Ceramic matrix composites are tough when the fibre-matrix bonding is properly controlled
during processing, via the use of an interphase. The interphase is either formed in situ as the …

Fiber‐reinforced ceramic composites achieve high toughness through distributed damage
mechanisms. These mechanisms are dependent on matrix cracks deflecting into fiber/matrix …

Major advances have been made during the past 2 years in the development of fiber-
reinforced oxide composites for long-life combustion components. These include …

A calcium hexaluminate (CaAl12O19, magnetoplumbite structure) sol was used to coat
alumina and yttrium‐aluminum‐garnet (YAG) single‐crystal fibers and single‐crystal …

The continuing need for materials with improved high temperature stability, oxidation
resistance, and high toughness has fueled the research and development of oxide–oxide …

Seven different aqueous or ethanolic precursors were used to continuously coat monazite
(LaPO4) on Nextel 720™ fiber tows. Immiscible liquid displacement was used to minimize …

Diphasic yttrium-aluminum garnet (Y3Al5O12, YAG) sols were made by hydrolysis of
aluminum and yttrium isopropoxides. The sols were gelled across TEM grids to make films …

The effectiveness of fugitive interfacial carbon coatings in Nextel™ 720‐based composites
was investigated. Dense (> 90%) matrix (calcium aluminosilicate, 0° and±45°) composites …

Monazite was continuously coated onto Nextel 720 fibers, using an aqueous precursor and
in‐line heat treatment at 900°–1300° C. Some experiments were repeated with alumina …

The objective of this research was to engineer a weak interfacial bond in single crystal α-
alumina (Saphikon) fiber/polycrystalline alumina matrix composites by incorporating a …
