Abstract

Abstract: Abrasion is the most common and aggressive type of wear in industrial practice. As a solution we can replace original metal components by up-to-date engineering polymer composites. However, it is not so easy to choose from the wide choice of polymers (mechanical properties, price, etc.), therefore we investigated two polymer composite groups (PA 6 and PEEK) with different mechanical properties and price. The main objective of our study was to compare the tribological properties of different PA 6 and PEEK composites, based on the results of different laboratory friction model tests. Also we wanted to investigate the effect of different additives against abrasive surface. The tests were carrying out with different load (11,5N and 23N) relations. We used emery-(grinder)-cloth to produce the abrasion mating surfaces in a special test rig. The friction tests were prepared in pin on plane (band) model system, where the friction force and the wear were continuously measured. Our present work is connected to a research project, which aims to map the tribological features of different polymer composites.
