ABSTRACT:
The aim of the present invention is a process for manufacturing boron nitride fibers, in particular continuous boron nitride fibers with good mechanical properties, which may be used for producing ceramic composite materials such as BN/BN composites, thermostructural parts or antenna radomes.It provides and uses a precursor polymer of formula (I) below:in which n is a whole number, R1and R2, identical or different, represent independently an alkyl group, and R3represents an amino group, a hydrogen atom, an alkyl, a cycloalkyl or a boryl.
