Carbon discs
After Venezuela, Saudi Arabia is the world's second-largest country in terms of oil reserves, ahead of Iran and Canada. Unlike the South American nation, which limits extractions, Saudi Arabia is the third-largest globally, after the USA and the Russian Federation, in terms of the quantity extracted. However, to reduce dependence on oil and diversify the economy, in 2016, the ruling house announced the strategic program Saudi Vision 2030. One of the by-products of oil distillation is pitch, one of the three materials used to make Formula 1 carbon brake discs. Pure carbon is found in nature as diamond and graphite, but for cost reasons, these materials are not used for brake discs. Instead, rings weighing 75-80 grams, consisting of rayon filaments, PAN (polymer obtained from the polymerization of acrylonitrile), or pitch are used.
