FIELD: machine building.
SUBSTANCE: invention relates to the field of machine building and can be used in the construction of automotive, aviation, rocket and space technology. Grid shell from composite materials 1 contains bearing frame 2 corresponding to its profile in the form of a rib-cellular structure with end frames 3. Structure is formed by layers of systems of overlapping high-modulus filaments, held together by a cured polymeric binder. End frames 3 are made of metal and contain on its outer surface converging and diverging grooves 4. Grooves 4 have at least one annular belt of intersections 5 and are graded in their cross-section and along the length of the arrangement under the ribs of an end part of the bearing frame 2 in which the latter are located.
EFFECT: technical result consists in expanding the range of applicability of shells made from composite materials by increasing the strength, rigidity and reliability of the structure.
