Purpose: The paper presents the investigation results of tribological properties of composites with an aluminium matrix, which contain various types of reinforcing particles. Design/methodology/approach: Tribological tests were carried out on composites containing SiC or Al2O3reinforcing particles (homophase composites) and composites reinforced with a mixture of SiC or Al2O3particles with an additive of glass carbon (heterophase composites) as a frictional properties modifier. Findings: The results of friction and wear coefficients’ investigation allowed the determination of how the addition of glass carbon can influence tribological characteristics. The replacement of the part of the reinforcement with glass carbon particles led to a reduction of both the friction and wear coefficients of heterophase composites and of the grey cast iron cooperating with them. Practical implications: The results obtained allow us to claim that it is possible to change the tribological properties of composites as a result of using reinforcing particles with various physical and mechanical characteristics. Originality/value: The utilization of heterophase reinforcement enables, to a large extent, the broadening of the possibilities of designing the tribological properties of friction couples.
