The nonoxide ceramic matrix composites (CMC), such as carbon fiber/carbon (C f /C), were developed in the 1970s as lightweight structures for aerospace applications. The mechanical properties of Al 2 O 3 can be improved by produc-ing ceramic matrix composites with different ceramic and metal particle additives such as zirconia (ZrO 2 ) and metal phase (Ni, Cr. Yu et al [ 22 ] studied the thermal properties and ablative resistance of SR prepared using aluminum silicate ceramic and calcium silicate fibres as porcelain fillers. Most modern matrix composite materials employ a variety of carbon nanofillers to improve their mechanical, electrical, and functional properties. This article also gives the comprehensive review of general characteristics and mechanical properties of silicon-based composites used in a. Al-based, Mg-based, Ti-based alloys,. R.
