Durability

Durability defines the period of use of a structure. For composite matrices the term expected lifetime or pot life is used.

The minimum durability of a structure or component is generally imposed by the project owner or engineer. Products which have a minimum lifetime higher than imposed must be selected.

The durability of a composite structure will depend on the environment in which it is located, the changes to its load pattern over time and how it has been made and the materials used. In traditional environments, a composite structure may reasonably be assumed to have a durability of more than 10 years.
