Title (EN) HONEYCOMB SANDWICH STRUCTURE AND METHOD FOR MANUFACTURING SAME
(FR) STRUCTURE SANDWICH EN NID D'ABEILLES ET SON PROCÉDÉ DE FABRICATION
(JA) ハニカムサンドイッチ構造体及びその製造方法
Abstract:
(EN) Provided are a honeycomb sandwich structure and a method for manufacturing the same, with which moisture absorption deformation can be substantially reduced. A honeycomb sandwich structure (1) is provided with: a honeycomb core (3) having a recessed part (6b) in a mesh of a carbon fiber fabric; a pair of skins; a resin layer (8b) filling a part of the recessed part (6b); and a water shielding film (7b) covering a surface exposed region of a portion constituted by the resin layer (8b) and the honeycomb core (3). The recessed part (6b) has an unfilled portion (61b) which is a portion on the opening side of the recessed part (6b) that is not filled with the resin layer (8b).
(FR) L'invention concerne une structure sandwich en nid d'abeilles et son procédé de fabrication, avec laquelle une déformation par absorption d'humidité peut être sensiblement réduite. Une structure sandwich en nid d'abeilles (1) est pourvue : d'un noyau en nid d'abeilles (3) ayant une partie évidée (6b) dans une maille d'un tissu de fibre de carbone ; d'une paire de revêtements ; d'une couche de résine (8b) remplissant une partie de la partie évidée (6b) ; et d'un film de protection contre l'eau (7b) recouvrant une région exposée de surface d'une partie constituée par la couche de résine (8b) et le noyau en nid d'abeilles (3). La partie évidée (6b) comporte une partie non remplie (61b) qui est une partie sur le côté ouverture de la partie évidée (6b) qui n'est pas remplie par la couche de résine (8b).
(JA) 吸湿変形を十分に抑制できるハニカムサンドイッチ構造体及びその製造方法を提供する。ハニカムサンドイッチ構造体(1)は、炭素繊維織物の目の部分に窪み部(6b)を有するハニカムコア(3)と、一対の表皮と、窪み部(6b)の一部を充填する樹脂層(8b)と、樹脂層(8b)とハニカムコア(3)とから構成される部分の表面露出領域を覆う遮水膜(7b)とを備え、窪み部(6b)には、窪み部(6b)の開口側の部分であって、かつ樹脂層(8b)により充填されていない部分である非充填部分(61b)が設けられる。
