In the automobile industry, bio-based component structures such as natural fiber reinforced thermoplastics mostly use fiber fleeces as reinforcement. As example the interior door trim parts of the Golf VII are made of natural fiber fleeces. However, the component properties of natural fiber fleeces are not sufficient for load-bearing structures. Hence, their application has been limited to interior trim parts.In order to expand the use of bio-based fibers for load-bearing components, new technical and ecological synergies are necessary. The combination of a thermoplastic PP matrix with a mix of glass and flax fibers does create synergistic effects on many properties. As natural fibers bleached flax fibers are used. In addition to natural fibers, also the use of recycled short fiber reinforced PP as a matrix polymer is investigated. The present study shows that these bio-based and recycled materials can be used for load-bearing component structures. Moreover the use of process simulation as a tool for developing and optimizing the manufacturing chain of a seat shell is presented.The purpose of simulating the forming process of a structural part is to determine how the mechanical properties in the final part will be like as these properties highly depend on the fiber orientation. Therefore a draping simulation which follows the continuum mechanics approach and takes the material behavior as well as the process conditions into account was performed. Since the main objective of process simulation is to achieve the convergence between the virtual and the physical product, great care must be taken to characterize the material behavior at process relevant conditions which is the main input for an FE simulation. Therefore the material behavior was characterized in terms of thermal, mechanical and strain rate depended properties. Subsequently a crash simulation was conducted in order to analyze the crash behavior of the seat shell.
