The diploma thesis deals with the design of a composite chassis module for theMODULO vehicle. The first, theoretical part of the work is focused on getting acquaintedwith composite materials as such, their history, current use and the technology of theirproduction. This part deals mainly with fibrous composite material. The practical part of thework deals with the already mentioned design of two monocoques made of carbon compositefor the MODULO vehicle. The aim of the work was to get acquainted with compositematerials in the theoretical part and to make a structural design of two monocoques fromthese composite materials in the practical part. In addition to the design, the aim of the workwas also the strength analysis of the proposed parts and technical and economic evaluationof the structural design.
