The article presents the production and investigation of a bio-inspired metal–metal-composite inspired by the pomelo peel. The pomelo fruit is able to withstand a fall externally undamaged, even from heights of over 10 m most likely due to the hierarchical structuring of its foamy peel, which represents a complex composite structure. Especially the foam’s struts, which are cells from the biological point of view, consisting of liquid-filled cores and shells (cell walls) with relatively high… 
Pomelo Peel-Inspired 3D-Printed Porous Structure for Efficient Absorption of Compressive Strain Energy
The porous structure in pomelo peel is believed to be responsible for the protection of its fruit from damage during the free falling from a tree. The quantitative understanding of the relationship
A Model for the Design of a Pomelo Peel Bioinspired Foam
The structure of pomelo peel arouses research interest in recent years because of the outstanding damping and energy dissipating performance of the pomelo peel. Researchers found that pomelo peel has
Modeling and Simulation of Bio-inspired Nanoarmors
The exploitation of bio-inspired solutions and of novel nanomaterials is gaining increasing attention in the field of impact protection. Indeed, especially for advanced applications, there is a
Tensegrity structures provide a high stiffness to mass ratio since all the comprising elements are either in compression or tension. However, they have limited applications since fabrication of such
Biomechanics and Functional Morphology of Plants—Inspiration for Biomimetic Materials and Structures
During the last decades, biomimetics has attracted increasing attention as well from basic and applied research as from various fields of industry. Biomimetics has a high innovation potential and
Bio-inspired micro-to-nanoporous polymers with tunable stiffness
This approach represents a non-chemical way to tune the elastic properties and their local variation for a broad range of polymers by adjusting the pore size gradient.
Biomimetic cellular metals—using hierarchical structuring for energy absorption
It is shown how the mechanical properties of metal foam based components can be improved by altering their structure on various hierarchical levels inspired by features and principles important for the impact and/or puncture resistance of the biological role models, rather than by tuning the properties of the bulk material.
Bioinspired Hierarchical Composites
This chapter provides an overview on the limitations of currently exploited top-down and bottom-up manufacturing technologies and on the opportunities for the future development of hierarchical composites inspired by the unique multiscale structure of biological materials.


Pummelos as Concept Generators for Biomimetically Inspired Low Weight Structures with Excellent Damping Properties
Natural materials often exhibit excellent mechanical properties. An example of outstanding impact resistance is the pummelo fruit (Citrus maxima) which can drop from heights of 10 m and more without
Tough, Bio-Inspired Hybrid Materials
This work emulates nature's toughening mechanisms by combining two ordinary compounds, aluminum oxide and polymethyl methacrylate, into ice-templated structures whose toughness can be more than 300 times that of their constituents.
Structure-function relationship of the foam-like pomelo peel (Citrus maxima)-an inspiration for the development of biomimetic damping materials with high energy dissipation.
It was found here that the vascular bundles branch in a very regular manner-every 16.5% of the radial peel thickness-and that the surrounding peel tissue attains its exceptional thickness mainly by the expansion of existing interconnected cells causing an increasing volume of the intercellular space, rather than by cell division.
