(1) Hybrid organic matrix composites

We are developing the testing methodologies to measure mechanical properties of hybrid organic-inorganic matrix composites that are made from the functionally graded architecture of carbon fiber, kevlar and polymer resin. This composite is designed primarily for the next generation of blade fan casings of Pratt & Whitney aircraft engine.

(2) Refractory metal alloys for high temperature applications

Turbine blade of aircraft engine is often exposed to the high temperature environment. Thus, it is important to retain superior mechanical properties even at elevated temperature. So far, single crystalline Ni-based superalloys have been used in commercial airplanes, but there have also been a lot of efforts to use a different materials for turbine blade applications. Refractory metals would naturally good candidate due to their high melting temperature and high strength.
