Composite Metal Bonding Structure With Sleeve-Sealed Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Composite material structural members with different materials exhibit bonding lines that lead to poor sealing performance and corrosion due to material differences, affecting the appearance and functionality of the composite material.
Innovation Solution
A composite material structure is created by bonding two metal members of different materials, where a sleeve is formed by hot melting on the second metal member to cover the bonding line between them, enhancing sealing performance by blocking the gap and preventing corrosion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two different metal members are bonded together to form a composite material structure, then the structural diversity and functional performance are improved, but a bonding line appears at the interface which causes poor sealing performance and corrosion resistance
Solution Approach 1:
A sleeve component is introduced as an intermediary element between the first and second metal members. The sleeve covers the bonding line at the interface, acting as a mediator that prevents direct exposure of the bonding line to the external environment, thereby improving sealing performance and corrosion resistance while maintaining the composite structure's functional diversity
Solution Approach 2:
The solution employs a composite structure consisting of the original two metal members plus an additional sleeve component. This multi-material composite approach combines the advantages of different metals while adding a protective layer that addresses the sealing and corrosion issues at the bonding interface
2Adaptability or versatility
If two different metal members are bonded together to form a composite material structure, then the structural diversity and functional performance are improved, but the bonding line is prone to corrosion due to contact with the external environment
Solution Approach 1:
The sleeve serves as a protective intermediary that isolates the bonding line from the external environment. By covering the bonding line, the sleeve prevents direct contact between the bonding interface and corrosive environmental factors, thereby improving corrosion resistance while preserving the composite structure's diversity
Solution Approach 2:
The bonding line, which initially represents a weakness and vulnerability to corrosion, is transformed into a protected feature. The sleeve converts the harmful exposure of the bonding line into a beneficial sealed interface, where the bonding line remains structurally necessary but is now protected from environmental damage
3Adaptability or versatility
If a bonding line is formed between different metal members, then the composite structure is created, but the bonding line affects the appearance of the composite material structural member
Solution Approach 1:
The sleeve acts as a cosmetic intermediary that covers the bonding line, improving the appearance of the composite structure. The sleeve provides a continuous, uniform surface that hides the visual discontinuity of the bonding line, thereby enhancing aesthetic appearance while maintaining the composite structure's functional integrity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The method effectively seals the bonding line, improving the sealing performance and preventing corrosion, thereby enhancing the structural integrity and appearance of the composite material.
Implementation Method 1
a sleeve is formed on the main body by hot melting, the sleeve defines a second hole therein and surrounds the second hole, and the sleeve extends into the first hole for covering the bonding line

AI summary
A composite material structure includes a first metal member and a second metal member bonding to the first metal member. A bonding surface is formed therebetween. A first hole is through the first metal member. A circular bonding line is formed at a junction of a wall of the first hole and the bonding surface. A sleeve protrudes from the second metal member into the first hole, and covers the bonding line. A groove indents from the first metal member. The groove has a bottom surface located in the same plane with a top surface of the sleeve. A processing method of the composite material structure is also provided. The sleeve covers the bonding line between the first metal member and the second metal member, which allows the composite material structure to provide an improved sealing performance.
