HONEY-COM SANDWICH STRUCTURE AND MANUFACTURING METHOD THEREOF

PROBLEM TO BE SOLVED: To provide a honey-com sandwich structure and a manufacturing method thereof enabling high-density and high-accuracy temperature measurement with an optical fiber sensor in an axial direction and a direction orthogonal to the direction, that is an axial orthogonal direction.SOLUTION: As for linear portions of an optical fiber sensor (4) having curvature divided into curved portions and linear portions, the linear portions are covered their periphery with tubes (8) and embedded in an adhesion layer (2), on the other hand as for curved portions, the curved portions are housed in housing spaces (14a) of housing bodies (14) so as not to come into contact with the adhesion layer. 【課題】光ファイバセンサの軸方向とその方向と直交する軸直交方向とについて、高密度かつ高精度に温度を計測することのできるハニカムサンドイッチ構造体およびその製造方法を得る。【解決手段】屈曲部分と直線部分とに分かれるように屈曲した光ファイバセンサ（４）の直線部分については、周囲をチューブ（８）で覆われるようにし、接着層（２）の内部に埋めこむ一方、屈曲部分については、接着層と接触しないように収納体（１４）の収納スペース（１４ａ）に収納するように構成する。【選択図】図７
