ANTIPHASE


ANTIPHASE

Antiphase™ is a brand-new technology, developed in-house by Amplid, which reduces vibrations, improving board stability. Unlike conventional damping, which relies on rubber elastomers to reduce vibrations, Antiphase™ is a multidirectional composite layer bonded to a non-Newtonian material, which is placed between the board’s or ski’s tip and binding. It disrupts the natural frequency of a ski/snowboard, stopping vibrations which otherwise amplify and end-up as tip chatter

THE PROBLEM

Uncontrolled nose chatter is destabilizing and unnerving. For the past twenty years, manufacturers of piste specific gear have side-stepped the problem by minimising tip length, using excessive camber depths and with liberal use of energy absorbing rubbers. Stiff, boring to ride and totally useless in powder, we wanted to find an alternate fix for chatter without the usual side effects.

THE INSPIRATION

Looking outside of the winter sports and sporting goods market there’s a wealth of cutting-edge industries developing innovative solutions to kill “bad vibes”. Inspired by research pioneered in the audio and aerospace industries, Amplid began developing a system which uses disruptive interference to damp vibrations. Project AntiphaseTM was born

THE SOLUTION

A series of small plates, carefully manufactured at Amplid’s factory from pre-cured, unidirectional carbon fiber are carefully orientated and adhered to a Non-Newtonian polymer sandwich. The complete system is placed in milled channels on the base side of the core, in a location where they can most effectively disrupt chatter.

THE SCIENCE

AntiphaseTM works by introducing isolated materials with a different oscillation phase to fiberglass, into the lay-up. AntiphaseTM vibrates with a different frequency and amplitude to fiberglass. Almost instantaneously the oscillations of the vibrating AntiphaseTM are out of sync with the main resonance body (the ski or snowboard) and start disrupting and damping chatter.

THE BENEFITS

AntiphaseTM provides superior chatter damping without adding noticeable weight, and it doesn’t confer a soggy, dead feel like elastomer damping. Crucially, AntiphaseTM allows Amplid to utilize nose and tip shapes designed for riding powder on skis and boards that rip hard pack. AntiphaseTM makes centrifugal riding possible in all conditions and terrain
