Description

Quartz-reinforced Polyester Composites (QPCs) weighing 10% to 40% quartz relative to the weight of unsaturated polyester resin has been created using compression molding. The properties of the composite were improved through synergistic improvements over those of the individual components. The physical and mechanical characteristics of the composite, including bulk density, water absorption, tensile strength, flexural strength, and hardness, have demonstrated its suitability for use in construction. It was discovered that the percentage of water absorption for the investigated resulting composite is relatively low. Water absorption, however, increased extremely slowly when the quartz content was raised. Improvement in mechanical characteristics is directly correlated with quartz's strong adhesion force to the matrix, which is impacted by well-dispersed quartz particles across the entire composite surface.

Many academics have recently concentrated on the use of some filler in a matrix. Because fillers and matrix interact well and improve the look of composites, fillers will be more favourable as matrix reinforcement. Numerous substances, including aluminium powder, carbon fiber, graphite, Precipitated Calcium Carbonate (PCC), silica, clay, kaolin, talc, quartz, and carbon black, have already been studied as fillers. Additionally, quartz has the ability to improve strength, adjust viscosity, be extremely resistant to weathering, and produce a smooth surface in comparison to the activity of sand (which is composed of a variety of minerals such as quartz, feldspar, mica, and other silicate minerals) as filler. This is because quartz contains a particular crystal form of SiO₂. Due to the formation of hydrogen bonds between the silanol groups on the quartz surface and the soft segments of ester carbonyl groups, the inclusion of quartz improves the thermal, rheological, mechanical, and adhesive properties of polyester. In-depth research has been done on the significance of coupling in highly filled particle composites as well as the fracture toughness, bending, and compression loading modes of quartz-filled unsaturated polyester resin composites with a silane coupling agent. In order to improve the physical, mechanical, and thermal properties of composite materials for a variety of applications, it is necessary to select an efficient reinforcement.

In the last few decades, individuals have been drawn to polymer matrix composites in materials research due to their relatively quick development and appearance in a variety of diverse fields of study. Due to their adaptability to a variety of settings and relative ease of combining with other materials to achieve desired features, composites are one of the most frequently used materials that have high physical, thermal, and mechanical capabilities compared to conventional materials. Nevertheless, composites are used as mirror housing in a variety of industries, including packaging, fuel cells, solar cells, fuel tanks, plastic containers, vacuum cleaner impellers and blades, power tool housing, and covers for portable electronic devices like cell phones and pagers. In these kinds of composite materials, a variety of polymers, including rubber, polylactic acid, polyvinyl alcohol, acrylic latex, polyethylene, and thermoplastic starch, are appropriate as the matrix. In addition, using a variety of matrices, unsaturated polyester resin is most frequently used to create advanced composite materials because it is economical, easy to handle, and can be used to fabricate complex parts with little investment in tooling. It also has excellent roomtemperature properties. As a result, polyesters were appropriate for a wide range of uses, with reinforced plastics being primarily used in the marine and transportation sectors.

Quartz-reinforced polyester composites were successfully created by compression moulding quartz after it had been impregnated with unsaturated polyester resin. When the amount of quartz in a composite is changed, a considerable shift happens in its physical, mechanical, and thermal properties. As quartz concentration rose, QPCs' flexural and compressive strengths declined. Conversely, when the filler content increased, the composites' rebound hardness dropped as a result of elastic deformation. Due to quartz's insulating qualities, the thermal characteristics of the composite dropped as the quartz content increased. As a result, the amount of quartz is crucial in assessing the physico-mechanical and thermal properties of QPCs, and more thorough research can be conducted to determine whether they are appropriate for use in various industries or not.
