| Description |
Near-net-shape (NNS) high alumina (alumina:silica = 96:4, in equivalent weight ratio) fibre reinforced ceramic matrix composites (CMCs) were prepared with single and bicomponent sols following sol-gel vacuum infiltration technique. The CMCs were characterized by X-ray diffraction (XRD), three-point bend test and scanning electron microscopy (SEM). Crystallization of tetragonal zirconia (t-ZrO(2)) in the composite, CZY having zirconia-yttria matrix and that of gamma alumina (gamma-Al(2)O(3)) in the composites, CAZ having alumina-zirconia matrix, CAS having alumina-silica matrix and CA having alumina matrix, enhanced the flexural strength values and pseudo-ductile character of CMCs.
