PROBLEM TO BE SOLVED: To provide a honeycomb sandwich panel capable of inhibiting detachment due to in/out pressure difference and suppressing strength reduction.SOLUTION: A honeycomb sandwich panel 10 constituted by sandwiching a honeycomb core 11 with a honeycomb structure in which a plurality of cells 21 with a hollow shape opens at both end surfaces between a pair of plates 12 and 13, has an air hole 23 communicating neighboring cells 21 with each other, an air escape pore 13a penetrating an inner face plate 13 in a panel thickness direction and communicating with the cell 21, and a seal member 14 consisting of a material arranged in the inner surface plate 13 so that the air escape pore 13a is closed from an outside of the panel thickness direction and extending and contracting in the panel thickness direction when in/out pressure difference between a pressure in the cell 21 and a pressure of ambient air is generated.SELECTED DRAWING: Figure 2
【課題】内外圧力差に起因した剥離を防止して、強度低下を抑えることができるハニカムサンドイッチパネルを提供する。【解決手段】中空状をなす複数のセル21が両端面に開口するハニカム構造のハニカムコア11を、一対の板材12,13間に挟み込むようにして構成されるハニカムサンドイッチパネル10において、隣接したセル21同士を連通させる通気孔23と、内面板13をパネル厚さ方向に貫通し、セル21と連通する空気逃げ孔13aと、空気逃げ孔13aをパネル厚さ方向外側から密閉するように内面板13に設けられ、セル21内の圧力と外気の圧力との間における内外圧力差の発生に伴って、パネル厚さ方向に伸縮する材料からなるシール部材14とを備える。【選択図】図2
