The possibility of performing recycling process of metal-matrix composites was determined before, using only the Dupre equation. This equation allows to determine superficial conditions in the system: liquid metal (matrix)-solid reinforcement-medium, favouring the process of autogenous outflow of liquid matrix from the porous reinforcement. When using this method, the influence of the structure parameters of reinforcement preforms on examined process is difficult to assess. In order to do so, Darcy's law of flow must be used for analysis of liquid metal matrix outflow's process. Application of this law enables defining the influence of temperature and time of recycling process on matrix metal's yield.
