We all know that once upon a time tennis rackets were made of wood, but how did they evolve in to the high-tech designs of today? A team at Manchester Metropolitan University has been working on this very subject and will be presenting and discussing some of their findings to the public at this year’s Manchester Science Festival.
“We were lucky enough to have hundreds of rackets from across the eras to examine” says Dr Tom Allen a Senior Lecturer in Mechanical Engineering at Manchester Metropolitan University. With his colleague Dr Luca Taraborrelli, Tom has been characterising rackets in the HEAD collection in Austria and at the Wimbledon Lawn Tennis Museum.
According to a study quoted by the team, a player with a modern racket could serve 18% faster than a player using a wooden racket from the 1870s. But how has that improvement in performance been achieved?
Using specially designed tests on rackets from different eras, the team now have a better understanding of how rackets developed and the research could even influence the future of racket design. “Because tennis is a well-funded and popular sport, developments in equipment have been faster than in some other sports," says Tom. "While the International Tennis Federation limits some racket dimensions, engineers are free to experiment with new materials and designs, allowing more innovation than in a sport like cricket where the bat must be made of wood.”
All that makes tennis a very useful subject for this kind of analysis and the implications don’t just end with tennis. Predicting the impact of changes in design technology is relevant to just about everything from the car industry to construction.
“Interesting too are the companies that fell by the wayside,” says Tom. Sometimes the cost of change was too great for even the leading brands to bear, and companies like the Belgium based Donnay, despite boasting Bjorn Borg as a player, went to the wall. “Now though with the benefits of global manufacturing these brand-names are becoming valuable again.”
As rackets moved from wood to metal and then on to graphite and other composite materials, the initial tendency was for rackets to get ever lighter and stiffer, but as the research has confirmed, the search for the best performing racket has become much more nuanced, finding the best racket for a particular player for example. These days companies like HEAD take their research and development very seriously looking for materials and design innovations to give them and the next generation of players the edge.
So can we expect rackets to continue to evolve? Yes, says the Manchester team, although the next revolution may be more about sensor technology and player feedback that the material used to build the frame. As they say, watch this racket.
