Honeycomb part, manufacturing method thereof, honeycomb device, acoustic liner and aero-engine

The invention relates to the technical field of noise elimination and noise reduction, and especially relates to a honeycomb part, a manufacturing method thereof, a honeycomb device, an acoustic liner and an aero-engine. The honeycomb part comprises honeycomb walls, honeycomb cavities with polygonal cross sections are defined by the honeycomb walls, and the honeycomb walls are made of porous sound absorption materials. Different from a honeycomb wall made of a solid plate, the honeycomb wall made of the porous sound absorption material can broaden the sound absorption frequency band and improve the noise reduction effect based on the resistive effect of the porous sound absorption material. 本发明涉及消声降噪技术领域，特别涉及一种蜂窝件及其制造方法、蜂窝装置、声衬和航空发动机。本发明的蜂窝件，包括蜂窝壁，蜂窝壁围成横截面呈多边形的蜂窝腔，且蜂窝壁由多孔吸声材料制成。与由实心板制成的蜂窝壁不同，由多孔吸声材料制成的蜂窝壁，可以基于多孔吸声材料的阻性效果，拓宽吸声频带，改善降噪效果。
