HONEYCOMB PANEL MANUFACTURING METHOD Russian patent published in 2021 - IPC B32B37/00 

FIELD: astronautics.

SUBSTANCE: invention relates to space engineering and can be used in production of thermostatically controlled honeycomb panels, on the surface of which instruments, equipment and interfaces are installed. Objective, which is solved by the claimed invention, is creation of a method for manufacturing of a honeycomb panel, which improves quality of the obtained panel due to exclusion of introduced process internal stresses during polymerisation of the honeycomb panel. Set task is solved due to the fact that method for manufacturing of honeycomb panel, which includes connection of elements of assembly - skin with cellular filler and parts of saturation - by gluing, placing the assembly installed on the process plate through the backing sheet into the chamber furnace and creating in the process of gluing for the required time of the required gluing temperature and pressure of the cladding pressing to the honeycomb filler and saturation parts. Method is implemented so that when the assembly is installed on the process plate for gluing through the backing sheet, a second backing sheet is installed on the free surface of the panel. Backing sheets are made interchangeable; the material of the backing sheet has a coefficient of linear temperature expansion (CLTE) equal to or as close as possible to CLTE of the skin material. To reduce friction during heating in the process of gluing, a layer of antifriction material in the form of a film or a lubricant, for example, a fluoroplastic film, is placed between the lower backing sheet and the process plate.

EFFECT: technical result of honeycomb panel manufacturing is provision of preset geometrical accuracy at manufacturing of honeycomb panels.
