High strength aluminum nitride fibers and composites and processes for the preparation thereof

摘要

Shaped articles of polycrystalline aluminum nitride are disclosed having a tensile strength of at least about 100 Kpsi. The shaped articles are preferably fibers. Composites of polycrystalline AlN fibers in a matrix of organic or inorganic polymer, metal, glass or ceramic are also disclosed herein. The process for the preparation of polycrystalline aluminum nitride fibers is covered.
