Dunlop Aerogel 4D Ultimate Racketball Racket

The Dunlop Aerogel 4D Ultimate Racketball Racket features 4D braided technology which increases the stability of the racket and greatly enhances control, touch and feel. 4D stands for 4 directional braiding and is produced using four braided fibres of superlight S-glass fibre wrapped in an aluminium alloy sheath. The fibres are aligned at 0, 90, 22 and -22º orientations which enables stresses to be supported in multi directions while standard carbon sheets are only orientated in one direction. This means that one layer of 4D material has the same properties to four layers of standard carbon. As a result 4D material is four times more efficient than standard carbon. In addition, by using one layer only, 4D is also softer and less stiff than 4 layers of carbon. At 5 and 7 o’clock the multi-directional properties of the 4D braided cloth help stabilise the torsional twist at key points of the racket. At 3 and 9 o’clock one layer of 4D braided cloth provides the torsional stability previously only possible with several layers of carbon fibre. As a result of only one layer being used instead of several this softer material also provides great touch and feel at ball contact. Dunlop’s Aerogel 4D rackets perform four times better than standard carbon rackets.

Dunlop Aerogel Rackets incorporate the lightest solid which has a strength of up to 4,000 times its own weight. The three-dimensional nanometer-sized molecular network delivers a supreme strength to weight ratio for greater stiffness and increased power.
