The quality and the quantity assessment of the structure of the AlSi13Cu2 alloy matrix composites reinforced with carbon fibre in the amount of 5, 10, or 15 vol. percent has been presented. Due to the poor wettability of carbon fibre by molten AlSi alloy and the low castability of the examined composites, the Ni-covered fibre with 0.25 [mikro]m thick Ni layer has been used and the pressure casting technology has been employed. The chemical interaction between Ni layer and the molten AlSi alloy has been estimated in the thermodynamic aspect using the Thermo-Calc calculation packet as well as performing the microstructural investigations by means of transmission electron microscope. Simulations of solidifying have been carried out and the phase composition of the metal matrix has been determined. Microstructural examinations have proved that the total dissolving of the Ni layer occurs under the conditions of composite production and the phases of the Al3Ni type (Fe and Cu dopped) arise. These phases occur in the form of independent precipitates in the whole volume of matrix as well as the ones locally grouped around the carbon fibres.
