Tribological and Physicomechanical Properties of Oil-Filled, Phenilon-Based Composites

Resumo

This paper concerns the development of oil-filled, heat-resistant aromatic polyamide Phenilon C-2-based composites with high physicomechanical characteristics, an advantage that can withstand loads of up to 25 MPa and operating temperatures of up to 250°C in friction units. When producing oil-filled, Phenilon C-2-based nanocomposites with 300–320°C molding temperature, the choice of oils is limited and depends on their ability to maintain lubricating properties at high temperatures. The physicomechanical and tribological test results using different friction machines prove oil filling’s high efficiency in creating a stable lubricating film on a tribocontact and in improving the tribological properties of polymer composites. Research results helped outline the range of the most promising hybrid fillers for Phenilon C-2-based polymer composites and lubricants for oil filling, which contribute to the formation of a long-lasting lubricating film on a tribocontact. The combination of the experimental studies and a scientifically based approach to predicting the properties of polymer nanocomposites makes possible expedited development of new materials with high target characteristics. The technology of the production and use of these oil-filled polymers refers to nontraditional areas of plastic processing; however, the world statistics of production and consumption of polymeric friction and wear inhibitors shows that these materials are one of the most promising ways to reduce operating losses.
