KION defense Technologies Inc — Department of Defense SBIR Phase II: Kion Defense Technologies, Inc. (KDT) has teamed with multiple CMC producers and an engine

Description

Kion Defense Technologies, Inc. (KDT) has teamed with multiple CMC producers and an engine OEM to develop and demonstrate the effectiveness of a new, integrated matrix system for SiC-based composites for use at 1300oC (2400oF). Based on feasibility demonstration during the Phase I effort, KDT will employ its patented polysilazane resin manufacturing process to incorporate B, Al, and/or Zr heteroatoms into its ceramic precursor (CERASETTM) resins to produce various ceramic phases during CMC processing. The resulting composite microstructure will offer oxidation and corrosion protection as a result of the layered matrix structure. During Phase I these resins were shown to be compatible with several different fibers, and different CMC fabrication processes. During Phase II, KDT will advance the development of the resins, including scale-up to multi-kilogram batches, fabricate several square meters of advanced CMC's, and conduct appropriate testing in a relevant environment for this application. KDT's approach offers the multiple benefits including preceramic polymers that yield homogeneous compositions on the molecular level that are present in nanodomains, demonstrated success in fabrication of CMC's with these family of resins, and manufacturing capacity and know-how to meet the anticipated resin demands.
