Uniform Fiber Dispersion Preforming for CMC Turbine Components (1000-734) Navy SBIR FY2005.2 Sol No.: Navy SBIR FY2005.2 Topic No.: N05-096 Topic Title: Uniform Fiber Dispersion Preforming for CMC Turbine Components (1000-734) Proposal No.: N052-096-0046 Firm: TRITON SYSTEMS, INC. 200 TURNPIKE ROAD Chelmsford, Massachusetts 01824 Contact: Thomas Carroll Phone: (978) 250-4200 Web Site: www.tritonsys.com Abstract: Triton Systems Inc. (Triton) proposes to demonstrate a solution to practical limitations in available fiber sizes and weave constructions that inhibit effective reinforcement of tight corner and bend radii prevalent in gas turbine hot section components. Through development of silicon carbide fiber molding compounds, engine hardware will have continuous reinforcements that enable reinforcement of thin wall fine geometric details. During the Phase I effort, Triton will define and evaluate molding compound formulations that fulfill mechanical performance requirements while permitting reinforcement of small design features intrinsic to turbine engine hardware. Evaluation will also include densification process development to yield low porosity CMC's. The ability to efficiently reinforce a turbine vane design feature will be included. Projections will be established for manufacturing costs based upon information used and developed in the Phase I. In a Phase II award, Triton will begin the Phase I Option by obtaining high temperature material properties. Also, constituent materials and fabrication processes will be documented to expedite a swift transition towards production. The Phase II activity will select a demonstration component with our engine partner to be fabricated, coated and tested in a realistic engine environment. Benefits: Successful development of cost effective and reliable hot section CMC components is an enabling technology for turbine engines to operate cleaner and more efficiently. Potential commercial applications include aircraft propulsion and electric power generation as well as ceramic diesel and gasoline internal combustion engines. Return
