Materials and Applications of Inorganic Fibers

Thistable(and Table 19.2below) shows that the major competitor to CVD SiC is carbon as both fibers have similar properties and are in the same cost bracket. Another competitor is boron but it is expensive and may eventually be replaced by silicon carbide. 

Material Processing Main Characteristics Typical Applications 

Glass Melt blowing and spinning High strength Low modulus Low temperature Low cost Insulation Reinforced plastics 

Oxides Melt spinning Sol-gel Medium strength Good oxidation resistance High cost Ceramic composites High-temp insulation Filtration 

Boron CVD High strength High modulus High cost Plastic and metal composites
