Mechanical behaviour of SiC (Hi-Nicalon) fibre-reinforced Si(3)N(4) matrix composites under monotonic and fatigue tensile loading
Fully dense SiC/Si(3)N(4) were fabricated by slurry infiltration followed by hot-pressing. Two types of pyrolytic carbon coatings were deposited at the fibre-matrix interface and resulted in clearly different interfacial properties thus mechanical behaviour. Composite �A� exhibited a higher monotonic tensile strength (700 MPa) and a better fatigue limit (550 MPa) compared to composite �B� (630 MPa and 450 MPa, respectively). Interfacial properties were established through hysteresis loop modelling.
