Material gradients could strengthen polymer components

via Phys.org

Combining flexible and stiff materials has bestowed bamboo with a strength-to-weight ratio that rivals steel. Gradually transitioning from a soft to hard substance allows the squishy squid to slice up prey with rigid, scissor-like beaks.

With the help of a new  co-developed at the University of Nebraska-Lincoln, these two evolution-honed principles could eventually enable engineers to double or triple the strength of polymer-based components.
