(2518)COST COMPETITIVENESS OF HYBRID STRUCTURES BASED ON THERMOPLASTIC IN-SITU TAPE-PLACEMENT PROCESS

摘要

A new production concept for hybrid structures was evaluated, based on the thermoplastic tape-placement process and compared with state of the art technologies. Therefore, the technical and economical competitiveness must be examined.To prepare this task the material and semi-finished products, as well as the production processes, used with the new concept are classified. In order to estimate the potential for the usage of the new concept in automotive production, the market for fiber-plastic composites in this industry branch is analyzed. Additionally, a model for structuring production processes and the inherent cost-causing elements is chosen. After working out the restrictions and possibilities of the new concept, in terms of the producibility of components, competing production techniques are identified.The findings, which could be gathered so far, are then used to analyze the process and cost structure of the new technique and the competing techniques. Based hereupon the costs for producing two products are calculated for each of the production techniques. With this information a statement about the cost-efficiency of the new technique can be made. Furthermore, the technical competitiveness is examined, so that the performance of the new technique, compared to the state of the art technology, can be extensively described.
