In this work we present novel ultra-high-temperature ceramics matrix composites (UHTCMCs) for aerospace featuring optimized fiber/matrix interfaces and fibers distribution. The microstructures were produced by electrophoretic deposition of ZrB2 on unidirectional carbon fibers followed by slurry infiltration and consolidation by hot pressing. Different matrix and coating compositions were tested. The microstructure and properties are discussed. Typical values of flexural strength and fracture toughness are 330 MPa and 14 MPa m1/2, respectively.
