Zusammenfassung (Englisch)

The use of carbon composites in the automotive industry is of increasing importance because of its low weight and advantageous mechanical properties to volume ratio. In spite of all the positive attributes associated with carbon fibre, its full potential in the automotive industry is not yet realized. Currently, it is used for external applications of vehicles only. A majority of the suspension components in vehicles, such as gearbox holders, are still made up of metals because they have load bearing capability during service. The use of carbon fibre requires more design, fabrication and testing to attain its optimum mechanical properties. Furthermore, high material costs have to be taken into account as well. However, a well designed carbon composite component is superior to its steel counterpart in many applications. In recent years, computer aided design (CAD) and finite element analysis (FEM), opened up new possibilities for the design of such components. In an effort to check the integrity of numerical analysis for fabricated components, a gearbox holder made up of woven carbon fibre laminates was fabricated. Mechanical testing was carried out to obtain input parameters for numerical simulations in NX 10.0 (Siemens Product lifecycle Management Software Incorporated). Initially, optimizations for ply-lay-up as well as ply orientation were carried out. Flat patterns obtained by draping simulation were used for the lamination of gearbox holder parts. Mechanical measurements on carbon fibre specimens and the entire component were performed. For the simulation, the Maximum stress and Tsai-Wu failure theories were employed. The experiments showed good correlations to the failure predicted by the simulation.
