NDE of Ceramic Matrix Composite Material

Filed under: Recent Projects.

Description:

Ceramic Matrix Composites (CMCs) fulfill advanced propulsion system requirements for high temperature, very high performance material. The manufacturing process for S-200 CMC requires repeated measurement of porosity. Evisive Scan non-contact measurement and real time presentation of porosity data permits much shorter production time than conventional alternative measurement methods. This is evaluated by the US Air Force as a key element for 75X improvement in production cost.

Summary:

Under SBIR AF07-105 NDE of CMC’s Phase I and Phase II contracts, Evisive is developing the testing apparatus for in-process measurement of porosity for manufacturing of CMC material.  The Evisive Scan microwave interference scan voltage is correlated to CMC porosity with very high repeatability and precision.

Results:

Ongoing SBIR work has successfully demonstrated correlation of Evisive Scan voltage and S-200 CMC material porosity. Under the project, Evisive is completing equipment design specification and fabrication.  The process will be used in manufacturing of CMC components for the F-35 Joint Strike Fighter Program.
