Studium modifikace materiálu frikčních kompozitů při třecím procesu

Abstract

This thesis studies the modification of materials in laboratory-prepared samples of friction composites with various types of fibrous materials for reinforcement of the matrix. The practical part focuses on the analysis of the wear material, which escapes into the environment as suspended portion, which can enter into the airways of the human organism and make a health risk, or as a sediment of the wear material, which contributes to soil contamination. At the same time the thesis brings information about a modification of the composite and reactions during the friction processes. The evaluation was done by optical and electron microscopy, X-ray diffraction and X-ray fluorescence analysis.
