Adhesive Bonding: Introduction

Adhesive Bonding Illustration This section intends to show one more aspect of joining aluminium heatless, adhesive bonding. The view on joining techniques can be used to assess specific advantages and disadvantages of adhesive bonding which is a further key technology for the binding of joined aluminium components. Joining is a key issue in the development and manufacturing of products and building structures. To make optimum choices among the numerous joining methods engineers have to define the requirements of the joint with respect to

  • the part’s materials combinations; aluminium, mixed metals, organic, coated/uncoated
  • design; thick/thin, accessability, etc.
  • functionality; strength, durability, removability, etc.
  • characteristics of the joining method

Important factors for using adhesive bonding are:

  • no structural or geometrical change due to thermal impact (“cold” connection process)
  • wide range of possible combinations, including coated, other metallic, organic, or non-organic materials (e.g. plastics with Aluminium)
  • possible combination of adhesive bonding with mechanical or thermal joining techniques
  • high exploitation of material properties because of surface-related force transfer

This section covers the following topics:

Basic knowledge of design and/or some practical experience in design, manufacturing and assembly techniques will be useful.

Learning Outcomes for this Section

After completing this section, you should be able to:

  • characterise the shown joining method
  • assess special advantages and disadvantages of different joining methods
  • select a suitable joining method for different demands
  • define the joining area for a particular joining technique
  • learn about the combination of different joining techiques - hybrid joining

Pre-Requisites

Before starting, it is important that you are familiar with the following terms: yield stress; formability; material locking; frictional connection; positive locking;
