Dunlop Biomimetic 200 Tour Racquet Technologies
Aerogel is the world's lightest solid. It has strength up to 4,000 times its own weight. Aerogel's nanometer-sized molecular network delivers an unmatched strength to weight ratio for enhanced stiffness and power. Aerogel racquets offer incredible power with touch and feel without compromising weight.
4D stands for 4 directional braiding.
It is contructed using four braided fibres of superlight S-glass fiber wrapped in an aluminum alloy sheath.
The fibres are aligned at 0, 90, 22 and-22û orientations which enables stresses to be supported in multi-directions whereas standard carbon sheets are only orientated in one direction. This means that one layer of 4D material has the equivalent properties to four layers of standard carbon layed up at orientations. Consequently 4D material is four times more effective than standard carbon. Furthermore, by using one layer, 4D is also softer and less bulky than 4 layers of carbon.
At 5 and 7 o'clock the multi-directional properties of the 4D braided cloth help stabilize the torsional twist at key points of the racquet.
At 3 and 9 o'clock one layer of 4D braided cloth provides the torsional stability previously only achievable with several layers of carbon fibre. As a result of only one layer being used instead of several this softer material also provides superb touch and feel at ball contact.
This technology is inspired by shark skin. The unique surface appplication is strategically applied to the racquet frame. The dimpled texture creates localized turbulence and streamlines airflow over the racquet surface. This reduces drag by up to 25%, resulting in a faster racquet speed for more power.
This technology is inspired by a bee's honeycomb. High modulus carbon fiber is engineered into hexagonal sheets and is placed between layers of Aerogel-enhanced carbon. These hexagonal sheets help evenly distribute impact forces and absorb unwanted racquet frequencies to enhance feel up to 10%. The HM6 Carbon reduces energy loss and maximizes energy return.
This unique nano-scopic surface treatment on the grip is inspired by gecko setae. The perforated design increases moisture reduction and provides up to 50% more grip and tack. This results in enhanced control, precision and comfort.
