H8: Ceramic integration and additive manufacturing technologies

HTCMC9_750x120_new

 

Traditional methods for fabricating ceramics and ceramic matrix composites are limited by manufacturability of large parts and complex shapes. In addition, component production can be time consuming and costly. Novel fabrication processes in additive manufacturing, joining, and integration of ceramics and ceramic matrix composites can overcome these limitations. Ceramic integration and additive manufacturing technologies increasingly enable fabrication and utilization of components for hightemperature structural applications, including those in energy, environment, transportation, and aerospace. Joining processes allow combination of simpler parts to form large structures or complicated shapes. Integration processes allow incorporation of ceramic and ceramic matrix composite components with metal-based systems. Joining and integration approaches include adhesives, brazing, glass sealing, diffusion bonding, transient liquid phase bonding, and reactive processes.

 

Additive manufacturing processes allow innovative complex part fabrication, client customization, rapid prototyping, and distributed manufacturing. In additive manufacturing approaches, threedimensional models are designed minutely according to theoretical concepts in computer graphic applications, and two-dimensional cross sections are created by automatic slicing operations. Twodimensional layers are built up through powder bed processes that use high resolution laser beams or binder jetting to form solid planes, or through layer stacking processes, paste extrusion, fused deposition, and curing of photoreactive resins.
