A fabrication method for fabricating an equipment part for an automotive vehicle. The method includes the following steps. Supplying a sheet comprising ceramic fibers and thermofusible polymer fibers, the melting temperature of the thermofusible polymer being higher than 200° C. Heating the sheet, at a temperature higher than 200° C., so as to melt the thermofusible polymer. Applying a fabric on the sheet, the fabric comprising filament yarns having a core made of polymer presenting a softening point temperature that is higher than or equal to 200° C. And then thermoforming of the fabric and the sheet in a conforming mold.
