Most ski manufacturers today construct their skis from a combination of wood, fiberglass, and plastic. These materials are commonly used because they are cheap and easy to work with. Using these materials results in a ski that is torsionally inferior, heavy, and less responsive.
Carbon fiber is lighter and stronger than fiberglass. Using this material enables a ski to become stiffer and much lighter in the right places, compared to a fiberglass ski. Due to the orientation of the fibers the carbon skis reach a level of torsional stiffness that is unparallelled by any other material. Torsional stiffness holds the edge at consistent angle to the surface of the snow or ice along the entire length of the ski, resulting in a much more efficient and effective edge. Carbon fiber also has the unparallelled advantage of quick reaction period. This drastically reduces the time in which the edge is separated from the snow when hitting an uneven surface during a carve, maintaining superior grip.
Carbon Fiber is not new in the skiing industry. Many manufacturers include carbon strips within their skis, and some build completely carbon skis. The difference between C6 skis and others carbon fiber skis, is the unique Autoclave Cured Carbon Prepreg (ACCP) technology that C6 has developed over 17 years in the carbon composite business. Almost any other carbon ski is constructed using the wet lamination process involving carbon cloth soaked in resin and sandwiched together. This results in a resin rich laminate, adding excess weight. Wet lamination also cannot prevent inconsistent direction of the fibers so reducing the quality of stiffness and results in a softer ski.
The C6 ACCP ski sandwich is laminated using unidirectional Prepreg carbon fiber. These skins are cooked in our autoclave at 8 atmospheres of pressure and 110 C˚. The advantage in this method of laminating is its perfect alignment of fibers. There is no scaffolding woven into it so all the fibers are straight and the laminate has considerably less resin, providing more stiffness for very little weight.
“Green flex” is an extremely tuff and flexible compound that is moulded into the sidewalls and tips of the skis. It is the perfect material to absorb the impact shocks from the edges of the skis on hard snow and ice. Green Flex together with the end grain wood core, and light weight tips creates an incredibly balanced flex profile that is well dampened and durable.
End-Grain Wood Core
All of our skis feature a lightweight end grain balsa wood core.
This type of core has long been used in the composite industry as a high density core in areas that experience significant load and frequent impacts. “End grain” means all of the grain of the wood is running vertically from the base carbon laminate to the top carbon laminate, which gives great compression and shear strength. The other advantage of this type of core is that enables a very even and consistent flex profile and great dampening.
Every C6 Ski goes through our unique pressing process. We do not use a conventional ski press when constructing our skis and have developed an original construction process in the skiing industry. We use our 6m long high pressure autoclave oven to press the ski sandwich together. Initially the skis are aligned and laminated into a vacuum bag to hold them firmly in place at 1 atmosphere of pressure. They are then rolled into our Autoclave Oven for curing. The benefits of using the Autoclave are the ability to achieve far higher, more even pressure on the entire ski. Using the Autoclave curing process we can control exactly how much pressure the ski is under and the exact temperature the resin in the ski is cured at. The result is a perfectly balanced laminate and bend profile ensuring that every ski performs smoothly and consistently.
