Abstract : This program is concerned with exploratory development work on new and improved solid lubricant materials and processes for requirements within a wide range of environmental conditions. More than 80 self- lubricating compacts and composites have been prepared utilizing partially carbonized phenolic resins (CPR) as the matrix. A wide range of materials, including sulfides, oxides, nitrides, carbides, fluorides, metals, and glass or graphite fibers have been found to be compatible within the CPR SYSTEM. Most of the lubricant evaluation work has been done on carbonized phenolic resin (CPR) samples to aid in the further development of these materials through friction and wear evaluation. The three- pellet tester, the oscillatory slider, and the journal bearing test device were used for these evaluations. In addition, the flexural strength and elastic modulus were determined for two different types of cast CPR composites. A series of friction and wear tests was conducted on polyimide bonded molybdenum disulfide and fluorinated graphite solid lubricant films using the Falex and dual rub-shoe test devices.
