In times of advances in technology and the need for a wide variety of products of all possible shapes, and with the requirements for the smallest possible mass and the greatest possible rigidity (the greatest possible resistance to deformations of the structure), composite structures are often desired or the only possible choice, as they can be shaped very differently, and also to determine their strength very precisely by choosing the thickness of the composite layers. Carbon fibers are often used for composite structures, which are highly desirable in terms of weight-to-strength ratio, especially in the automotive world, especially in motorsport, and in aerospace engineering. Therefore, in the Formula student association we develop the car around a composite chassis(monocoque), as this ensures high rigidity of the primary structure of the car(chassis), which is the basis for good performance of other components and the entire car. By measuring the deformations and consequently determining the displacements of the primary structure of the car, we can determine the size of the deformations and thus obtain the relationship between the deformations and the thickness of the composite structure(laminate). By knowing this connection, we can already know approximately the deformations and displacements that will occur when driving a car when designing further racing cars and determining the thickness of the composites on the chassis.
