In this study, the effect of different polypropylene (PP) matrices (homopolymer (HPP), impact copolymer (ICP), and recycled polypropylene (rPP)) on the mechanical, morphological, and thermal properties of date palm fiber (DPF)-reinforced PP composites was investigated. The DPFs were treated with an alkali solution, and composites were fabricated with different DPF loadings (5, 10, and 15 wt %) and lengths (less than 2 mm and 8–12 mm). It was found that the tensile properties of the DPF/ICP and DPF/rPP composites were similar to those of the DPF/HPP composites. The addition of fiber to the matrix reduced its tensile strength but increased the modulus. The alkali treatment improved the compatibility between the fibers and the matrix by removing hemicellulose and other impurities. Fourier transform infrared spectroscopy confirmed hemicellulose removal. The morphology of the alkali-treated fractured tensile specimen revealed improved adhesion and less fiber pull out. Differential scanning calorimetry revealed that the alkali treatment enhanced the crystallinity index. Thermogravimetric analysis showed that the addition of DPFs into the PP matrix reduced the thermal stability of the composite. However, the thermal stability of the treated fiber-reinforced rPP and ICP composites was similar to that of the DPF/HPP composite. Hence, rPP can be used as an alternative to HPP with DPFs.

This paper aims at introducing and investigating the mechanical properties of new variety of natural fibers (Christmas palm fiber) used as reinforcement in polymer matrix composites. It was inferred that the poor inter laminar bonding between the Christmas palm fibers and polyester matrix restricted the mechanical properties of the composites. Hence surface modifications of Christmas palm fibers by means of alkali treatment were done in a view to enhance the bonding nature of the Christmas palm fiber with polyester matrix. The composite fabrication is carried out using compression moulding machine and the mechanical properties were tested as per ASTM standards. The effect of soaking time and solution concentration of Sodium hydroxide on the mechanical properties of Christmas palm fiber reinforced polyester composites were studied and fiber treatment conditions for better mechanical properties are identified. Scanning electron microscopy (SEM) investigations showed that surface modification improved the fiber/ matrix adhesion which in turn enhanced the mechanical properties of the Christmas palm fiber reinforced polyester composite.
