METHOD FOR CURING OF PART OF POLYMERIC COMPOSITE MATERIALS Russian patent published in 2005 - IPC

FIELD: moulding of parts, applicable for manufacture of complicated large-sized aircraft engines of polymeric composite materials by vacuum-autoclave moulding.

SUBSTANCE: the method comprises: arrangement in a chamber of a mould with a casing with a part of polymeric composite materials positioned on its moulding surface, and the outer surface of the casing rests on the charging table. The temperature in the chamber is changed with the aid of the main electric heater, and additional electric heaters with temperature-sensitive elements are used for provision of a uniform heating of the part of polymeric composite materials to the curing temperature. The additional electric heaters are installed on the outer surface of the mould casing for the time of curing. The temperature-sensitive elements are positioned between the mould casing and the additional heaters. The temperature of the additional electric heaters is maintained by 5 to 15°C higher than the temperature in the autoclave until the temperature of curing of the part of polymeric composite materials is settled in the chamber.

EFFECT: enhanced quality of the curing process, as well as simplified design of the moulds used for manufacture of parts of polymeric composite materials.
