heal.abstract	Developments in the field of automotive design are driven by the tendency of the industry branches to utilize materials and analysis methods for the optimization of the stiffness and weight of structures. Thus, due to the demonstration of improved properties in relation to metallic materials, composites (C.M.) take up a leading role, in the process of achieving this goal. That fact, in conjunction with the expansion of the application of the finite element analysis method (F.E.A.) over the field of composites, allows for further optimization of the designed components, through the thorough understanding of their behaviour, under specific loading conditions. The subject of this diploma thesis, deals with the optimization of the properties of a single seater race car chassis, through the improvement of its constitutive material. The dissertation begins with the presentation of the elementary information and principles of operation of the finite element software. Subsequently, the main parts of the classical laminate theory are developed and experiments are performed in order to determine the properties of the used composite materials. The resulting information, is then directed into the combination of the finite element software and the optimization algorithm, in order to determine the structural integrity and optimal lamination sequence of the composite material, from which the racing car frame is expected to be fabricated. The exported data, after being properly processed, lead to the modification of the characteristics of the sandwich material of the chassis in terms of the number and sequence and the layers of composite material from which it is composed, in order to reduce the weight and at the same time maintain satisfactory levels of torsional stiffness. Finally, a comparison is made between the findings of the simulations, leading to the recapitulation of the observations and the extraction of the final conclusions of the thesis. The information obtained both from the part of the simulations and from the experimental procedure highlights the contribution of the finite element method in the optimization of the response of the srtuctures consisting from composite materials, according to specific design factors and limitations. Additionally, the use of the optimization algorithm demonstrates the feasibility of identifying optimal solutions, without the excessive financial encumbrance that entails the repeated execution of experiments. Ultimatelly, the combination of the analysis and optimization methods proves the attainabillity of the improving the properties in the structures of race cars in order to adapt to the requirements of the applications for which they are intended.	en
