METHOD OF MANUFACTURE OF THE CELLULAR FILLER Russian patent published in 2006 - IPC B32B3/12 

FIELD: furniture industry; construction industry; ship-building industry; aircraft industry; space-rocket industry; methods of manufacture of cellular fillers.

SUBSTANCE: the invention is pertaining to the method of manufacture of cellular fillers for the three-layer panels and shells, in particular, made out of the glass-fiber cloth and may be used in different industries: furniture industry, construction industry, ship-building industry, aircraft industry, space-rocket industry. The technical problem of the invention is to increase the interlaminar strength of the cellular blocks along the glue bands at manufacture of the bulky glass-cellular blocks. The method includes: application of the glue bands on the canvas of the material in the longitudinal direction; the canvases of the material cutting into billets in the direction perpendicular to glue bands; assembly of a cellular package by stacking the billets with a shift of each billet in respect to another one by a half of the pitch of the glue bands; agglutination of the billets of the cellular package in compliance with the given mode and production of the cellular block by stretching the cellular package, impregnation of the cellular block with a polymeric binding with its following curing. At that before stretching conduct a thermostabilization of the free hanging cellular package within 4-5 hours at the temperature exceeding the temperature of polymerization of the glue by 10-30°C.

EFFECT: the invention ensures an increased interlaminar strength along the glue bands of the bulky glass-cellular blocks.
