Fecha de publicación: | may-2009 | Editor: | Springer Nature | Citación: | Journal of Materials Science 44(10): 2525-2532 (2009) | Resumen: | [EN] The development of titanium-doped carbon matrix–carbon fibre reinforced composites (CCCs) via liquid impregnation of carbon fibre preforms using mesophase pitch is studied. Two different approaches for introducing the dopant into the carbon material are investigated. One consists of doping the matrix precursor followed by the densification of the preform with the doped precursor. The second approach consists of doping the porous preform prior to densification with the undoped mesophase pitch. Titanium-doped CCCs with a very fine distribution of dopant (in the nanometric scale) are obtained by adding TiC nanoparticles to the matrix precursor. Thermal decomposition of titanium butoxide on the carbon preform prior to densification yields doped CCCs with higher titanium content, although with larger dopant size. The combination of these two methods shows the best results in terms of dopant content. | Versión del editor: | http://link.springer.com/article/10.1007%2Fs10853-009-3327-9 | URI: | http://hdl.handle.net/10261/88737 | DOI: | 10.1007/s10853-009-3327-9 | ISSN: | 0022-2461 | E-ISSN: | 1573-4803 |
