| Abstract Scope |
We show that multi-material additive manufacturing enables the production of dense, advanced ceramic composites with tailored composition variation. Heterogeneous boron carbide-silicon carbide specimens with functionally graded and layered structures are produced and their mechanical properties are characterized in quasi-static and dynamic strain rate regimes.
In dynamic deformation, dumbbell geometry compression specimens exhibit a compressive strength that is and 86% higher than that of cube geometry specimens. Functionally graded dumbbells show the highest mean compressive strength of 3.96 GPa (quasi-static) and 5.11 GPa (dynamic). High-speed video analysis indicates that dumbbell geometry specimens fail due to microcrack growth and coalescence, while cubes fail by axial splitting. |
