Title: Manufacture of flexible honeycomb core
Inventor: MATSUOKA KATSUNORI
IPC: B32B7/02
Filed: 1988-08-03
Abstract: PURPOSE:To realize high quality flexible honeycomb core by a method wherein corrugated sheet materials with nearly trapezoidal wave-like folds are piled up, joined with amorphous soldering material and finally extended. CONSTITUTION:Each corrugated sheet material 7, in which nearly trapezoidal wave-like folds are produced by continuously bending, is corrugated by passing a flat sheet material through a corrugating device. Next, on the surface at the ridge or trough of the corrugated sheet material 7, amorphous soldering material 8 is applied at every other ridge or trough and provisionally fixed to the material 7 by spot-welding or adhesive bonding. Next, fluxing agent is used as stopping material 9 and applied to the surface, onto which no amorphous soldering material 8 is provided, of the corrugated sheet material 7. And several layers of the corrugated sheet materials, on each of which the amorphous soldering material 8 and the stopping material 9 are annexed, are piled up vertically. The respective piled up corrugated sheet materials 7 are pressed vertically and, after that, mutually and locally joined by thermally fused amorphous soldering material 8. Next, the joined corrugated sheet materials 7 are placed on a plate bed and extended by moving pins, each of which is inserted in a cell 6 at one of both side ends, with a moving mechanism, resulting in letting tensile force apply to the corrugated sheet materials 7 so as to set apart their non-joined parts through deformation and separation into the predetermined shape. As a result, a special shape honeycomb core is lightly and easily obtained.
