Rudolph's antlers inspire next generation of unbreakable materials

The team looked at the antler structure at the 'nano-level', which is incredibly small, almost one thousandth of the thickness of a hair strand, and were able to identify the mechanisms at work, using state-of-the-art computer modelling and x-ray techniques.
First author Paolino De Falco from QMUL's School of Engineering and Materials Science said: "The fibrils that make up the antler are staggered rather than in line with each other. This allows them to absorb the energy from the impact of a clash during a fight."

The research, published in the journal ACS Biomaterials Science & Engineering, provides new insights and fills a previous gap in the area of structural modelling of bone. It also opens up possibilities for the creation of a new generation of materials that can resist damage.
Co-author Dr Ettore Barbieri, also from QMUL's School of Engineering and Materials Science, said: "Our next step is to create a 3D printed model with fibres arranged in staggered configuration and linked by an elastic interface.
The aim is to prove that additive manufacturing - where a prototype can be created a layer at a time - can be used to create damage resistant composite material."
