Southampton scientist develops strongest, lightest glass nanofibres in the world
Date:1/10/2013

The University of Southampton's Optoelectronics Research Centre (ORC) is pioneering research into developing the strongest silica nanofibres in the world.

Globally the quest has been on to find ultrahigh strength composites, leading ORC scientists to investigate light, ultrahigh strength nanowires that are not compromised by defects. Historically, carbon nanotubes were the strongest material available, but high strengths could only be measured in very short samples just a few microns long, providing little practical value.

Now research by ORC Principal Research Fellow Dr Gilberto Brambilla and ORC Director Professor Sir David Payne has resulted in the creation of the strongest, lightest weight silica nanofibres 'nanowires' that are 15 times stronger than steel and can be manufactured in lengths potentially of 1000's of kilometres.

Their findings are already generating extensive interest from many companies around the world and could be set to transform the aviation, marine and safety industries. Tests are currently being carried out globally into the potential future applications for the nanowires.

"With synthetic fibres it is important to have high strength, achieved by production of fibre with extremely low defect rates, and low weight," says Dr Brambilla.

"Usually if you increase the strength of a fibre you have to increase its diameter and thus its weight, but our research has shown that as you decrease the size of silica nanofibres their strength increases, yet they still remain very lightweight. We are the only people who currently have optimised the strength of these fibres.

"Our discovery could change the future of composites and high strength materials across the world and have a huge impact on the marine, aviation and security industries. We want to investigate their potential use in composites and we envisage that this material could be used extensively in the manufacture of products such as aircraft, speedboats and helicopters," he adds.

Professor Payne explains: "Weight for weight, silica nanowires are 15 times stronger than high strength steel and 10 times stronger than conventional GRP (Glass Reinforced Plastic). We can decrease the amount of material used thereby reducing the weight of the object.

"Silica and oxygen, required to produce nanowires, are the two most common elements on the earth's crust, making it sustainable and cheap to exploit. Furthermore, we can produce silica nanofibres by the tonne, just as we currently do for the optical fibres that power the internet."

The research findings came about following five years of investigations by Dr Brambilla and Professor Payne using Gilberto's 500,000 Fellowship funding from the Royal Society.

Dr Brambilla shared his findings with fellow researchers at a special seminar he organised recently at the Kavli Royal Society International Centre, at Chicheley Hall, in Buckinghamshire.

"It was particularly challenging dealing with fibres that were so small. They are nearly 1,000 times smaller than a human hair and I was handling them with my bare hands," says Dr Brambilla.

"It took me some time to get used to it, but using the state-of-the-art facilities at the ORC I was able to discover that silica nanofibres become stronger the smaller they get. In fact when they become very, very small they behave in a completely different way. They stop being fragile and don't break like glass but instead become ductile and break like plastic. This means they can be strained a lot.

"Up until now most of our research has been into the science of nanowires but in the future we are particularly interested in investigating the technology and applications of these fibres," adds Dr Brambilla.
