PARTIALLY MICRO CERAMIC MATRIX COMPOSITE ENHANCED BY DENDRITIC NANOFRACTALS

摘要

The present invention relates to ceramic matrix composites (CMC) consisting of a long fiber impregnating bonding matrix comprising a doping material consisting of a plurality of functionalized dendritic nanofractals and compounded with the composite ceramic matrix. The composite ceramic matrix, making it possible to produce technical parts, consisting of a mixture comprising at least one composite ceramic matrix, functionalized dendritic nanofractals 8 consisting of nanopatatoids 16 of 10 to 50 nanometers in diameter aggregated with each other by covalent bonds to form dendrites 13, circumscribed in a volume of 50 to 1000 nanometers in diameter, is characterized in that the functionalized dendritic nanofractals are uniformly coated with a functionalizing agent 20 arranged in a monomolecular layer 19 over their entire accessible surface 17 The present invention also relates to a method for producing the composite ceramic matrix. Application, particularly but not exclusively, in the fields of astronautics, aeronautics, marine, transport, industry, nuclear, leisure.
