Carbon-Phenolic Cages for High-Speed Bearings. Part 1 - Friction and Wear Response of Phenolic Composite Impregnated with a Multiply-Alkylated Cyclopentane (MAC) Lubricant and MoS2 Solid Lubricant.

摘要

This is the first part of a three-part series of reports by AFRL/PRTM to investigate carbon-phenolic bearing cages in high-speed, lightly lubricated bearings. This portion covers characterization of flat panel specimens using thermal conductivity, tensile strength, coefficient of thermal expansion measurement, and friction and wear testing in a sliding contact. The experimental data indicate that the carbon-phenolic has superior mechanical and thermal properties to the cotton-phenolic material. The friction and wear properties were similar to the cotton-phenolic baseline.
