Document Type and Number:
WIPO Patent Application WO/2013/069202
Kind Code:
A1
Abstract:
[Problem] In a stacked material based on a honeycomb material, in a bond between the base honeycomb material with two facing materials which sandwich the honeycomb material, flat members with high rigidity and high flatness precision are bonded with a honeycomb member which is striated and not completely flat and level, preventing strong bonding. [Solution] Provided is a honeycomb panel stacked body in which a stacked body is formed from a sound dampening face, a sound dampening layer, and a reflecting face, the sound dampening face is formed from a foaming body, and the sound dampening layer is formed from the honeycomb material and a layer in which the spaces are filled with a hard foam material, and comprises a structure in which a leading end part of the honeycomb material of the sound dampening layer is coated with a bonding agent, and the leading end part is pressed against the sound dampening face and made to eat into the foaming body, bonding thereto. A soundproofing face which is on the opposite side of the honeycomb material is formed from a foaming body, and has a bonding structure in which one face which contacts the honeycomb material is coated with the bonding agent, and the reverse leading end parts of the cell partitions of the honeycomb material are pressed on the soundproofing face and made to eat into the foaming body, one face of which is coated with the bonding agent.
