DoubleSolder joints are widely used due to their simple manufacturing process, suitability for bonding thin adhesive materials, and slot connections. Among them, the internal adhesive layer...
Stresses (including shear, tensile, uneven tearing, and peel forces) are primarily applied in the direction of strength.
Above, therefore, splicing joints are a commonly used type of joint. However, the tensile loads formed by splicing joints are prone to...
The adhesive layer is subjected to shearing stress, and the simple lap joint design is prone to misalignment, causing the shearing force to no longer be aligned in a straight line.
At this point, the aforementioned factors can lead to splitting at the end of the joint, severely compromising its performance.
Should be avoided during design. In summary, improvements to typical lap joint designs should include the following points.
Reengineered connectors to align the load of the bonded materials on a single line.
Thicken the adhesive material near the bonding surface and increase its strength.
Edge surfaces are made softer to enhance adhesion and reduce peel stress.
Using dovetail joint design is an easy method to adjust loads. Provide a pressure application gauge.
Surface, when the loads on both sides of the joint are unbalanced, a double lap joint design should be adopted to balance the two sides.
Load. This type of connector performs better than flat connectors, as the splitting stress at the end of the connector is reduced under the action of the load.
Below, the tenon face can match the material to be bonded.
