VULCANISER FOR SOLIDIFICATION OF MULTI-LAYER COMPONENTS OF AIRCRAFT Russian patent published in 2010 - IPC B29C43/52 B29C70/46 B29C43/18 B29C70/68 

FIELD: machine building.

SUBSTANCE: vulcaniser for energy-saving solidification of multi-layer components 6 for aircrafts consists of open and mechanically sufficiently durable core 7 with layers of coating 8, 9 applied on one side or on both sides. Multi-layer component 6 is enclosed between hold-down piston 1, support bed 2 and side walls 3, 4 of the vulcaniser forming essentially closed internal space 5. At least one layer of coating 8, 9 and/or core 7 contains solidificated thermo-reactive plastic material. By means of transport facility 20 heated air 16 is let through core 7 of multi-layer component 6 in the closed circuit of heated air and ensures energy-saving interior solidification of multi-layer component. Heated air 16 has temperature controlled by means of heater 22. If there is implemented an open circuit of heated air, there is facilitated recuperation of heat by means of heat exchanger 28. Specified parametres of solidification inside core 7 of multilayer component 6, particularly pressure of solidification P, as well as temperature of solidification T can be regulated depending of system of resins used for fabrication of multi-layer component 6 by means of the vulcaniser.

EFFECT: reduced consumption of energy at solidification of component in autoclave.
