N2 - Vapour Grown Carbon Nanofibers (VGCNFs) exhibit excellent mechanical and thermophysical properties. Therefore they are one of the most promising reinforcing materials for metal matrix composites in multiple applications, like thermal management or friction materials. The continuous manufacturing process of VGCNFs enables an immediate availability and excellent performance-to-cost ratio for the mass production of industrial components, over other candidates such as carbon fibers or nanotubes (CNTs). The present paper describes a non conventional procedure based on electroless plating for obtaining composite powders with excellent homogeneity and distribution of the nanofibers. At this stage the influence in the incorporation of nanofibers from different manufacturers has been studied in detail. A comparative study between different powder metallurgy consolidation techniques is given: pressureless sintering, uniaxial hot-pressing, hot isostatic pressing and spark plasma sintering. Complete microstructural characterization (SEM and TEM) and oxidation assessment were carried-out.
