Abstract:

The state-of-the-art clutch plate for the lift systems is made of carbon-carbon composites and is challenged to meet future life and frictional requirements. This clutch is very similar in configuration to an aircraft brake, but operates at significantly higher speeds approximately 8500 rpm. Generally speaking, the clutch plates are required to withstand a high shear load, resist sliding wear, withstand high peak temperatures, and have high static and dynamic friction coefficients to minimize slippage. The clutch plates also need high thermal capacity to dissipate large amounts of frictional energy introduced at a very high rate during engagement. A new family of nano-reinforced ceramic matrix composites (CMC) is proposed as the next generation frictional materials for improved wear and frictional performance. Although the frictional performance data of CMC are very limited, there are enough evidences indicating CMC or C-SiC in specific may ameliorate many deficiencies associated with their C-C counterpart. Under this proposed effort, carefully selected CMC candidates will be fabricated using production-ready materials and processes. Candidate materials will be tested on dynamometer under realistic conditions. Performance trends will be established and used for further optimization.
