M-857 Continuous Alumina Fiber
Description
M-857 is a continuous polycrystalline ceramic fiber grade for heat-resistant textiles and oxide ceramic composites. Sol-gel precursor processing provides continuous filaments that can be woven, braided or incorporated into composite structures.
CHARACTERISTICS
- Continuous inorganic filaments
- Oxidation resistance
- High modulus and low thermal expansion
- Grade-specific oxide composition
