Properties of composites made through saturation of ceramic reinforcement preforms with liquid metal are the cause of growing use of these materials. Taking increasing requirements regarding environment protection into consideration, already during design of such materials one should think of a way of their recycling at the end of life. The recycling of these materials is conducted by separation of components. Determining optimal superficial conditions of a recycling system: liquid metal matrix – reinforcement preform – medium enables automatic course of the recycling process, but does not guarantee high yield of metal. With identical superficial conditions of the recycling system and different structure of reinforcement preforms significant differences in metal yield can be obtained. Identification of a type of a capillary present in reinforcement preforms may allow to determine, already during stage of material design, which types of composites will undergo the recycling process better and for which types one has to accept decreased yield of matrix metal. This identification can be done on the basis of an analysis of results obtained during examination conducted with mercury porosimetry, comparing acquired hysteresis graphs with model graphs proposed by de Boer for adsorbent analysis. Considering the analysis of image of structure of examined reinforcement preforms makes the identification process easier and faster.
