3. Long-term mechanical behaviour

Experience shows that the quality of the reinforcement/matrix interface (e.g. the nature of the surface treatment or fiber sizing) has an exacerbated influence on long-term behavior under permanent mechanical loading (static or dynamic, alone or coupled with environmental stresses), very often much more marked than on instantaneous mechanical behavior, whatever the reinforcement/matrix system considered.
