Novel aluminum-wood combined component and manufacturing method

Abstract

The invention discloses a novel aluminum-wood combined component and a manufacturing method, and belongs to the technical field of combined structures. the novel aluminum-wood combined componen comprises an aluminum alloy hollow pipe, at least four stiffening ribs and wood, wherein the rift grain direction of the wood arranged in the aluminum alloy hollow pipe is consistent with the length direction of the aluminum alloy hollow pipe, namely the extrusion direction of an aluminum pipe, rib grooves corresponding to the stiffening ribs in position and number are uniformly formed in the outer surface of the wood towards the center, each stiffening rib is correspondingly arranged in one rib groove, and the stiffening ribs are fixedly connected to the inner wall of the aluminum alloy hollow pipe. In the novel aluminum-wood combined component and the manufacturing method, the aluminum pipe is wrapped around the wood, so that the wood is in a three-dimensional pressed state, the aluminum pipe is restrained by the wood and the stiffening ribs, the instability of the aluminum pipe is delayed, the defects of the aluminum alloy and the wood which are independently used are overcome, the novel aluminum-wood combined component can be used as an axis compression component, an eccentric compression component or a bending component to be widely applied to light structures, offshore structures, structures in corrosive environments, structures such as factory buildings.

Description

technical field [0001] The invention belongs to the technical field of composite structures, in particular to a novel aluminum-wood composite component and a manufacturing method thereof. Background technique [0002] Composite structures are gradually favored by structural engineers because they can take advantage of the respective advantages of materials. As an emerging structural material, aluminum alloy has the advantages of light weight, high strength, durability, environmental protection, and beautiful appearance, but its high cost and instability characteristics (the elastic modulus of aluminum alloy is low, only 1 / 3 of that of steel) ) limits its wide application in the structural field. Aluminum alloy components often use closed cross-sections (such as: round aluminum tubes, square aluminum tubes, rectangular aluminum tubes, etc.), combining aluminum alloy tubes with other filling materials can significantly improve the mechanical properties of components and solve...

Problems solved by technology

However, the friction between aluminum and wood in the aluminum-wood composite section is small and the use of adhesives may make the components difficult to recycle. It is difficult for ordinary aluminum-wood composite components to achieve good cooperation under all working conditions only by friction ability, this issue becomes an important challenge limiting the application of this composite section
