Purpose: The purpose of this project was to estimate the possibility of using glass carbon particleste as a reinforced component of polymer matrix in composites. Application as a basic components modified properties of phenolic resin glass carbon give a sliding composites characterized profitable tribological properties. Microscopy examination of the sliding surface together with the results of tribological investigations made it possible to conclude about friction and wear processes of the investigated composites. Design/methodology/approach: Composites on the phenolic resin as a matrix have been investigated. Apart from traditional fillers, such as graphite or brass, glassy carbon was used for the modification of the properties. Based on studies of the friction coefficient and the wear, usefulness of glassy carbon as a material reinforcing and modifying the tribological properties of sliding materials was determined. Studies of the surface structures of friction couple materials allowed the identification of the processes taking place in the upper surface after friction and wear tests, as well as the determination of wear mechanisms. Analysis of composite surface after friction give estimation of wear mechanism and forming of surface layer during friction. Findings: The results of research into mechanical and tribological properties of materials with a polymer matrix intended for work in friction couples under heavy load conditions. Practical implications: The results of that investigation confirm that glass carbon is main component deciding on the tribological properties of composites. Glassy carbon particles limited wear and thermal destruction of matrix. Modification using glassy carbon let to obtain sliding composites working at elevated temperature in extremely work condition then non modified polymer materials. Originality/value: Glassy carbon particles limited wear and thermal destruction of matrix. Modification using glassy carbon let to obtain sliding composites working at elevated temperature in extremely work condition then non modified polymer materials.
