Researchers at Purdue University have developed a technique for the manufacture of ceramic matrix composites that automates fiber orientation and placement. This technique provides a mold-less approach to producing complex shapes and allows greater control of local and global microstructure and thermal history of the precursor material when compared to traditional manufacturing techniques while also reducing tooling and manufacturing costs. This technology has uses in a wide range of composite applications, particularly those for which withstanding high temperatures is critical. Examples include brake discs, rocket engines, heat shields, and thermal protection systems for hypersonic vehicles and structures.

- Easier to manufacture complex part geometries
- Greater control over local and global microstructure
- Lower tooling/manufacturing costs
- Can be integrated into existing additive manufacturing processes using polymer-reinforced fibers

- Ceramic brake discs
- Heat shields and thermal protection solutions
- Rocket engines
- Furnace chamber and component fabrication

Technology Validation:
This technology has been validated through small batch manufacturing and pyrolysis of complex shaped 3D printed parts including a hollow cylinder and converging-diverging nozzle.
