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).

 The tensile test revealed that the latest mix has the better modulus of elasticity at (3% wt).  This nanocomposite material showed very good roughness, hardness, flexural, and impact resistance.  The good dispersion of the nanoparticles had a great role in having this material good properties as aggregation may lead to a decrease in the quality of the properties.In this work, unsaturated polyester, resin, matrix reinforced, with fiberglass mat chopped were developed using TiO 2 and SiO 2 Nanoparticles as filler materials.The individual and combined effects of nanoparticles on the nanocomposite and material properties were examined. An improvement in Young's modulus (39,3%) using combined weight of TiO 2 + SiO 2 was observed to be 3%.Examined nanoparticles have shown normal distribution in grain size indicated to be within standard limit, therefore boosting nanocomposite material to have excellent hardness, roughness, impact, and flexural resistance. DSC was characterized by transitions in this material. SEM and EDS techniques were used to confirm the formation of TiO 2 and SiO 2 . The nanocomposites can be used in light-shielding, applications as well as in the industrial sectors.

“…The results of the UPR showed an improvement in mechanical properties by the addition of a (FGD) gypsum filler. Using the hand lay-up technique, Ahmad et al 30 developed silica nanoparticles/glass fibers/UPR composites and reported that with addition of 4 wt % of both fillers the tensile strength of composites reached up to 78 MPa. de Souza et al 31 studied the mechanical properties of UPR filled with BC and pointed out that the tensile, flexural, and impact strengths decreased with increasing filler content.…”

In recent years, cheaply available cementitious materials (CMs) are increasingly finding useful applications in construction engineering. This manuscript focused on the development and fabrication of unsaturated polyester resin (UPR)/cementitious material composites to be potentially useful in a variety of construction applications. For this purpose, five types of powders from widely available fillers, i.e., black cement (BC), white cement (WC), plaster of Paris (POP), sand (S), and pit sand (PS), were used. Cement polymer composite (CPC) specimens were prepared by a conventional casting process with various filler contents of 10, 20, 30, and 40 wt %. Neat UPR and CPCs were investigated mechanically by testing their tensile, flexural, compressive, and impact properties. Electron microscopy analysis was used to analyze the relation between the microstructure and mechanical properties of CPCs. The assessment of water absorption was conducted. The highest tensile, flexural, compressive upper yield, and impact strength values were recorded for POP/UPR-10, WC/UPR-10, WC/UPR-40, and POP/UPR-20, respectively. The highest percentages of water absorption were found to be 6.202 and 5.07% for UPR/BC-10 and UPR/BC-20, while the lowest percentages were found to be 1.76 and 1.84% for UPR/S-10 and UPR/S-20, respectively. Based on the finding of this study, the properties of CPCs were found to depend on not only the filler content but also the distribution, particle size, and combination between the filler and the polymer.
