FIELD: turbo-machines.
SUBSTANCE: group of inventions relates to axial turbine machine outer housing from composite material. Housing from composite material for axial turbine machine contains circular wall, containing matrix and woven fibrous stiffening element (40). Depending on its thickness stiffening element (40) comprises two outer layers (48) and one central layer (50), arranged between layers (48). Layers (48, 50) contain woven fibres passing in circular wall axial direction, and woven fibres, passing along circular wall circumference. At least one of layers (48) has difference in ratio between axial woven fibers and circular woven fibers. Axial woven fibers make largest part of woven fibers.
EFFECT: group of inventions is aimed at improvement of housing composite material annular wall mechanical resistance in case of contact with rotor blades.
