Summary

Particulate sols and solutions were used to apply carbon-oxide multilayered coatings, mixed alumina-carbon coatings, and monazite (LaPO4) coatings to various SiC fiber tows and 3M Nextel 720™ fibers. These coatings can degrade fiber strength, sometimes to such an extent that the coated fibers cannot be spooled. Carbon coatings protect fibers from strength degradation, but oxide coatings adhere poorly to carbon coatings. Coating characteristics that may affect fiber strength are discussed.
