F1 cars composite is made by processing carbon fiber in an autoclave machine. Each stage of making a chassis uses the autoclave. Different parts are processed at different temperatures and different pressures in a vacuum, to extract air from the material.
Two crucial parts that a carbon fiber chassis goes through in an autoclave are debulking and cure. The autoclave is being used to cure composite parts on F1 racing cars. F1 cars use carbon fiber because of its high rigidity and strength with low weight.
