| Résumé : |
To cope with the extreme temperatures seen by missiles and missile parts during flight, MBDA, in patnership with the University of Birmingham, Surface Transforms plc, DSTL, and the DGA, and funded under the MCM ITP programme, developed high- and ultra-high-temperature ceramic (UHTC) technologies. These technologies are eiher based on a carbon/carbon fibre-reinforced hafnium diboride (HfB2) material originally developed by Professor Jon Binner and his team at the University of Birmingham, funded by DSTL and EPSRC, or a commercially available carbon-silicon carbide composite produced by Surface Transforms plc and developed for this application by Surface Transforms and MBDA. |
