Polymer composites have good mechanical, friction, durability, and wear performance after being reinforced with waste or nanofiller. These features make them flexible in many structural applications. This study was carried out to improve the mechanical performance of polymer composites using silica-based, waste, and nanomaterials. To achieve this, marble dust of millimeter size, silica fume of micrometer size, and Nano-SiO(2)of nanometer size were added separately or in combination to the polymer matrix. The samples were tested to obtain the compressive strength, tensile strength, ultrasonic pulse wave velocity, dynamic modulus of elasticity, toughness, and density of reinforced polymer composites. The results of the tests on the polymer composites indicated that the best ratios were 30%, 5% and 1% for separately added marble dust, silica fume and nano-silica groups, respectively, while the contribution of nano-silica to marble dust/silica fume was the optimum when added by 1%. Moreover, the results showed that adding marble dust to polymer composites increased ductility while adding silica fume and nano-silica reduced the ductility of the samples. Additionally, the microstructural properties of the polymer composites with waste marble dust and silica fume, and nano-SiO(2)additives were evaluated using a scanning electron microscope (SEM) to provide a close relationship between the morphological structure and mechanical properties. This study opens up a new way for added value using waste materials like marble dust/silica fume as well as nanomaterials in polymer composite applications.
