What is your opinion of laminate and fibrous monolith ceramics?

[zmat]

I have been investigating ceramics for high thermal loading and have come accross papers describing thermal shock resistance for laminate and fibrous monolith ceramics (from Clegg and Halloran). They seem to give good results, but I am unsure about there use in structural applications. Does anyone know if it is "proven technology"?

Yes, but it is the cost that gets it into trouble.
