Oxide based ceramic matrix composites

摘要

A method of making a ceramic matrix composites (CMC) having superior properties at high temperatures. The CMC can include a sol gel mixture mixed or blended metal oxide particles. The sol-gel mixture can be an aqueous colloidal suspension of a metal oxide, preferably from about 10 wt % to about 25 wt % of the metal oxide, containing a metal oxide such as alumina (Al₂O₃), silica (SiO₂) or alumina-coated silica. The mixture can be infiltrated into a ceramic fiber, gelled, dried and sintered to form the CMC of the present teachings.
