New liquid processing of oxide/oxide 3D wowen ceramic matrix composites

In this work, a novel process named Flexible Injection Process ( FIP ) was developed to manufacture near‐net shape oxide/oxide composites reinforced with 3D interlock fibers. This process uses a flexible membrane to apply pressure to promote transverse impregnation of the fibrous reinforcement by a slurry charged with sub‐micron ceramic particles. Due to the through‐thickness filtration and compaction, FIP process is much faster than typical...
