The Dunlop Aerogel 4D 500 Tennis Racquet will allow you to experience the perfect match. To complement the raw power of AEROGEL, Dunlop has strategically inserted 4D braided touchpoints around the frame, adding up to 33% more stability and control. Hit it as hard as you want and paint the lines! This racquet is 33% stronger for added stability and control and 33% softer for unbeatable touch and feel. "4D" stands for four directional braiding and is constructed using four braided superlight S-glass fibers wrapped in an aluminum alloy sheath. The fibers are alighted at 0, 90, 22 and -22 degree orientations which enables stresses to be supported in multi-directions, whereas standard carbon sheets are only oriented in one direction. This means that one layer of 4D material has the equivalent properties of four layers of standard carbon layed up at different 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 four 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 fiber. As a result of only one layer being used, instead of several, this softer material also provides superb touch and feel at ball contact.
