Description

Joining techniques such as welding, brazing, riveting and screwing are used by industry all over the world on a daily basis. A further
method of joining has also proven to be highly successful: adhesive bonding. Adhesive bonding technology has an extremely broad range
of applications. And it is difficult to imagine a product - in the home, in industry, in transportation, or anywhere else for that matter - that
does not use adhesives or sealants in some manner. The book focuses on the methodology used for fabricating and testing adhesive and bonded joint specimens. The text covers a wide range of test methods that are used in the field of adhesives, providing vital information for dealing with the range of adhesive properties that are of interest to the adhesive community. With contributions from many experts in the field, the entire breadth of industrial laboratory examples, utilizing different best practice techniques are discussed. The core concept of the book is to provide essential information vital for producing and characterizing adhesives and adhesively bonded joints.
