Yonex ASTROX badminton rackets use a world’s first, new dimension Graphite material, Namd, which greatly improves the adhesion of the graphite fibers and resin by attaching nanomaterial directly to the Graphite fiber.
In high-performance racquets, it is common to combine nanomaterials with resin that connects Graphite fibers, but in Namd, nanomaterials directly adhere to the graphite fibers and the degree of adhesion between Graphite fibers and resin is greatly increased. This major improvement produces a shaft that flexes and stores energy, delivering explosive force on impact with the shuttle.
Full Racquet Namd*
The ASTROX 99 badminton racket has adopted Namd in the entire body of the racquet, including the frame. This doubles contact time with the shuttle, resulting in an explosive shot, as the racquet returns from flexed to straight at the end of the swing.
At high speeds, the new shaft makes a longer stroke in the same time frame. From the initial movement of the player to the impact, the new dimension Graphite is difficult to harden, and the shaft extends and accumulates energy due to the speed of the fast swing. Since the follow-through of the swing is smaller after direct impact with the shuttle, the swing speed drops and the new dimension Graphite regains hardness and strengthens the resilience of the shaft, allowing the energy to explode rapidly before returning to its original state.
At slower swing speeds, the new shaft maintains stability for better control on drives.
