Directly substituting bio-based materials for the high-performance materials used in aerospace engineering, however, would not lead to the desired result. The intent is therefore to combine such eco-materials with classic aerospace engineering materials to produce intelligent hybrid compounds without compromising material properties. Moreover, possible weaknesses of eco-materials shall be offset by higher degrees of functional integration. For instance, main load paths will continue to be reinforced with carbon fibers, whereas in other areas natural-fiber composites can be used to improve insulation and shock-absorbing properties.

The objectives are being implemented by means of an interactive synthesis of material composites, processing technologies and functionally integrative design. A representative model of a helicopter body shell serves to demonstrate the technology concept. To complete these efforts,

concepts related to materials management and recycling of these new composites are also being developed. Moreover, a comprehensive environmental assessment shall be made as an orientation tool for future practitioners.
