Fiber Materials

Available from Free Form Fibers

Material Key Benefit
Silicon carbide (SiC) Ideal combination of strength to weight ratio and oxidation resistance at high temperature. Stoichiometric (pure SiC) form is most valuable as properties are very sensitive to oxygen content.
Boron carbide (BC) Hardness second only to diamond, excellent abrasive material.
Amorphous boron (a-B) Highest specific-strength known, short of single wall carbon nanotubes.
Tungsten carbide (WC) Very high hardness, excellent impact erosion resistance, high temperature capable, platinum substitute for catalyst, substrate for diamond.
Boron nitride (BN) Primary interphase coatings for ceramic matrix Pyrolytic and nano-porous carbon composites. (available as coating only)

Potential Materials from Free Form Fibers Refractories

Material Key Benefit
Hafnium carbide (HfC) / Tantalum carbide (TaC) The two highest temperature structural materials known to man.
Titanium diboride (TiB2) Very hard, stable ceramic at high temperature and a superconductor at low temperature.
Hafnium diboride (HfB2) Very high temperature material with excellent strength and hardness.
Tungsten disulfide (WS2) High corrosion resistant material at high temperature.
Molybdenum carbide (MoC) Very hard, high density, high temperature ceramic with good resistance to oxidation.
