63% Toughness Leap: 3D Printed Double Helix Structure Concrete by Robots
AbstractNature has evolved numerous design paradigms by organizing basic materials into complex structures. The damage-resistant double helix structure (double-bouligand) found in the scales of the coelacanth is composed of collagen fibers arranged in a double helical manner. This study applies the toughening mechanism of the double helix design to the preparation of structured concrete using … Read more
