About this Symposium

Meeting MS&T24: Materials Science & Technology
Symposium Advanced Manufacturing of High Temperature Ceramics and Composites: Processing, Characterization and Testing
Sponsorship ACerS Basic Science Division

Scope The symposium focuses on fabrication of high and ultra-high temperature ceramics (UHTCs) and fiber-reinforced ceramic composites using advanced methods such as additive manufacturing (AM) and advanced fiber placement methods. Manufacturing of ceramics and ceramic composites requires considerable research and development to meet requirements, specifications, and provide consistent properties. The characterization and testing of matrix and binder materials, layering effects, interlaminar shear, preforming structural stability, densification, shape complexity of ceramic components affect the processing and properties of final components. Also, it is important to test higher temperature thermal and mechanical properties for AM fabricated materials, as well as their ablation and corrosion response at high temperatures and in high enthalpy flows, in plasmas, under irradiation conditions, and in other extreme environments where these materials are expected to be applied in the future.

Proposed topic areas relating to manufacture of high and ultra-high temperature ceramics and composites include, but are not limited to:

·  AM methods such as binder jetting, stereolithography, selective laser melting, extrusion based AM, and fused deposition modeling

·  Enhancements to commercial AM systems and materials

·   New and novel manufacturing methods for ceramics and UHTCs

·  In-situ process monitoring for enhanced defect and microstructural control (e.g. fiber alignment and/or placement, powder packing, etc.)

·  Process modeling for enhanced understanding of structure-property-processing relationships

·  Unique and novel strategies to overcome inherent densification issues

· High temperature thermomechanical characterization (e.g. oxyacytelyne torch, laser heating, plasma exposure, high-temperature mechanical testing, etc.)
