Strength properties of fiber composites depend upon fiber location in them. The fiber location in composite is defined by the conditions of its production, for instance, by a type of sheet semi-product used. In spite of the significance of the factor mentioned above the mathematical methods describing the peculiarities of the structure of composites manufactured under different conditions are absent. That is why, the creation of simulators allowing the manifestation of an actual structure of fiber composites is of actual interest At the production of fiber composites made of different types of sheet semi-products the peculiarities of fiber location are defined by their random displacements from the initial ordered position in a semi-product. For the creation of structure simulators of such composites the approaches can be used which are contained in the simulation. In this work there is supposed an algorithm which allows reproducing the peculiarities of the structure of composites made of different types of sheet semi-products with the aid of simulation. The investigations carried out show that with the aid of the algorithm developed the structure close to an actual structure can be imitated. It is confirmed by experimental data. The fiber composite structure models formed with the aid of the simulation can be an initial base for the strength properties prognostication of material taking into account its structure.
