“…To reduce the density of ultra-high-temperature ceramics (UHTC) for aerospace applications, Kachaev et al [28] fabricated FGCMs with a gradient transition from a UHTC side to a ceramic of lower density. The high-temperature side of the five-layered FGCM was a composite of HfB 2 + SiC, while the low-density side was SiC with 7 wt-% oxide additives (Al 2 O 3 + Y 2 O 3 ).…”

“…Hypersonic and Supersonic jets generally experience aerodynamic drag and hence are subjected to extreme heat fluxes at their surfaces and therefore these spacecraft components should be able to sustain in ultra-high temperatures over 2000°C and extremely harsh and oxidizing atmospheres. Spark plasma sintered FGCMs such as SiC-HfB 2 [28], ZrB 2 -SiC-CNT [33], Cu-Al 2 O 3 [150] , ZrB 2 -ZrO 2 [263] have shown excellent thermo-mechanical characteristics, with reduced thermal residual stresses and absence of any delaminations or cracks across the sample cross-sections under highly oxidizing atmospheres. These make them very promising candidates for spacecraft body components such as nose covers, engine parts, heat exchange plates, turbine blades, etc.…”

Monolithic components are often insufficient when a combination of conflicting properties, or a variation in properties at different regions within a material is required. Functionally graded composite materials (FGCM) are a relatively new class of materials with a systematic variation of the composition, microstructure, and properties along one direction. The graded structure offers tailorable property combinations not achievable with monolithic composites and significant recent research has been carried out on their development. An effort has been made in this article to review the latest developments on bulk FGCMs since 2015. The different processing techniques used for their fabrication have been discussed, highlighting their advantages, limitations, and recent advancements pertaining to FGCM fabrication. Various physical, mechanical, and thermal properties of FGCMs have been treated separately, and wherever possible, summary plots combining data from various research articles have been developed. Finally, potential areas for directing future FGCM research have been identified.
