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 thermoplasticrntape-placement process and compared with state of the art technologies. Therefore, therntechnical and economical competitiveness must be examined.rnTo prepare this task the material and semi-finished products, as well as the productionrnprocesses, used with the new concept are classified. In order to estimate the potential for thernusage of the new concept in automotive production, the market for fiber-plastic composites inrnthis industry branch is analyzed. Additionally, a model for structuring production processesrnand the inherent cost-causing elements is chosen. After working out the restrictions andrnpossibilities of the new concept, in terms of the producibility of components, competingrnproduction techniques are identified.rnThe findings, which could be gathered so far, are then used to analyze the process and costrnstructure of the new technique and the competing techniques. Based hereupon the costs forrnproducing two products are calculated for each of the production techniques. With thisrninformation a statement about the cost-efficiency of the new technique can be made.rnFurthermore, the technical competitiveness is examined, so that the performance of the newrntechnique, compared to the state of the art technology, can be extensively described.
