ADVANCED CERAMIC FIBERS, L.L.C. — Department of Defense SBIR Phase I: N141-074

Description

Advanced Ceramic Fibers, LLC has developed a transformational enabling fiber technology for use in UHT turbine engines - alpha silicon carbide/carbon based fibers - with capability above Navys goal of 2700 F. Our turbine engine OEM and aerospace team members are excited about the MC/C fibers for use in more robust/durable CMCs with higher temperature capability for turbine engines (TE). ACFs has experience in EBCs and trap sealants for TE static and rotating components to 4000 F. ACFs in-house technical team is highly experienced in development of fibers and CMCs for turbine engines and highly qualified to develop the physics and thermo-chemical-based models for MC/C fiber reinforced UHT ceramic composites with improved environmental robustness to mitigate effects of moisture-induced volatilization or corrosive deposits, or matrix cracking in high temperature gas turbine hot section components. Physics modeling will include both steady and kinetic models using Density Functional Theory (initial stages of chemical reactions) with non-first principles MD simulations for longer exposure times. IN Phase I, we will fabricate MC/C test coupons for use in CMC matrices. These materials will lead the way in Phase II to new TE designs.
