Purpose: The purpose of the paper is to show and compare of modern method composite materials with aluminium alloy matrix reinforced by Ti(C,N) particles manufacturing. Design/methodology/approach: Powders of the starting materials were wet mixed in the laboratory vibratory ball mill to obtain the uniform distribution of the reinforcement particles in the matrix. The mixed powders were then dried in the air. The components were initially compacted at cold state in a die with the diameter of Ø 26 mm in the laboratory vertical unidirectional press - with a capacity of 350 kN. The selected compacting load was sufficient to obtain prepregs which would not crumble and at the same time would not be deformed too much, which would also have the adverse effect on their quality, as the excessive air pressure in the closed pores causes breaking the prepreg up when it is taken out from the die. The obtained PM compacts were heated to a temperature of 480-500°C and finally extruded - with the extrusion pressure of 500 kN. Findings: The received results show the possibility of obtaining the new composite materials with required structure joining positive properties composite materials components. Practical implications: Tested composite materials can be applied among the others in automotive industry but it requires additional researches. Originality/value: It was demonstrated structure of the extruded composite materials with the EN AW-Al Cu4Mg1(A) alloy matrix may be formed by the dispersion hardening with the Ti(C,N) particles in various portions and by the precipitation hardening of the matrix.
