Title:
METHOD FOR PRODUCING BORON NITRIDE FIBER AND RESULTANT FIBER
Document Type and Number:
Japanese Patent JP2003286616
Kind Code:
A
Abstract:
To provide a continuous and weavable high-purity boron nitride fiber having a high level of performances maintainable even under natural aging and obtainable from a polyborylborazine type precursor polymer with a diameter suitable for use in composite materials, and to provide a method for producing the fiber.
The boron nitride fiber is produced by using a borylborazine precursor represented by the formula [(NHR)2B(NR)]3B3N3H3 [wherein, R denotes hydrogen atom or a 1-30C alkyl, a 1-30C cycloalkyl or a 1-30C aryl group].
