“…Remarkably, fibrous bundles or the honeycomb morphology are also visible in the SEM images of all the DPF/epoxy composites. Relatively similar honeycomb structures were noticed in the fracture surface morphology of unidirectional composites comprising date palm petiole fibers [32] and in the surface morphology of untreated date palm petiole fibers from the region of Tozeur (Southern Tunisia) [33].…”

The present study deals with the fabrication of epoxy composites reinforced with 50 wt% of date palm leaf sheath (G), palm tree trunk (L), fruit bunch stalk (AA), and leaf stalk (A) as filler by the hand lay-up technique. The developed composites were characterized and compared in terms of mechanical, physical and morphological properties. Mechanical tests revealed that the addition of AA improves tensile (20.60–40.12 MPa), impact strength (45.71–99.45 J/m), flexural strength (32.11–110.16 MPa) and density (1.13–1.90 g/cm3). The water absorption and thickness swelling values observed in this study were higher for AA/epoxy composite, revealing its higher cellulosic content, compared to the other composite materials. The examination of fiber pull-out, matrix cracks, and fiber dislocations in the microstructure and fractured surface morphology of the developed materials confirmed the trends for mechanical properties. Overall, from results analysis it can be concluded that reinforcing epoxy matrix with AA filler effectively improves the properties of the developed composite materials. Thus, date palm fruit bunch stalk filler might be considered as a sustainable and green promising reinforcing material similarly to other natural fibers and can be used for diverse commercial, structural, and nonstructural applications requiring high mechanical resistance.

The effects of alkali treatment and dune sand (DS) addition on the mechanical, morphological, thermal and water absorption behavior of date palm fiber (DPF) reinforced unsaturated polyester (UP) composites were investigated. The composites were synthesized by hand lay-up method with 10, 20, and 30 wt% of both treated and untreated date palm fiber (TDPF/DPF). Furthermore, composites having 10, 20 and 30 wt% of untreated date palm fiber and dune sand (both of them were in equal wt%) were also fabricated. Alkali treatment improved the tensile strength, tensile modulus, flexural strength and flexural modulus of the resulting composites. Scanning electron microscopy (SEM) revealed the better interfacial interaction of treated date palm fibers/UP composites. Thermogravimetric analysis (TGA) showed that thermal stability, and degradation temperature of treated DPF composites were best over the untreated DPF composites. Water absorption test indicated the decreasing of hydrophilic character of the filler after treatment with sodium hydroxide (NaOH). Overall analysis represented that satisfactorily improved physical properties of UP for various engineered and hi-tech applications were obtained with 10 wt% fillers loading (5 wt% date palm fiber and 5 wt% dune sand particles).

Currently, the manufacture of composite structures often requires material removal operations using a cutting tool. Indeed, since biocomposites are generally materials that do not conduct electricity, electro-erosion cannot be utilized. As a result, the processes that can be used are limited to conventional machining, called chip removal machining, such as drilling.Delamination factors are widely recognized for controlling the damaged area (delamination) induced by drilling in industry. As discussed in the literature, several approaches are available to evaluate and quantify the delamination surrounding a hole. In this context, the objective of this study is to compare the three Fd evaluation methods that have been most frequently used in previous investigations. To this end, three rotational and feed speeds and three BSD tool diameters were selected (L27) for drilling 155 g/m 2 density jute fabric reinforced polyester biocomposites. The response surface methodology (RSM) and artificial neural networks (ANNs) were applied to validate the results obtained experimentally as well as to predict the behavior of the structure depending on the cutting conditions.
