FIELD: machine building.
SUBSTANCE: workpiece is produced by impregnation of a frame from reinforcing elements with temporary binder, then the workpiece is cooled, after the binder is hardened the obtained workpiece is machined by cutting, then the temporary binder is removed and all further stages of manufacturing process are carried out up to production of a ready part. Water is used as the temporary binder. The workpiece is hardened by freezing under temperature of 77-253 °K, then the workpiece is heated after being placed in a mould whose shape is close to the configuration of a ready part and which is fitted by grooves for temporary binder withdrawal.
EFFECT: improved quality of parts made from composite materials.
