FIELD: process engineering.
SUBSTANCE: invention relates to production of parts from composite materials, namely, rotation shells of structural components. Production of variable-wall thickness shells comprises forming multilayer package of material by tape coiling, tape being pre-impregnated with thermosetting binder of carbon fabric onto rigid mandrel made up of variable-diametre rotation shell. First, inner walls are coiled to diametre making 0.8-0.9 of the package OD. Note here that coiling in wall thickening zone is made under pressure of 1-2 kgf/cm2 and temperature of 60-90°C. Then, outer tape layers are coiled with carbon fabric acting on the tape. Prior to application of carbon fabric, the package is subjected to same temperature. Note here that coiling in wall thickening zone is made under pressure and temperature on the distance from end face of 0.6-0.65 of part length along the part axis.
EFFECT: higher quality of variable wall thickness rotation shells from composite materials.
