  • Process for manufacturing boron nitride fibers from borylborazines
    Patent number: 6967179
    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, R1 and R2, identical or different, represent independently an alkyl group, and R3 represents an amino group, a hydrogen atom, an alkyl, a cycloalkyl or a boryl.

  • Process for the production of a multidirectional textile preform and piece of composite material incorporating said preform
    Publication number: 20040244859
    Abstract: A process for the production of a textile preform from interlaced filaments or sections of filaments, using a support (16) of a shape appropriate to the preform, on which are applied superposed layers of filaments or sections of filaments crossed in at least two directions, the layers being interconnected by filaments or sections of filaments which pass through them, and the filaments or sections being stretched or held on the support (16) by pins (18). The method further includes the step of reimplantation of the pins (18) by offsetting them, so as to avoid the concentration of defects inherent in the use of pins.

  • Method for making boron nitride fibers from aminoborazines
    Patent number: 6774074
    Abstract: The invention concerns a method for making boron nitride fibers by drawing a polymer precursor and treating with ceramics the polymer fibers obtained by drawing. The invention is characterized in that the precursor polymer is obtained by thermal polymerization of a borazine of formula (I) wherein: R1, R3, R4 and R5, identical or different, represent an alkyl, cycloalkyl or aryl group; and R2 represents a hydrogen atom or an alkyl, cycloalkyl or aryl group.
