The topic of the thesis is „Formula 1 applications of composite materials”. Composites are produced by artificially joining at least two different materials with the aim of obtaining materials with such properties that no single component has on its own. Composite materials are briefly described in the introductory part, followed by the historical course as well as a detailed description of the division of composite materials. The central part of this thesis covers the application of composite materials in Formula 1. Firstly, the history of Formula 1 is described, and then the parts of the car are described, namely the safety capsule i.e. the monocoque, powertrain, brake system, fuel tank, suspension, tires and aerodynamics. All rules related to the F1 race, driver safety, construction and design of the car are adopted by the FIA organization. The rules have been changed over the years, and huge progress has been made, which can be seen by comparing cars throughout history. The last part of this thesis shows the creation of the Formula Student car chassis, where you can see the difference between the F1 and Formula Student cars. The paper describes the chassis of the cars made by Croatian students from the FSB Racing Team. To conclude, the last section clarifies the knowledge obtained during the writing of this thesis.
