Organic modified epoxy resin. Tribologic aspects

Abstract

This article presents some results of pin-on-disk tests on modified epoxy resins compared with the tribological behavior of the epoxy resin. The tribological response of materials was studied for three regimes force, sliding speed (F,v) of pin-on-disk geometry with the pin made of studied material and steel disk. All the tests were performed under thermos-vision surveillance to point out the temperature value modifications during tests and, at the end, the wear rate was evaluated for each materials. The modification of epoxy resins is an attempt to slightly change the some basic properties of the polymer such as electric conductivity but without changing their most valuable properties – thermic dimensional stability, high adhesion to almost any other material and mechanical properties. One of the major disadvantages of epoxy resins is their chemical stability that makes them almost impossible to neutralize after their life cycle. In this regard the modification of epoxies by adding small amounts of organic or inorganic compounds could lead to an increase of their environmental acceptability.
