METHOD FOR MANUFACTURING A HONEYCOMB FILLER FROM POLYMER COMPOSITE MATERIALS Russian patent published in 2022 - IPC B32B3/12 

FIELD: composite materials.

SUBSTANCE: invention relates to a method for manufacturing a honeycomb filler from polymer composite materials for multilayer panels and shells. The invention can be used for the manufacture of products with high specific mechanical characteristics in aviation and rocket and space technology. A method for manufacturing a honeycomb filler from polymer composite materials, including laying the reinforcing material into a mold by alternating the material and forming rods to a given thickness, then the material is cured and the rods are dismantled. What is new in the invention is that the dry reinforcing material is uniformly impregnated with a binder under pressure after being placed in a sealed mold, the inner surface of which repeats the outer surface of the honeycomb filler. After solidification, the molds are disassembled, the forming rods are removed and the honeycomb filler is ready for use in multilayer panels and shells.

EFFECT: presented method makes it possible to produce honeycomb fillers of various heights, with various shapes and sizes of cells.
