Next-Gen Auxetic Dynamics: Transverse CNC Cutouts with Mid-Density EPP Core
Harnessing Auxetic Geometry to Revolutionize Ball Dwell Time, Spin Generation, and Energy Return.
Traditional paddle faces resist deformation uniformly, which limits dwell time and energy transfer efficiency. Our Auxetic Cutout Concept breaks away from rigid conventions by integrating 5 transverse precision CNC channels into a resilient Mid-Density EPP (400–440g) core, framed by an ultra-lightweight TPE perimeter. The result is a paddle that dynamically responds to ball impact with unprecedented control and mechanical feedback.
Structural Blueprint Breakdown
1. Transverse “Auxetic” CNC Surface Cutouts
Precision Engineered Flex Channels (12mm Width / 4mm Depth):
Milled horizontally across the core at 26mm intervals, these dual-sided V-shaped cutouts create an auxetic deformation pattern upon impact. This geometry expands local ball contact dwell time for extreme spin manipulation and vibration dampening.
2. Mid-Density EPP Performance Engine
Balanced Power & Resiliency (400–440g):
Serving as the structural foundation, the 400–440g EPP foam core maintains torsional stability while offering a punchy, responsive rebound once the ball leaves the auxetic flex zone.
3. Ultralight TPE Perimeter Frame
Perimeter Protection Without Heavy Swingweight:
Encapsulated in a specialized Lightest Grade TPE boundary, this outer rim protects the internal EPP core against edge impact while swallowing high-frequency shock waves before they hit the handle.
