BIO-BASED MATERIALS FOR EXTERIOR APPLICATIONS – PROJECT BIOHYBRIDCAR

The objective of this work is to evaluate the possible uses of bio-based materials (natural fibres, matrix systems) and hybrid material concepts for sustainable mobility. In the first stage, this has been elaborated for a door frame and door panel of a Porsche Cayman GT 4 Clubsport (981) as a test vehicle. On this demonstrator vehicle, the material concepts optimised in the laboratory for selected components are intensively tested in practice in the VLN racing and their suitability for serial production of various exterior components will be analysed. The holistic view is divided into three main points: Technical evaluation (mechanics, vibration, semi-finished products, design, calculation) Ecology (LCA) Economy (supply chain, availability, production process, processability) This article is focused on the first results of the technical evaluation for the door frame and gives a first outlook on the ecology and economy aspects for the used materials. As part of the project, various exterior components are manufactured under different weighted aspects that allow the comparison of carbon, natural and, especially, hybrid fibre reinforced plastics, thereby highlighting the specific advantages of different material combinations, e.g. using a combination of flax and carbon fibres for reinforcement. In addition to the technical feasibility in terms of material properties and the processing methods as well as an ecological consideration, in particular the economic feasibility of these materials is considered. The following chapters present the fundamental strategy of the project which is to transfer the results to a sustainable mobility in the future.
