Sound Absorption and Load Bearing Integrated Structure and Preparation Method Thereof

Disclosed is a sound absorption and load bearing integrated structure and a preparation method thereof. The sound absorption and load bearing integrated structure comprises of a first connecting node and a holed hollow rod connected to the first connecting node. The first connecting node is of a solid structure, and the connecting portion of the first connecting node and the holed hollow rod is in smooth transition by means of a cambered surface. The first connecting node and the holed hollow rod form a sound absorption unit. The holed hollow rod of one sound absorption unit extends forwards from an axial direction of the first connecting node, and extends to be connected to a first connecting node of another sound absorption unit, or extends to be intersected with a holed hollow rod of another sound absorption unit so as to form a second connecting node.
