Biological materials such as bone or wood exhibit a sophisticated hierarchical structure. In particular they contain nano-sized fibrous units, the orientation of which determines the mechanical performance and can be adapted as mechanical requirements change.

For example in bone, changes in loading pattern lead to a rearrangement of mineralized collagen fibers. This is effect can be very well observed in case of implant placement and should be taken into account in clinical practice.

Also plant tissues respond to changing mechanical loads by a change of fiber arrangement. A typical example is reaction wood. Such changes can also be artificially induced and conclusions for the potential fabrication of novel and optimized nanofiber composites can be drawn.
