Carbon fibre is a material consisting of extremely thin fibres about 0.005–0.010 mm in diameter and composed mostly of carbon atoms. The carbon atoms are bonded together in microscopic crystals that are more or less aligned parallel to the long axis of the fibre. The crystal alignment makes the fibre very strong for its size.

The density of carbon fibre is also considerably lower than the density of steel, making it ideal for applications requiring low weight. The properties of carbon fibre such as high tensile strength, low weight, and low thermal expansion make it very popular in aerospace, civil engineering, military, and motorsports, along with many other competitive sports.

Carbonautica's manufacturing facility is in the City of Velenje. Slovenia's 5th biggest city, it is the centre of the Municipality of Velenje with approx. 30.000 habitants. Established in 1959, City of Velenje has made tremendous efforts to recultivate landscapes ruined by coal exploitation and turn handicap into advantage. Velenje lakes have become a tourist attraction and recreational centres abound including the  city's famous 75 metre championship Ski Jump.The area of present Velenje was first mentioned in 1250.

The city boasts a highly skilled and educated workforce.            .
