Title:
FLUID FLOW-RECTIFICATION MEMBER
Document Type and Number:
Japanese Patent JP2016141582
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a fluid flow-rectification member of a structure in which the weight increase is suppressed and which has a sufficient surface strength.SOLUTION: A fluid flow-rectification member 10A includes a cylindrical portion 20A surrounding the central axis CL; the cylindrical portion 20A includes a supporting member composed of an inner-layer ceramic fiber layer 22 and an outermost-surface side ceramic fiber layer 22, and a ceramic matrix covering the supporting member; and in which, the number of a unit ceramic fiber 40 in a strand 214 forming an outermost side ceramic fiber layer 222 of the fluid flow-rectification member 10A is set greater than the number of a unit ceramic fiber 40 of a strand 215 forming an inner layer ceramic fiber layer 223 which is an inner layer of the outermost side ceramic fiber layer 222; thereby, the increase in weight can be suppressed and the strength of the surface of the fluid flow-rectification member 10A can be increased.SELECTED DRAWING: Figure 4
