“…Furthermore, researchers have investigated the use of coal ash, a waste product from coal-red power plants, as a ller material in high-density polyethylene composites. The addition of coal ash actually improved the mechanical properties and thermal conductivity of the composite, suggesting that this approach could be useful in construction [9,10].…”

The construction industry is currently dealing with the task of finding consistent building materials. This study presents an advancement in construction materials through the development of a composite board tailored for ceiling applications. The board is engineered using waste materials by the coating method, in which sawdust and waste paper mixed with epoxy are sandwiched between two layers of recycled polyethylene terephthalate. It exhibited better properties, including a flexural strength of 4.42 MPa, minimal water absorption of 1%, low thermal conductivity, and a lightweight profile. Through a comprehensive comparative analysis of numerous composite boards studied before, the composite board emerges as the better choice across a spectrum of performance metrics. Leveraging waste materials in its formulation aligns with the principles of resource sustainability and a circular economy. The composite board's performance offered a promising solution to address environmental demands in contemporary construction practices. This highlighted the potential for waste materials to redefine the industry's landscape.

“…With this aspect, lots of studies were done to improve structural, mechanical, thermal, rheological properties of HDPE by using different secondary components in the form of particle or fibers. [7][8][9][10][11][12][13] As seen from these studies, the chemical character, particle size and shape, compatibility with the matrix, content level, dispersion and distribution of the filler has a critical and deciding role in the performance of the final composites.…”

This study mainly aims both to prepare well-shaped crosslinked 3,3,4,4,5,5,6,6,7,7,8,8,8 tridecafluorooctyl-4-(acrloyloxy) benzoate (ABCF13) polymer microspheres and to investigate the influences of the prepared microspheres addition on the crystallinity, thermal, mechanical and morphological features of high density polyethylene (HDPE). The suspension polymerization method was used for the production of well-defined microspheres and, the content of the microspheres varied from 1.0% to 10.0% in the composites. The characterization of crosslinked poly(ABCF13) microsphere-loaded HDPE composites were performed via powder X-ray diffraction, differential scanning calorimeter, universal mechanical (tensile and impact) testers and scanning electron microscope (SEM) techniques. According to the experimental findings, a and b unit cell parameters increased initially and reached maxima with the sample including 5.0% microsphere, which were followed by dramatic decreases, while c parameter remained relatively unchanged. Thermal analysis also showed that the melting temperature of HDPE reduced with the initial loading of the microspheres, then stayed at a plateau value of about 129°C due to the formation of lattice distortions, generation of microstructural disorders and the defects in the crystal structures. The mechanical test results revealed that there existed considerable improvements in tensile strength, modulus and impact strength. The maximum tensile strength 25.66 MPa, elastic modulus 499.30 MPa and maximum absorbed energy in the impact test 26.84 kJ/m2 (29%, 42% and 41% improvement, respectively) were achieved with the blend involving 5.0% microsphere. After the maxima, the mechanical characters depicted weakening trend as the microsphere content increased in the matrix. The SEM analyses revealed that although there existed fibrillar formations in all samples, the extensions decreased with the increase of the microsphere content. While ductile behavior was observed with the formation of long-bulky extensions at low contents, brittleness started to prevail at high contents with some short and thin fibrils.

In the last few decades, Composites reinforced with natural fibre have generated more interest by researches and engineers due to their law density, high strength, low cost, light weight, recyclability and biodegradability and has gained a special category of green composite. In this work, wood dust reinforced epoxy composites were prepared with 20:80 % filler vol. zinc oxide nanoparticles (ZnONPs) sawdust/epoxy composites were synthesized by a simple casting method with five different ratios [0.1, 0.3, 0.5, 0.7 and 1% Vol.] of ZnONPs. The samples of the nanocomposites were characterized by the scanning electron microscopy (SEM) technique. The flexural strength and hardness tests were carried out to study the mechanical properties of the composites. From the observation it was found that the mechanical property increases up to certain filler 0.5 vol. % and then properties gradually decrease.
