Ageing testing - Adhesive bonding aging test

The ageing of an adhesive bond is defined as the change in the quality of the adhesive bonding as a function of time and external factors that promote the change.

During the life and use of an adhesive bonding, it supports external effects like mechanical, physical and chemical that produces the phenomenon of ageing, the main objective of ageing tests is to accelerate and simulate these effects in order to observe and predict the behavior of the adhesive bond and propose solutions if necessary.

The effects that produce the ageing phenomenon in adhesives and in adhesives joints are:

During the design phase, it has to be mentioned all the external factors that can affect the adhesive bond and can produce ageing in the joint, in order to perform ageing tests with combination of external factors, to predict the future behavior of the adhesive joint.

Among the most widely used aging testing we can include:

ageing testing

Once ageing tests has done, we proceed to inspect or breaking the specimen using destructive methods or non-destructive methods, based on the information to be obtained, in order to get the conclusions of the behavior of the adhesive joint.

There are several rules which specify the conditions of ageing and the type of test performed, we can cite:
