Our present work is connected to a broad tribology research project with
different polymer composites on PA6, POM, PET and PEEK matrix and targeted
to create a detailed map of tribological features. Measuring the hardness and
surface energy of the tribology tested materials gave some new approach about
friction results. The small-scale laboratory friction tests were carried out with an
alternating (reciprocating) cylinder/plate model system, which is able to measure
the dynamic and the static friction force on-line during the sliding process. This
special test system opens up new possibilities for understanding the phenomena
of friction. In the article we give a short introduction from the surface energy
and the shore D hardness test methods also.
The research results plot a connection between the surface (polar and
adhesion components) energy and the friction (static and dynamic) behaviour.
Furthermore the experienced difference between the static and dynamic friction
coefficients and its time function will offer a new approach during evaluation of
the stick-slip behaviour of PA6 and PEEK composite materials.
