Ultrahigh Temperature Ceramic‐Based Composites
This chapter describes the fabrication process and physical and mechanical properties of the zirconium diborides (ZrB2)‐ and hafnium diborides (HfB2) based composites with SiC, MoSi2, and ZrSi2 particles. The emphasis is directed toward presenting recent advances and providing an evaluation of studies for these ultrahigh temperature ceramic‐based composites. In studies that were conducted in the 1970s and earlier, densification of ZrB2‐ or HfB2‐based composites with SiC was only accomplished by hot pressing (HP). Later, spark plasma sintering (SPS), reactive sintering (RS), and pressureless sintering (PS) processes evolved as the most common densification methods. In order to improve fracture resistance or damage tolerance as well as reduce density of ZrB2‐ or HfB2‐based composites, short carbon fiber and silicon carbide fiber are being attempted to apply to the ultrahigh temperature ceramic composites. The chapter also describes the recent advances obtained in the studies on short fiber‐reinforced ZrB2‐ or HfB2‐based ceramic matrix composites.
