| Abstract Scope |
This study investigates the influence of silica composition and particle size distribution on the mechanical behavior of additively manufactured (AM) ceramics under quasi-static and dynamic loading. A custom-formulated silica-based slurry has been developed for DLP printing of three lattice architectures: simple cubic, body-centered cubic, and gyroid. By varying silica content and particle size, we examined their effects on printability, densification, and resulting microstructures. Mechanical performance was evaluated through quasi-static compression and Split Hopkinson Pressure Bar (SHPB) tests. Results reveal that finer and bimodal particle distributions improve packing density and reduce porosity, leading to enhanced strength and energy absorption. Additionally, gyroid structures exhibited superior dynamic response due to their continuous surfaces and stress distribution characteristics. This work highlights the interplay between compositional design and structural geometry in AM ceramics, offering insights for optimizing mechanical performance for impact-resistant applications. |
