A radar window for a re‐entry vehicle should process critical mechanical properties. Fused silica, BN and Si 3 N 4 ceramics are the three popular materials for such applications, but are limited in some fields for their intrinsic disadvantages. In the present study, 2.5 dimensional silica fiber reinforced Si 3 N 4 ‐BN matrix composites were prepared by a PIP method through repeated infiltration of hybrid precursor and pyrolysis at high temperature in ammonia atmosphere.
