Hello Ulrike,
I think I can not provide new mechanical data to you. But maybe you can find
something you did not consider by now in my PhD. It is more on the energy content
of biomaterials, the time of use and how long the recycling takes - compared to
technical products. You are welcome to download the file from:
http://www.grat.tuwien.ac.at/Publikationen.html
M. Drack (2002): Bionik und Ecodesign - Untersuchung biogener Materialien im
Hinblick auf Prinzipien, die für eine umweltgerechte Produktgestaltung nutzbar
sind; Dissertation, Universität Wien
Some parts are also published in english:
M. Drack (2002): Bionics and Ecodesign: how are materials used in nature, and
what can thus be applied to sustainable product design?, in: Design and Nature:
Comparing Design in Nature with Science and Engineering
edited by: C. A. Brebbia, ISBN 1-85312-901-1
And hopefully the BIONA-report of the 6. Bionik-Kongress will emerge soon. It
also contains some parts of the PhD.
This probably does not answer your question, but eventually provides some
inspiration.
Yours, Manfred
