FIELD: process engineering.
SUBSTANCE: invention relates to production of articles from composite materials, particularly, shell for structural components, namely, to assembly units of solid-propellant rocket engines. Proposed method comprises applying initial material impregnated with binder on shaping mandrel, locating said mandrel in hydraulic pressure vessel with elastic diaphragm, hardening material package at pressure and temperature, curing at 150-165 °C and package cooling down. Note here that, immediately after curing, initial material package is first cooled on elastic diaphragm side to 140-145°C, then cooling is performed on mandrel side and continued on both sides to 50-60°C. Now, pressure is dropped to perform forced cooling and, then, natural cooling to room temperature.
EFFECT: higher quality due to perfection of material structure.
