AI Technical Summary
Technical Problem
The existing chemical vapor infiltration (CVI) process for fabricating ceramic matrix composite (CMC) components is hindered by surface pores filling before the interior, leading to non-uniform density and infiltration issues.
Method used
A ceramic matrix component with a fibrous core having greater porosity than the surrounding preform, optionally featuring ceramic foam, sacrificial fibers, and cooling passages, is fabricated using CVI, allowing improved access and uniform infiltration.
Benefits of technology
The approach enhances infiltration, reduces stress, and results in CMC components with more uniform density and improved structural integrity, addressing the challenges of surface pore filling and non-uniform density.
