d3o belongs to the "smart materials" category, which is a futuristic material with abnormal behavior characteristics. More specifically, d3o belongs to a subcategory of "dilatant foams", which dramatically change their behavior under dynamic loading or impact. Integrated in the lay-up and positioned in the shaft of the racquet, d3o offers new possibilities for tennis players.
The d3o technology is able to sense the needs of the players during different strokes (it's able to adapt to you). On high-speed impacts (aggressive shots), the smart molecules lock together within nanoseconds and dramatically increase the stiffness of the whole racquet frame to provide maximum power. On slow-speed impacts (slice or drop shots), the d3o molecules absorb the impact to provide a softer touch for better feel. What does this mean to a tennis player? Passing shots are even harder and drop shots more precise, rewarding your spontaneity and supporting your courageous decisions.
Innegra is the world's lightest high performance fiber. Its extreme toughness together with Head's advanced carbon composite technology leads to an ultra tough hybrid composite.
This Head Innegra hybrid-composite structure is integrated into the racquet for shock absorption and improved stability. As a result vibrations are reduced by up to 17% on ball impact for improved control and precision -- protecting the player from the forces of a ball impact. On top of this, Head's new hybrid-composite structure with the ultra tough Innegra fiber considerably extends the performance of a Head racquet. With Innegra, racquets remain in perfect condition without losing any performance properties.
