Modern brake materials in automotive engineering consist of a soft polymeric matrix with embedded SiO2particles, iron swarfs or similar materials.
For technical brake systems the stress and the temperature may increase until alloying processes between the hard particle and the wear particle flow will occur (some analysis indicates even the possibility of creating ceramic structures).

Introduction High energy mechanical milling (i.e. intense milling of metal powders, occasionally with additives) is a well known production route to form different types of nanomaterials and nanocomposites (metal-metal, metal-ceramic etc.) [1, 2].

The combination of these unique properties leads to applications of DLC coatings in diverse areas, such as wear-resistant coating for metallic, ceramic and optical materials, corrosion protection, liquid and vapor transport barriers, electronic devices, electron field emitting cathode materials, electronic packaging, passivation and thermal heat sinks [2,4].

Carbon nanotubes (CNTs) have exceptional mechanical properties, compared with other fibrous materials used in engineering polymer composites.
The latter, consists in mixing the UHMWPE and MWCNTs in a vase with the help of ceramic balls.
