BII-NACO - Bio-inspired Ultra Lightweight Nanocomposite Materials for Application to Large and Gossamer Structures in Space
Special emphasis was put on binary and ternary systems combining different nanofillers forming dedicated substructures in the host matrix. It had been observed previously that introduction of more than one nano-species may lead to synergistic effects, i.e. more than additive improvement of material properties. Moreover, spatial arrangement and orientation of nano-species are known to be crucial factors in determining overall material properties, but are typically poorly controlled.
In biology, by contrast, strong and lightweight materials generally exhibit exquisite structural control on the nanometre scale. Some of them still surpass the mechanical performance of technical materials weight by weight. Therefore, bio-inspired construction principles were extracted by review and used for the modification of existing materials based on space relevant polymer matrix systems. Technical approaches included the combination and chemical modification of nano-species and measures of structural control.
The project consortium combined interdisciplinary expertise in space technology, physics, chemistry, materials science and biology to develop such novel materials for large and gossamer structures.
