Abstract: | Polyesterimide (PEI) and phenol formaldehyde (PF) samples were synthesized, and composites of the two polymers, as well as composites with carbon, were prepared. Using a pinon-disc machine, the friction and wear properties of the following samples were studied in the load range of two to eight bars: - Phenolformaldehyde vs. steel
- Phenol formaldehyde cured with hexamethylenetetramine vs. steel
- Polyesterimide vs steel
- Polyesterimide and carbon composite vs steel
- Phenol formaldehyde vs polyesterimide
- Phenol formaldehyde and polyesterimide composite vs. phenol formaldehyde
- Phenol formaldehyde and polyesterimide composite vs. steel.
The data obtained from these experiments were compared with literature data on poly(tetrafluoroethylene) and nylon, conventionally used for tribological applications. It is seen that, in terms of thermal stability, friction, and wear, PEI and PF are promising for tribological applications. |
