METHOD TO MANUFACTURE THREE-LAYER PANEL FROM COMPOSITE MATERIAL Russian patent published in 2015 - IPC B32B3/12 

FIELD: construction.

SUBSTANCE: during formation of the first lining of the three-layer panel along its contour they lay out a bordering element forming an end zone and a slant zone of a honeycomb filler of the three-layer panel. The bordering element is jointly hardened with the first lining and is cut at height, excluding protrusion beyond the upper surface of the honeycomb filler. On the inner surface of the first lining they in turns install a lower adhesive film, a honeycomb filler with slants, an upper adhesive film and a non-hardened second lining, made so that its edges partially or fully cover the hardened bordering element in the slant area of the honeycomb filler, and hardening of the second panel is carried out jointly with adhesion of panel elements.

EFFECT: invention makes it possible to reduce labour intensiveness, to increase panel strength in a slant area of a honeycomb filler and to improve quality of panel appearance.
