One of the advantages of composites is that an engineer creates the material and structure at the same time. This makes it possible to achieve maximum efficiency in the use of material, but at the same time leads to the need to develop new approaches to assessing the strength reliability of the material in each specific application. This work is devoted to the study of the strength of layered fibrous composite materials used, in particular, for fan blades of aircraft engines. For this purpose, a virtual experiment was carried out to optimize the macrostructure of the material. The advantage of this approach is obtaining reliable information about the strength and reliability of structural elements without costly field tests, based on a developed mathematical model of a material sample and a virtual experiment, using modern methods of strength analysis.
