Most aerogels studied so far, however, are made from ceramic materials, such as silica, alumina and silicon carbide, and are thus very brittle. Researchers recently made aerogels from graphene (a sheet of carbon just one atom thick).
Airloys exhibit unprecedented specific energy absorption capabilities, with values as high as 190 J/g, making them superior energy absorbing materials to silicon carbide, aluminum honeyco, and polymer foams. Airloys also exhibit impressive high-strain-rate
Silicon carbide fiber reinforced silicon carbide ceramic matrix composite (SiC/SiC CMC) is the next generation of gas turbine engine hot section material, as they offer significant increase in temperature capability with the benefit of higher thermal efficiency H 2 4
Abstract Carbide-derived carbon (CDC) aerogel monoliths with very high porosity are synthesized starting from polymeric precursors. Cross-linking by platinum-alyzed hydrosilylation of polycarbosilanes followed by supercritical drying yields preceramic aerogels.

UCLA researchers and collaborators at eight other research institutions have created an extremely light, very durable ceramic aerogel. The material could be used for appliions like insulating spacecraft because it can withstand the intense heat and severe temperature changes that space missions endure.
Silicon carbide is formed in two ways, reaction bonding and sintering. Each forming method greatly affects the end microstructure. Reaction bonded SiC is made by infiltrating compacts made of mixtures of SiC and carbon with liquid silicon.
