the first material used in the production of automotive brake discs were gray cast iron with the following
properties: good diffusivity and thermal conductivity, corrosion resistance, abrasion stability, low weight, low noise, durability, operational and
low price. From a technological standpoint, over time, they have been made a large number of experiments, especially with thebeginning of
the Second World War. Therefore, for more than one hundred years, have seen more materials intended to meet all these features, but until
now the most used material in large scale production of brake discs was still the gray iron. The paper presents the evolution of materials used in
making brake discs and order research in the composite material and the positive implications of their use in the automotive industry.
