Abstract
Acrylic resin is widely used in fields such as aerospace, military, coatings, and electronic equipment due to its excellent physical and chemical properties. The mechanical properties of its polymer composite materials are influenced by various factors such as component volume fractions, types, and treatment methods. In this paper, the mechanical properties of particle-reinforced acrylic composites and the factors affecting them are investigated. The effect patterns of the contents of glass beads, quartz sand, and heavy calcium carbonate on the tensile, bending, and compressive properties of the polymer composites were experimentally investigated. Combined with the digital image correlation (DIC) to observe the dynamic damage images of the specimens, the full strain field information was analyzed and the local strain distribution was studied. A finite element model of polymer composite materials was established, and the numerical simulation results were consistent with the experimental results. The progressive damage and failure process of the composite materials was analyzed. This research result can guide the experimental design and application of particle reinforced acrylic composite materials.
