Design and Manufacture of a Device to Determine Shear Force in Adhesive in the Interpretation of Metal-To-Metal Bonding Under ASTM D1002-10

Abstract

This study focuses on the design and manufacture of a specialized device to measure the shear force in adhesive joints, with emphasis on the interpretation of the metal-metal joint. The practical application of the device involves the bonding of a square tubular profile (PTR) to an aluminum specimen using an epoxy adhesive specific to steel joints.

The design of the device focuses on creating a system capable of applying an axial load and measuring the shear force required to separate the PTR and the aluminum specimen. The geometry of the parts to be joined, the load distribution and the ability to reproduce realistic force application conditions are considered.

The manufacture of the device is carried out with precise techniques to ensure the accuracy and reliability of the results. Strong and durable materials are used to ensure the structural integrity of the device during multiple tests.

The experimental procedure involves the preparation of the bonding surfaces, the application of a steel-specific epoxy adhesive and the attachment of the PTR to the aluminum specimen. The device is then used to measure the cutting force required to separate the parts.

The results obtained are analyzed to determine the effectiveness of the adhesive in metal-to-metal bonding. Factors such as adhesive strength, cohesion between metal surfaces and the influence of geometry on shear force are considered.
