Abstract Scope |
Additive manufacturing of Ultra High Temperature Ceramics (UHTC) provide a number of unique solutions in supporting high performance materials capabilities for armor and hypersonic engine applications. The advantage of 3D printing offers a distinct ability of producing complex parts with reduced configuration for machinability. As the architecture requirements become more stringent, parts become more challenging to produce, due to increasing size and higher resolution based on application. This suggest that the properties of the pre-sintered green body, play an enormous role in quality of the final part. In this work, we investigate a number of strengthening additives to improve the mechanical and structural properties of our preceramic polymer green bodies. Our previous work has shown that we can achieve high densification of our unique polymer based ceramic formulation. With green body strengthening, we will show that we may provide facile approaches to some of the challenges 3D printed ceramics face. |
