Abstract
The influence of fiber/matrix interactions on the mechanical behavior of ceramic matrix composites is examined on glass matrix composites and mainly on composites made by chemical vapor infiltration (CVI) of a fiber preform by a SiC matrix. Then the relationships between interfaces and features of the stress-strain behavior are highlighted on microcomposite specimens using experimental data and predictions from a model based upon fracture statistics. Finally the incidence of interfaces on fracture toughness is discussed on 2D SiC/SiC composites. It is shown that rather strong interfaces provide both strong and tough 2D woven fiber reinforced composites.
