Rudolph’s
antlers inspire next generation of unbreakable materials
Queen Mary University School of Engineering and Materials Science
Scientists from Queen
Mary University of London (QMUL) have discovered the secret behind the
toughness of deer antlers and how they can resist breaking during fights.
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."
