the leaflets. Date palm leaflet fibers exhibit 162% higher stress, 44% greater strain, and 81% higher Young’s modulus compared to Washingtonia palm leaflet fibers. Given the substantial variability in the results, multiple statistical methods were applied. The three-parameter Weibull distribution proved to be the best fit for the experimental data.
