METHOD OF HONEYCOMB PRODUCTION Russian patent published in 2008 - IPC B32B3/12 C08J5/24 B32B17/04 

FIELD: technological processes.

SUBSTANCE: method includes application of adhesive strips in longitudinal direction on initial material cloth, its cutting into stocks in direction that is perpendicular to adhesive strips, honeycomb packet assembly from stocks by means of packing with displacement of every stock in relation to adhesive strips adjacent by half of pitch, adhesion of honeycomb packet stocks according to preset mode, stretching of honeycomb packet and its impregnation with polymer binder, drying of impregnated honeycomb packet on air with further hardening of polymer binder, at that as initial material glass tissue is used, after honeycomb packet impregnation with polymer binder its excess is removed by free flowing to the moment of sharp reduction of flowing binder amount, stretched honeycomb packet is turned over by 180°C, and surplus of polymer binder flows into its cells from the top end of honeycomb packet for the time equal to 1/3 of the time spent for previous flowing, once again stretched honeycomb packet is turned over by 180°C, and surplus of polymer binder flows from the other end of honeycomb packet in its cells for 1 minute, stretched packet is turned over by 90°C, while channels of cells are located horizontally, and drying of impregnated honeycomb packet is performed for at least 3 hours at room temperature by means of stretched honeycomb packet cells blowing with organised air flow directed to exhaust ventilation.

EFFECT: method provides high interlayer strength and eliminates exfoliation in adhesive strips; uniform strength and density in the whole volume of honeycomb and provision of air drying process intensity.
