Creating composites with better properties at the same time components of the material components, is the most current trends in Materials. Composites with inter-linked structure by itself nature (eg, bone, shell chitin, etc.) have a unique combination of properties, combining the flexibility and durability of components. We note that 10 years ago was not known approaches to the creation of interpenetrating ceramic composites. method of producing such composites in each case is unique, tied to the properties of individual components. For example, interpenetrating composites of superhard nitrides or borides with copper having a high wear resistance and electrical conductivity, obtained by spark-plasma sintering (thermal sintering in electric fields with the formation of plasma at the contacts of conductive particles). In rare cases, interpenetrating structures arise during spinodal decomposition of solid solutions in a narrow range of compositions, for example, cooling of the alloy is almost immiscible Be and Al. Creating interpenetrating composites from various polymers, metals may be in liquid or melt at a specific organization of polymerization processes (cooling). Interpenetrating 3-dimensional composites to maximize combine both the properties of both materials, often in the composition, far from the percolation threshold in irregular (random) composites. Modern fabrics are 2-dimensional analogue of interpenetrating composites.
