Single Seam Triaxial Carbon Fiber Reinforcement

Exegi utilizes a unique seamless triaxial carbon fiber reinforcement for both skis and boards.  Material weights and specifications are selected and optimized for specific design cases.  This method of fabrication ensures optimal energy transfer, greater durability, and increased life-cycle times.

Custom Reinforcement for Custom Results

Exeg’s approach to layup/reinforcement schedules is customer use case focused, and uses a unique “seamless"  methodology in both ski and snowboard construction.  Exegi utilizes unidirectional carbon reinforcement from tip to tail on all skis and boards  The entire core is wrapped.  Weight of reinforcement is variable based on use cases.  This is then wrapped in a +/-45 degree (in relation to the unidirectional fibers…) stitch-bonded (non-crimped) reinforcing fabric.  The reinforcement weight is varied according to use case.  This results in a triaxial reinforcement that is tuned to the individual use case in the particular ski or board.

Seamless: Better Performance and Toughness.

The core is wrapped with (+/-)45 degree fibers with the seam positioned in the middle of the top of the ski/board.  This accomplishes a few things:  First, having a single seam, far from the edges, dramatically reduces the chances for delamination due to damage.  Most structural failures of boards/skis are the result of an originally limited delamination propagating along a bond line.  Wrapping the fibers around the core eliminates seams where the propagation can occur.  The overlap in the center helps with screw retention in skis, and helps with binding edge stress risers on boards.  Second the fibers transmit stresses/loads more effectively than bonded in plastic/wood/ureathane or other sidewall/alternatives.  This results in more energy transfer, better edge grip, and more responsiveness.  Finally, the core is effectively sealed from water intrusion.


Exegi is a strong believer in the benefits provided using this construction.  It is stronger while being lighter, more damage resistant and more tolerant to damage once it happens.  Performance is enhanced.  The natural question is: Why isn’t everyone using this approach?  The answer, as usual, comes down to choices.  To weighing the  costs and the effort required versus the benefits.  Everything else is easier to do and costs less.  Our approach is utilized because its advantages outweigh the difficulties and the results make it worthwhile.
