PROBLEM TO BE SOLVED: To provide a fluid flow-rectification member of a structure that will not be broken by a pressure exerted by the fluid even in places where the cross-sectional radius suddenly changes.SOLUTION: A fluid flow-rectification member 10A includes a cylindrical portion 20A surrounding the central axis CL; the cylindrical portion 20A includes a first conical portion 41 having a first busbar angle α1 which is an angle of the side surface relative to the central axis CL formed when the conical shape is cut in a plane containing the central axis CL in the first conical portion 41, and a second conical portion 42 which is continuous to the first conical portion 41 as well as having a second busbar angle α2 larger than the first busbar angle; the first conical portion 41 and second conical portion 42 include a supporting member made of a ceramic fiber layer 22, and a ceramic matrix covering the supporting member; and in which, the second fiber-to-fiber density of the outermost side ceramic fiber layer 222B in the second conical portion 42 having a larger busbar angle is set higher than the first fiber-to-fiber density of the outermost side ceramic fiber layer 222A in the first conical portion 41; and thereby, the fluid flow-rectification member 10A of a structure that will not be broken by a pressure exerted by the fluid, is obtained.SELECTED DRAWING: Figure 3
【課題】断面半径が急変する箇所においても流体から受ける圧力によって破損することのない構造の流体用整流部材を提供する。【解決手段】流体用整流部材１０Ａは、中心軸ＣＬを包囲する筒状部２０Ａを有する。筒状部２０Ａは、第１円錐部４１と、第１円錐部４１に連続するとともに第１円錐部４１における中心軸ＣＬを含む平面で円錐形状を切断した際の、中心軸ＣＬに対する側面の角度である第１母線角度α１よりも大きな第２母線角度α２を有する第２円錐部４２とを有する。第１円錐部４１および第２円錐部４２は、セラミック繊維層２２からなる支持材と、支持材を覆うセラミックマトリックスとを有する。そして、第１円錐部４１における最外側セラミック繊維層２２２Ａの第１繊維間密度よりも、母線角度が大きな第２円錐部４２における最外側セラミック繊維層２２２Ｂの第２繊維間密度を高く設定した。これにより、流体から受ける圧力によって破損することのない構造の流体用整流部材１０Ａが得られる。【選択図】図３
