Hybrid Composite Systems

Seamless integration between PSC-10 and UHT-21 materials systems via co-fabrication. Only put the refractory where it’s needed

Co-fabrication of PSC-10 and UHT-21 to save weight and cost without loss of performance.

Both our PSC-10 and UHT-21 use the same base pre-preg components, allowing for seamless integration of the two materials systems beginning at the lamination stage. Parts are co-processed from layup through cure, ceramitization, and final machining ensuring that there is no distinct interface between the two materials systems in the final composite component.

Key Features:

A common prepreg system enables co-lamination and curing of PSC-10 and UHT-21 in the preform state. The materials systems are combined and co-processed as one component through our entire fabrication process.

Benefit to Customer

The refractory-modified pre-preg is only placed in the hot sections where necessary for the component to have greater thermal resistance. The rest of the component is the PSC-10 system which saves both weight and cost relative to a fully refractory-modified component with no appreciable difference to the mechanical properties of the system.
