Abstract: After almost twenty years Aircraft Division of Military Technical Institute has worked on the project that involves the primary structure made of composite materials. The ideas about some other similar projects exist. The most important part of the design of composite materials structures is determination of the strength of the structure. This paper discusses the modern directions as well as certain problems in the strength calculation of the structures made of composite materials.
