  SAIL ENGINEERING

  Sail engineering is the science of controlling our design and its behavior
  while flying. These features have been created with one goal in mind:
  Mastering the kite’s loads to maintain the desired shape for the longest
  time.

  1 – WARP TENSION LINE

  Woven fabrics feature a longitudinal 0° yarn (Warp) and a transversal 90° yarn (Weft). Therefore, a fabric has great elongation resistance and strength capacities if you apply tension at 0° or 90° along the yarns. But it will deform and stretch when tension is applied at, let’s say, 45°.

  

  

  2 – LOAD CONTROL PANELING

  When engineering the load control paneling, we make sure that fabrics panels are warp/weft oriented, meaning that the load path runs through the yarns. Fabric and seams are then in the best position to receive tensions and maintain the original kite shape.

  

   

  3 – STAGGERED SEAMS

  Most of the kite’s back lines tension is distributed through the trailing-edge panels and seams. As seams are significantly stiffer than the fabric they join, they tend to strain under loads and therefore deform the profile. The staggered seams break that line of tension by balancing the stiffness between seams and cloth, which helps distribute the load over a wider area and maintain the original shape even under high loads.

  

  4 – FABRIC WEIGHT MANAGEMENT

  Our sails feature four different cloth weights, from 52 up to 155gr/m². Sail engineering allows us to control our shape and drive load tensions without using heavy fabrics or bulky designs, therefore we can reduce fabric’s weight and use. It results in a lighter, optimized kite.

  QUADX COMPOSITE

  At F-ONE, we have developed the QuadX Composite, a laminated fabric with outstanding mechanical properties and enhanced durability. It is built on a unique four-layer architecture featuring the “Film Inside” concept. The key difference from traditional composites lies in the positioning of the PET film: in the QuadX, it is placed at the core between two fabrics, rather than on the outside.

  The QuadX is composed of:

  • Ultra-PE fabric: 5 times more tear-resistant than the best Dacron.
  • X-pattern Ultra-PE fibers: precisely angled fibers that stabilize the fabric on the bias.
  • PET Film: controls deformations in all directions, remains flexible yet efficient, and, being placed inside, is protected from external stress, preventing delamination and cracking.
  • Outer polyester fabric: protects the whole structure and reinforces all assembly seams.

  Thanks to this design, the mechanical properties of the QuadX rely on three fabric and fiber layers (Ultra-PE fabric, X-pattern Ultra-PE fibers, polyester fabric), whereas traditional composites usually only combine a single Ultra-PE fabric with one or two external films. During construction, the polyester fabric is naturally positioned on the outside of inflatable structures, as it provides the best resistance to abrasion and stitching.

  Optimized to perform in all directions (warp, weft, and bias), the QuadX Composite delivers greater strength, responsiveness, and durability, while remaining lightweight at only 125 g/m². Its robustness reduces the need for reinforcement seams during assembly, making production easier and lowering the final weight of the sail.

  HITEX

  To meet the specific needs of the development of wings and kites, and to offer a high-performance and durable product without using inaccessible materials, F-ONE has developed HITEX, a new high tenacity polyester. Available in 158g, and exclusively for F-ONE in 178g, this new material is incredibly resistant to elongation and increases the durability of wings and kites.

  HITEX is an innovative, high tenacity polyester fiber with an enhanced high-quality weaving and coating that increases the fabrics’ resistance. The 178g is a new weight and perfectly matches the needs of the center strut and center of its leading edge. The lighter 158g is used in the leading edge tips.

  Used throughout the inflatable structure of the wings and kites and designed to handle the high pressures when inflating, HITEX offers performance and resistance. Thanks to extensive Sail Engineering work, the R&D team has placed each weight of HITEX in different areas allowing absolute control of the shape session after session.

  

  The High Tenacity Polyester: HITEX.

  After working with our fabric manufacturer partners for a long time, we decided to use High Tenacity Polyester, a technical material offering a high resistance to elongation and superior durability.

  

   

  

  The HITEX is coated with PLASMA, an innovation exclusive to our supplier, which guarantees increased durability of the fabric. Coupled with high tenacity polyester fibres, it makes HITEX the most durable material on the market.

  TECHNOFORCE

  TEIJIN’s TECHNOFORCE™ is the most reliable high density polyester fabric. Its tear-stopping structure using thin and high tension yarn makes the fabric ultra-durable.

  

  It has a great proven track record of lightness and durability.

• 
  REACTOR VALVE

  The reactor inflation valve offers a high flow connection that twist locks the pump hose to the kite for an easy and super-fast inflation and deflation at the push of a button.

  It provides a high air flow rate between the struts and leading edge.

  SWEEP CONTROL PANEL

  The Sweep Control Panel provides dynamic and precise control of the wing’s sweep angle by improving tension control. Thanks to this innovation, the trailing edge remains taut, guaranteeing stability, upwind abilities, speed and long-lasting performance overtime.

  Running from wingtip to wingtip and designed with a more resistant fabric or material, this continuous panel reinforces the front part of the leading edge and helps control its rearward deformation, while maintaining lateral flex for comfort and energy transfer during pumping.

  The specific construction of the leading edge, incorporating 2 or 3 different materials and weights depending on the wing’s model, allows for its stiffness and flex to be managed perfectly and naturally throughout the entire ride. The use of these 2 or 3 ideally placed materials also saves weight on the wing.
