Reinforcement/matrix bond - Behavior of composites

The first two parts of this dossier define and highlight the practical importance of the reinforcement/matrix bond in composite materials, and then present the various experimental methods for characterizing this bond. and theoretical approaches to modeling of this interfacial zone (or interphase). The aim of this third section is to illustrate the influence of the reinforcement/matrix bond on the behavior of industrial composites. The consequences of a change in the interface on instantaneous and long-term mechanical behavior (dynamic fatigue, creep, stress-cracking), aging (particularly in hostile environments), fire resistance and biodegradability are highlighted on the basis of various examples (experimental results obtained on test specimens and industrial parts, depending on the case, for composites with thermoplastic or thermosetting matrices, reinforced with fillers or fibers of various kinds, either chopped or continuous, possibly recycled).
