Mechanical Behaviour of Hi-Nicalon Fibre-Reinforced Si3N4 Matrix Composites under Monotonic and Fatigue Tensile Loading
Fully dense SiC / Si3N4 were fabricated by slurry infiltration followed by hot-pressing. Two types of pyrolytic carbon coating were deposited at the fibre-matrix interface and resulted in clearly different interfacial properties thus mechanical behaviour . Composite "A" showed a higher monotonic tensile strenght (700 MPa) and a better fatigue limit (550 MPa) compared to composite "B" (620 MPa and 450 MPa respectively). Interfacial properties were assessed by modelling of hysteresis loops.
