Morphological and Mechanical Characterization of Ceramic Composite Materials
Fiber-reinforced CVD-ceramic composites, C-SiC, have been tested in three point bending for three orientations of the notch prior to the applied stress. For the two main orientations, load-unloading sequences have been performed to investigate the rupture parameters using the Sakai and al’s method. The very good mechanical behaviour of these materials are found to be due to the energy dissipative effect of the reinforcement. For the weaker orientation an empirical method is proposed to measure the compliance at any point of the P(h) curve.
