Abstract

Efficient lightweight solutions becoming increasingly important in the automotive industry. Since the trend of using sustainable electric engine drives is ongoing, the CO2 impact of car components is becoming more important for the overall aim to produce a CO2 neutral mobility until 2050.
So far, for automotive components almost exclusively carbon fibre reinforced plastics have been used in lightweight construction. Natural fibres offer an ecological alternative for non- or semi-structural car body parts. They exhibit, however, lower stiffness and strength than carbon fibres, but mechanical properties are sufficient for many applications for car body parts. Due to their naturally grown structure, natural fibres dampen sound and vibrations better. Their lower tendency to splinter can help reduce the risk of injury in the event of an accident. In addition, they do not cause skin irritation during processing.
The overall aim of the project is the development of a sustainable biosourced natural fibre reinforced epoxide for a car door. The research approach is a fast curing bio-sourced epoxy system for RTM (Resin Transfer Moulding) applications with a glass transition temperature >100 ℃ of the natural fibre reinforced composite. Due to its chemical structure, the bio-based epoxy resin has a tough elastic behaviour, which could offer advantages in the crash test. Among the used chemistry for the bio-sourced material, the kinetics of the bio-sourced resin will be considered and brought into relation of the whole production process. Additionally, data of dynamic thermomechanical analysis of the material will be presented.
