Supplementary Material Available OnlineComposite materials are often made by infiltration, that is, by injecting a liquid matrix between packed solid fibers or particles. We give here direct proof that molten copper, slowly infiltrated into a broad spectrum of preforms, displays in initial phases of the process universal scaling and fractal geometric features that are characteristic signatures of percolation-dominated flow. Implications are that the microstructure of infiltrated composite materials can develop over length scales that far exceed the average preform pore size, and that network models are pertinent in the simulation of composite infiltration processing.

TiC-supported metals are systems of great importance in catalysis science and technology. Albeit their interest, catalysts based on monoliths consisting of TiC-containing carbonaceous foams have not yet been fabricated. This work aims to present a route for fabrication of mesophase pitch-derived open-pore graphite foams with TiC nanoparticles selectively distributed in two locations: at the surface of the pore cells, able for metal-support, and in the bulk, essential to achieve high degree of graphitization for
