New Study Could Help Develop Advanced Materials by Mimicking Bamboo’s Toughness and Lightness

A recent finding that throws light on biomimetic approaches in the development of materials refers to the optimization of spatial distribution of fibers in hollow bamboo cylinders in order to reinforce flexural rigidity.

[…] Researchers from Hokkaido University, Prefectural University of Kumamoto and the University of Yamanashi determined the relationship between the distribution of the reinforcing fibers in a culm and the flexural rigidity of the culm by comparing the data obtained from the real bamboo’s fiber distribution to the theoretically established optimal fiber distribution.
