“…At the initial stage of the tensile test, a delay in fracture process was also observed, when fibers separated from the polymer matrix. Following this, small cavities were generated in samples filled by sand particles, which this process is so called pulling and fracturing mechanism of the fibers as discussed by Ahmad et al [11]. In addition, this improvement can be attributed to the good dispersion of date palm fiber and dune sand particles within the matrix, this result is in line with those showed in presence of (5wt%) Luffa fiber, (5wt%) CaCO3 and Polyester-based matrix [27].…”

“…Ahmad et al [10,11] also conducted a research on the epoxy and polyester-based composites to study the influence of nanoparticles of Tronoh silica sand as well as glass fiber on the mechanical and thermal properties of the systems. The results showed that addition of nanoparticles improved the mechanical and thermal properties of the developed composites.…”

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).

“…As seen in Table 5, HV hardness values of the silanecoated nano SiO2 filled glass FRP composites were determined higher than that of pure glass FRP composite. This is because the presence of the nanoparticles did not allow the indenter to penetrate deeper [25]. However, the increments vary depending on both silane coating and filler percent within the polymer matrix.…”

In this study, silane-coated SiO2 nanoparticles (as-received) were used as secondary reinforcement for glass fiber-reinforced polymer (FRP) composites, and the microhardness values of the developed composites were investigated. The nanoparticles were dispersed within the polymer epoxy at 1.5 wt.% and 3 wt.% ratios, respectively. Two different types of silane coating were used that were KH550 and KH570. The mixture of the epoxy resin and nanoparticles were subjected to ultrasonic homogenization to achieve a fine dispersibility of the SiO2 nanoparticles. Then the matrix was prepared with a suitable hardener at a weight ratio of 100:25. The strengthened polymer matrix was reinforced by woven glass fiber fabrics (primary reinforcing element). The vacuum bag method was applied to produce silane-coated nano SiO2 filled glass FRP composites. A digital microhardness testing device was used to determine the Vickers hardness values. While the pure glass/epoxy composite has resulted in a hardness of 20.69 HV, the maximum hardness value was recorded as 36.56 HV and it was obtained with 3 wt.% KH550-SiO2 filled glass/epoxy. The incorporation of silane-coated SiO2 nanoparticles has provided dramatic enhancements, approximately from 28% to 77%. The microscopic examination was also conducted via an optical microscope and the images were found helpful to explain the test results. Therefore, the findings of this study have shown that silane-coated nano SiO2 filler can be used as secondary reinforcement where high hardness and better wear resistance are desired for glass/epoxy composite applications.

“…In the same logic of reflection, Ahmad et al [4][5][6] carried out studies on composites based on epoxy resins and polyesters, looking for the influence of silica nanoparticles (sand) on the mechanical and thermal properties of the composite system. Also, Meftah et al [7] explored the influence of alkaline treatment, and dune sand on the properties of DPLF date palm fiber reinforced with unsaturated polyester by forming hybrid composite systems.…”

In order to improve the properties of unsaturated polyesters, this study discusses the possibilities of developing a natural waste, date palm leaf fiber DPLF, produced in the northern Algerian Sahara, associated with the polymer matrix of a thermosetting polyester resin UP. For this purpose, composite plates containing virgin fiber at rates of 6 and 10% were treated with an alkaline solution of 6% NaOH on the one hand, and a silane compound on the other. In this research, a mechanical study of strength and elongation at break was carried out. In addition, morphological behavior was followed by SEM scanning electron microscopy. ATG thermogravimetric analysis and energy flow were monitored by DSC differential scanning calorimetry. Also, a study of the water absorption capacity has been conducted. In addition, a dynamic mechanical analysis DMA was carried out. The findings of this study show that there is a favorable mechanical behavior for the composites containing the 6% and 10% DPLF fiber, with alkaline NaOH and Silane treatment. They also show that the chemical treatment with alkaline solution and silane gives composites certain thermal stability compared to those with untreated fiber. Findings also explore that the absorption of water by the various composites shows that the chemical treatment promotes some intermolecular associations with water. Findings also show that the storage modulus (E') increases when the composite contains 10% DPLF, treated and untreated, and the maximum value of the tangent moves towards the high temperature for the treated and untreated fiber composite.
