    <description descriptionType="Abstract">&lt;p&gt;A series of high-density ceramic composites with carbon fibre content between 40 and 65% and ultra-refractory ceramic matrix was produced by slurry infiltration and hot pressing. The matrix consisted of ZrB2&amp;ndash;10 vol% SiC or ZrB2&amp;ndash;40 vol% SiC ceramic mixtures. Water&amp;ndash;based and polymer&amp;ndash;based routes were tested to analyse the effects on microstructure, mechanical properties and oxidation resistance at 1650 &amp;deg;C in air. Changing the process and/or the processing parameters was found to affect the final composition, the amount of residual porosity, the matrix/fibre adhesion. Composites with nearly fully dense matrix and optimized infiltration of fibre preforms were found to possess the highest strength (240 MPa) and oxidation resistance. Composites with a weak interface and higher porosity in the matrix showed higher toughness (up to 12 MPa m0.5) but were more prone to oxidation and erosion.&amp;nbsp;&lt;/p&gt;</description>
