System for manufacturing ceramic composite aerospace materials
Aerospace / Composite Materials
Develop new methods for making ceramic matrix composites. These materials are advantageous for applications in gas turbines and aircraft engines because they are lighter than the commonly used nickel superalloys and have better resistance to high temperatures. Engines containing such components may be more thermodynamically efficient and produce fewer emissions from an environmental point of view.
Develop and manufacture a press to make ceramic/ceramic-fiber composites as part of a collaborative aerospace industry/university research project. It involves applying pressure to a mixture of water and ceramic powder, and filtering this liquid through a porous ceramic fibre membrane. The system is equipped with a robotic controller interfaced with a computer to perform the acquisition of experimental data.
- Control flow mode and piston advance speed
- Precise control of electric cylinder at very low speeds
- Sealing for an extremely abrasive fluid
This equipment accurately measures the permeability of various porous media. It’s very important to define the operating parameters of the infiltration processes to produce the ceramic composite matrix. In addition, the Darcy cell piston can also be used as a high-precision injector for moulding parts of more complex geometries.
