TEXTILE PREFORMS SHEATHED IN A BORON NITRIDE COATING, COMPOSITES INCORPORATING THEM AND THEIR PREPARATION |
| 摘要 |
<p>The present invention provides:fiber preforms sheathed in a boron nitride coating, said coating (generated on said previously-prepared fiber preforms) having a structure that is original: microporous and granular;thermostructural composite materials in which the reinforcing fabric is constituted by said fiber preforms; andmethods of preparing said fiber preforms and said thermostructural composite materials, respectively.The composites of the invention have their fiber preforms, based on fibers (F), sheathed in an original interphase (IBN) and embedded in the densification matrix (M).</p> |
