Abstract (en)
[origin: WO2009080560A2] The preform technology is preferred for the production of composite materials. The preform must have a high strength and the necessary porosity for the infiltration with the liquid metal. The invention comprises the properties of the preform being improved by an appropriate selection of the size and type of the fibers and/or the particles of the secondary phase and/or the implementation of a special pore structure. In particular, the strength of the preform is increased and/or the temperature for solidifying the preform can be reduced by the use of an additional secondary phase in the nanoscale range.
