Friction and Wear of Blends of high-temperature Thermoplastics

PEEK/PEI and PEKEKK/PEI-blends are investigated, to determine the thermal, mechanical and tribological properties. In addition to the unfilled blends the PEEK/PEI-blends are filled with carbon fibre, PTFE and graphite to improve the tribological behavior. It is shown, how the blends are compounded and processed. The PEEK and PEI are homogeneous miscible, proved by thermoanalytical investigations. The glass-transition temperature increases with increasing PEI-contents. The crystallization oft orocessed blends is low. A special annealing program is developed to increase crystallization for increasing wear resistance. The mechanical properties of the blends are characterized depending on the influence of the temperature and depending on the PEI-contents. A pin-on-disc-machine is developed to investigate friction and wear. The temperature of the air and the steel-disc can be regulated until 400 °C. For the blends the optimum roughness of the steel-disc at room temperature is determined. At optimum roughness the influence of the temperature and the PEI contents is studied. These results are compared with the mechanical properties of the blends. The material costs for the blends but also the mechanical and tribological properties and maximum sliding surface temperature decrease with increasing the PEI-contents.Up 20 % PEI-contents the decrease of thes properties are is not significant.
