Dunlop Aerogel 4D 700 - Tennis Racket

The Dunlop Aerogel 4D 700 (7Hundred) tennis racket is the brand new version of the previous best selling Aerogel 700, but with the added stiffening properties of the new 4D braided frame technology. Dunlop’s Aerogel frame composition is a remarkable material; it is the world’s lightest solid which offers frame strength of up to 4000 times its own weight. The multi dimensional nano-sized molecular construction delivers an unmatched strength to weight ratio for enhanced racket stiffness and increased power, all without increasing weight. Dunlop’s brand new Aerogel 4D braided technologies represents using four braided fibres of superlight S-glass fibre wrapped in an aluminium alloy sheath in four directions. The multi directional nature of the fibres enables stresses to be supported in multiple directions, whereas standard carbon sheets are only oriented in one direction. This means that one layer of 4D material has the equivalent properties to four layers of standard carbon layered up at different directions. As a result rackets with 4D BRAIDED technologies use only one layer instead of several which makes for superb touch and feel at ball contact.
