Microstructural Analysis of Granular Metal-Ceramic Composite Materials of Matrix Type M.A.
The cluster structure of microphotographs of the metal-ceramic composite materials surface samples has been analyzed.
In this regard, the study of the mechanical and micro-structural characteristics of the materials obtained is important and relevant for predicting the physical and chemical properties of these materials.
Of great interest is the study of the fractal properties of materials and the cluster analysis of microphotographs.

The advantages of composites reinforced by bi-axial and multi-axial knitted fabrics were discussed and the applications of such advanced materials were briefly presented.
Multi-axial knitted materials are mainly used to make airplane wing-covering, frontal edge and the rim of the empennage, fuselage panels, rudder's front edge and engine panel.

Another accepted method of the composite materials manufacturing is the in situ synthesis method.
A considerable part of such materials are composite materials based on aluminum or its alloys with a unique combination of physical and mechanical properties [1, 2].
