Abstract


The Monte Carlo method to define quantitative characteristics of fiber intersections in the fiber rubcon structure taking into account the defined sizes of the samples was shown, adapted and applied in the paper. Dependence graphs of the amount of areas with dimensions smaller than the diameter of the allowable heterogeneity on the fiber percentage were presented. The studies were aimed at creating a material with the desired properties. The prerequisites to the study of this issue was the unsolved problem of the arrangement, distribution and sizes of congenital defects in the fiber rubcon structure. An analytical and mathematical justification of the optimal reinforcement ratio of rubcon with various types of fibers was obtained, a comparison of the results with experimental data was made. The results of the studies can be useful in the design stage of dispersion-reinforced composites, presuppose possible micro-defects content in the structure of materials, affecting the stress-strain characteristics of the material. Fracture pattern of samples depending on the type of the fiber used and its percentage was determined. It was proved that fiber rubcon meets the technical requirements for materials, operating in corrosive media by its stress-strain parameters and crack resistance, determined under the action of short-term compressive loads.
