Description

Technical Field

[0001] This utility model belongs to the technical field of ski equipment, specifically, it relates to a carbon fiber surface ski. Background Technology

[0002] As a core piece of equipment in winter sports, the choice of surface material for skis has a significant impact on skiing performance, handling stability, and durability. Currently, the main surface materials for skis on the market include wood planks, alloy plates, polyethylene (PE), P-Tex, and polymer materials containing carbon or carbon fiber short fibers. While these materials can meet the basic performance requirements of skis to a certain extent, they still have limitations in terms of weight, strength, impact resistance, and durability.

[0003] For example, while wooden and alloy boards offer high rigidity, their weight makes them difficult for skiers to control for extended periods. Polyethylene (PE) and P-Tex, while having good abrasion resistance, have limited strength and are prone to deformation or even damage during high-speed skiing or impacts. Furthermore, although some polymer materials incorporate carbon or short carbon fibers, uneven fiber distribution or limited reinforcement prevents a significant improvement in the mechanical properties of the skis.

[0004] In view of the above, this utility model is hereby proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a carbon fiber surface layer ski to improve the strength, impact resistance and durability of the ski and make it lighter, thereby overcoming the shortcomings of existing ski surface layer materials in terms of weight, strength and stability.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A carbon fiber surface ski includes a surface layer, a core layer and a bottom layer stacked sequentially. The surface layer is a carbon fiber fabric cured board, and glass fiber and / or carbon fiber fabric reinforcement layers are provided between the surface layer and the core layer and / or between the core layer and the bottom layer.

[0008] Furthermore, the carbon fiber fabric cured plate is formed by curing multiple layers of carbon fiber fabric;

[0009] Alternatively, the carbon fiber fabric cured plate is formed by curing a single layer of carbon fiber fabric.

[0010] Furthermore, the multilayer carbon fiber fabric is arranged in an alternating pattern at 0°, 90° or ±45°.

[0011] Furthermore, the thickness of the carbon fiber fabric cured plate is 3.75%-8% of the overall thickness of the ski.

[0012] Furthermore, the thickness of the carbon fiber fabric cured plate is 0.3-0.4 mm, and the thickness of the ski board is 5-8 mm;

[0013] Furthermore, the thickness of the ski tip and tail is 5 mm, and the thickness of the ski waist is 8 mm.

[0014] In high-speed racing skis, higher rigidity is typically required to ensure stability during high-speed gliding and sharp turns. To this end, the thickness of the carbon fiber fabric-cured plate can be close to the upper limit of 8% to provide sufficient flexural and torsional rigidity. For example, with a total ski thickness of 8mm, the carbon fiber surface layer can be as thick as 0.64mm, thereby improving the ski's structural strength and reducing deformation or damage caused by external impacts.

[0015] For freestyle or all-terrain skis, lightweighting and flexibility are emphasized to enhance handling agility. Therefore, the thickness of the carbon fiber fabric-cured layer in these skis can be as low as 3.75%. For example, with a total ski thickness of 6mm, the carbon fiber surface layer can be 0.23mm-0.3mm thick to reduce weight, improve the skier's handling experience, and ensure smooth gliding.

[0016] Furthermore, the carbon fiber fabric of the carbon fiber fabric curing plate is woven from carbon fibers with a single bundle fiber count of 1K to 12K.

[0017] Furthermore, the carbon fiber fabric of the carbon fiber fabric curing plate is woven from carbon fibers with a single bundle fiber count of 1K, 3K, 6K or 12K.

[0018] Furthermore, the carbon fiber is at least one of T300, T400, T700 or T800 grade carbon fiber.

[0019] Furthermore, the bottom layer is a high molecular weight polyethylene sheet, and the edges of the bottom layer are provided with reinforcing steel edges.

[0020] Furthermore, the core layer is a wood board, foam board, or honeycomb board.

[0021] Furthermore, an upper reinforcing layer is provided between the surface layer and the core layer, and a lower reinforcing layer is provided between the core layer and the bottom layer. The surface layer, upper reinforcing layer, core layer, lower reinforcing layer, and bottom layer are stacked in sequence to form a laminate, and ABS sidewalls are provided at the edges of the laminate.

[0022] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art.

[0023] This invention significantly improves the overall strength and rigidity of skis by using a carbon fiber fabric-cured plate as the surface layer. Compared to traditional wood or plastic surfaces, carbon fiber materials have higher tensile strength and bending rigidity, providing more stable support during skiing and reducing the impact of ski deformation on handling performance.

[0024] Using carbon fiber as the surface material not only increases strength but also effectively reduces the overall weight of the skis. Carbon fiber has a much lower density than metals, while its strength-to-weight ratio is far higher than wood and plastics. This allows the skis to significantly reduce weight while maintaining strength, enhancing the skier's handling experience. Lighter skis reduce skier fatigue during extended use and improve flexibility, making them better suited for challenging terrain.

[0025] The inclusion of fiberglass and / or carbon fiber fabric reinforcement layers between the core and top layers, and between the core and bottom layers, further enhances the ski's impact resistance. When the ski is engaged in high-speed skiing, jumping, or impacted by external forces, these reinforcement layers effectively absorb and disperse impact energy, reducing the risk of breakage or damage. Furthermore, the presence of these reinforcement layers increases the ski's torsional rigidity, preventing excessive deformation during turns or sudden stops, thus ensuring precision and stability during skiing.

[0026] Furthermore, the addition of reinforcing layers improves the interlayer bonding of the skis, reducing delamination issues caused by long-term use. Both glass fiber and carbon fiber materials possess excellent resin wettability, enabling them to form a stronger bond with other layer materials. This prevents interlayer delamination due to changes in environmental temperature and humidity or prolonged stress, thus improving the skis' durability and lifespan.

[0027] By combining glass fiber and carbon fiber fabric reinforcement layers, the performance of the skis can be adjusted to meet different usage needs. For example, adding glass fiber can improve the flexibility of the skis, making them suitable for skiers seeking a comfortable skiing experience, while adding carbon fiber can increase the rigidity of the skis, making them more suitable for professional skiers or high-speed skiing scenarios. This flexible structural design makes the skis of this invention more widely applicable, able to meet the needs of different skiers.

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0037] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0038] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0039] As one embodiment of this utility model, such as Figures 1 to 3 As shown, this embodiment discloses a carbon fiber surface layer ski, which includes a surface layer 1, a core layer 3, and a bottom layer 5 stacked sequentially. The surface layer 1 is a carbon fiber fabric cured board, which refers to a high-strength composite board obtained by impregnating carbon fiber fabric with thermosetting resin to form a carbon fiber prepreg, followed by heating and curing the prepreg. The thermosetting resin includes epoxy resin, phenolic resin, etc. The carbon fiber fabric cured board possesses excellent properties such as lightweight, high strength, high modulus, and impact resistance. The carbon fiber fabric is woven in a plain weave, twill weave, satin weave, or unidirectional arrangement, with fibers arranged at 0°, 90°, or ±45° angles to optimize mechanical properties.

[0040] Further, a glass fiber or carbon fiber fabric reinforcement layer is provided between the surface layer 1 and the core layer 3, or between the core layer 3 and the bottom layer 5; preferably, an upper reinforcement layer 2 is provided between the surface layer 1 and the core layer 3 of the ski, and a lower reinforcement layer 4 is provided between the core layer 3 and the bottom layer 5, wherein the upper reinforcement layer 2 and the lower reinforcement layer 4 are formed of glass fiber fabric or carbon fiber fabric. The surface layer 1, upper reinforcement layer 2, core layer 3, lower reinforcement layer 4, and bottom layer 5 are sequentially coated with thermosetting resin adhesive and placed in a hot press for extrusion and heating molding.

[0041] This embodiment significantly improves the overall strength and rigidity of the ski by using a carbon fiber fabric-cured board as the surface layer 1 of the ski. Compared to traditional wood or plastic surface layers, carbon fiber materials have higher tensile strength and bending rigidity, providing more stable support during skiing and reducing the impact of ski deformation on handling performance.

[0042] Using carbon fiber as the surface layer material not only increases strength but also effectively reduces the overall weight of the skis. Carbon fiber has a much lower density than metals, while its strength-to-weight ratio is far higher than wood and plastics. This allows the skis to significantly reduce weight while maintaining strength, enhancing the skier's handling experience. Lighter skis reduce skier fatigue during extended use and improve flexibility, making them more adaptable to challenging terrain.

[0043] Fiberglass and carbon fiber fabric reinforcement layers are installed between the core layer 3 and the surface layer 1, and between the core layer 3 and the bottom layer 5, which further improves the ski's impact resistance. When the ski is skiing at high speed, jumping, or subjected to external impact, the reinforcement layers can effectively absorb and disperse impact energy, reducing the risk of ski breakage or damage. In addition, the presence of the reinforcement layers also enhances the ski's torsional rigidity, making it less prone to excessive deformation during turns or sudden stops, ensuring skiing accuracy and stability.

[0044] Furthermore, the addition of reinforcing layers improves the interlayer bonding of the skis, reducing delamination issues caused by long-term use. Both glass fiber and carbon fiber materials possess excellent resin wettability, enabling them to form a stronger bond with other layer materials. This prevents interlayer delamination due to changes in environmental temperature and humidity or prolonged stress, thus improving the skis' durability and lifespan.

[0045] By combining glass fiber and carbon fiber fabric reinforcement layers, the performance of the skis can be adjusted to meet different usage needs. For example, adding glass fiber can improve the flexibility of the skis, making them suitable for skiers seeking a comfortable skiing experience, while adding carbon fiber can increase the rigidity of the skis, making them more suitable for professional skiers or high-speed skiing scenarios. This flexible structural design makes the skis of this invention more widely applicable, able to meet the needs of different skiers.

[0046] Furthermore, as one embodiment of this invention, the carbon fiber fabric cured plate surface layer 1 is formed by curing multiple layers of carbon fiber fabric; or, the carbon fiber fabric cured plate surface layer 1 is formed by curing a single layer of carbon fiber fabric.

[0047] The surface layer 1 is formed by overlapping multiple layers of carbon fiber fabric and through resin impregnation and thermosetting processes; the specific steps are as follows:

[0048] (1) Select carbon fibers with strength of T300, T400, T700 or T800, and carbon fibers with specifications of 1K, 3K, 6K or 12K to weave into carbon fiber fabric. Choose plain weave, twill weave or satin weave structure as needed to ensure uniform weaving density. The fiber direction is staggered at 0°, 90° and ±45° to improve the bending strength and torsional rigidity of the ski.

[0049] (2) Epoxy resin or phenolic resin is used to impregnate carbon fiber fabric to form carbon fiber prepreg, which improves interlayer bonding and optimizes impact absorption capacity.

[0050] (3) Stack the layers in a manner of 2 to 6 layers to ensure that the resin is evenly distributed between the layers and to avoid air bubbles; the fiber direction is staggered to optimize the direction of force so that the ski has both good rigidity and a certain degree of toughness when subjected to impact.

[0051] (4) The laminated carbon fiber fabric is fed into a hot press and heated at 150℃-200℃, and pressure of 0.3-0.6MPa is applied to ensure that the resin is completely cured and the carbon fiber fabric becomes an integral structure. After cooling, a carbon fiber fabric cured board surface layer 1 with a thickness of 3.75%-8% of the total thickness of the ski is formed.

[0052] This technical solution optimizes the strength, rigidity, impact resistance and overall durability of the skis by using multi-layer carbon fiber fabric laminated and cured to form the surface layer 1, enabling the skis to better adapt to high-speed skiing, complex ski slope environments and high-intensity use requirements.

[0053] In this embodiment, carbon fibers of different strength grades (T300, T400, T700, T800) are selected and woven with fiber bundles of 1K, 3K, 6K, and 12K specifications to ensure good structural uniformity of the carbon fiber fabric. Plain weave, twill weave, or satin weave structures are selected according to requirements, ensuring excellent mechanical properties of the surface layer in different stress directions. This design not only improves the tensile strength of the skis but also ensures the stability and durability of the material.

[0054] During the installation of carbon fiber fabric, the 0°, 90°, and ±45° staggered arrangement effectively improves the flexural strength and torsional rigidity of the skis. This fiber installation method can distribute the stress when the skis are subjected to bending or torsional stress, enabling them to maintain excellent stability during high-speed skiing or sharp turns, while reducing the risk of damage caused by localized stress concentration.

[0055] Carbon fiber fabric is impregnated with epoxy or phenolic resin to form a prepreg, which enhances the interlayer bonding of the fibers, making the surface layer a monolithic structure and improving impact resistance and fatigue resistance. Through lamination and curing of 2 to 6 layers of carbon fiber fabric, uniform resin distribution between layers is ensured, and air bubbles are avoided, improving overall quality and structural stability. Simultaneously, a hot-pressing process at 150℃-200℃, applying a pressure of 0.3-0.6MPa, ensures complete resin curing, guaranteeing good strength and toughness in the surface layer. The resulting cured carbon fiber fabric board accounts for 3.75%-8% of the total thickness of the ski, achieving a balance between high strength and lightweight, allowing the ski to achieve superior mechanical properties without adding extra weight.

[0056] In another embodiment of this invention, the bottom layer 5 is a high-molecular-weight polyethylene sheet, which is formed by hot pressing or extrusion of high-molecular-weight polyethylene. The bottom layer 5 has a reinforcing steel edge 7 along its edge, which covers the bottom and side edges of the bottom layer 5, and is formed directly from a single piece of high-carbon steel or stainless steel sheet.

[0057] The reinforced steel edge 7 provides a continuous, seamless coverage along the edge of the bottom layer 5, forming a complete metal frame from the tip (front), middle, and tail (rear) of the ski. This design offers maximum edge protection and ensures the ski edges maintain excellent grip and stability throughout the skiing process.

[0058] Alternatively, the reinforced steel edge 7 can be installed only in specific areas of the ski, such as the nose, waist, or tail, while the rest of the ski retains the exposed structure of the polyethylene underlayer 5. This method reduces the weight of the ski while maintaining necessary grip and improves maneuverability, making it particularly suitable for freestyle and recreational skiing.

[0059] Furthermore, the reinforcing steel edge 7 at the tip of the ski features a V-shaped acute angle design, with the convex angle facing the direction of the ski's forward movement, i.e., the tip. This effectively reduces skiing resistance, allowing the ski to cut into the snow more smoothly, increasing starting speed, and reducing sticking on soft snow.

[0060] In the waist section of the ski, the reinforced steel edge 7 continues to use a V-shaped acute-angle blade, but its angle is usually controlled within the range of 55°-70° to enhance grip and improve skiing stability. During high-speed skiing, skiers typically rely on the waist section of the ski for leverage; therefore, the steel edge in this area needs to have strong grip and durability to ensure the ski is less prone to slipping or losing control during sharp turns, braking, or fast skiing. The deep cut of the V-shaped acute angle allows the ski to firmly "grip" the snow, giving skiers a more precise control experience at high speeds.

[0061] At the tail of the ski, the reinforced steel edge features a U-shaped, smooth blade. This design provides a more stable contact surface during gliding, allowing the ski to separate more smoothly from the snow when turning or braking, avoiding the jerking sensation caused by sudden stops. Simultaneously, the U-shaped blade offers better adaptability on complex terrain, ensuring a smooth and fluid gliding experience in soft, powder, or wet snow.

[0062] The reinforced steel edge 7 is installed using either an embedded or replaceable mounting method. In the embedded installation, a groove is pre-cut into the edge of the bottom layer 5 of the ski, into which the steel edge is embedded and securely fastened using epoxy resin combined with mechanical fastening. This installation method is suitable for high-performance skis, providing more stable grip and reducing the risk of loosening after prolonged use. In the replaceable installation, the steel edge is fixed using a screw and rail structure, allowing skiers to change the shape of the steel edge according to different snow conditions. For example, a V-shaped acute-angle steel edge can be used on hard snow or ice, while a U-shaped smooth steel edge can be used on soft snow to adapt to different skiing needs.

[0063] The reinforcing steel edge 7 can be a solid high-density structure; or, the reinforcing steel edge 7 can be a lightweight hollow structure with hollow holes, which reduces weight while maintaining strength; or, the reinforcing steel edge 7 can be provided with several U-shaped notches, which are evenly arranged along the edge of the bottom layer 5, and absorb edge impact energy through local flexible deformation.

[0064] Furthermore, in this embodiment, the core layer 3 is a wood board, foam board, or honeycomb board. Specifically, the core layer 3 is made of laminated hardwood lumber (LVL) or reconstituted wood substrate; or, the core layer 3 is made of polyurethane (PU) or polyvinyl chloride (PVC) foam; or, the core layer 3 is made of aluminum alloy sheet molded into a honeycomb board with a continuous hexagonal lattice structure.

[0065] This embodiment offers a variety of options for skis, combining high strength, high rigidity, lightweight, and durability, through a core layer 3 structure design with different materials. Wooden core layers 3 are suitable for skiers seeking precise control, polyurethane (PU) or polyvinyl chloride (PVC) foam core layers 3 are suitable for recreational skiers, while aluminum alloy honeycomb core layers 3 provide extreme performance support for high-end competitive skis. By rationally selecting core layer materials, different skiing styles and scenarios can be met, optimizing the skiing experience.

[0066] Furthermore, an upper reinforcing layer 2 is provided between the surface layer 1 and the core layer 3, and a lower reinforcing layer 4 is provided between the core layer 3 and the bottom layer 5. The surface layer 1, upper reinforcing layer 2, core layer 3, lower reinforcing layer 4, and bottom layer 5 are sequentially stacked to form a laminate. An ABS sidewall 6 is provided at the edge of the laminate. The ABS sidewall 6 is made of acrylonitrile-butadiene-styrene copolymer (ABS), which has high impact resistance, abrasion resistance, and aging resistance. The ABS sidewall 6 is manufactured by extrusion molding or compression molding and is tightly bonded to the side of the laminate of the ski through hot pressing to provide additional edge protection, enhance the impact resistance of the ski, and improve durability.

[0067] In this utility model, firstly, T300, T400, T700 or T800 grade carbon fibers are selected to weave carbon fiber fabric. The width of the carbon fiber fabric can be 127MM. The carbon fiber fabric is impregnated with epoxy resin or phenolic resin and then hot-pressed and cured to form a carbon fiber fabric cured plate surface layer 1.

[0068] Subsequently, the core layer 3 can be made of wood, foam, or honeycomb board, and is cut with CNC machining to ensure precise dimensions. Fiberglass or carbon fiber reinforcement layers are laid on both sides of the core layer to improve impact resistance and rigidity. The bottom layer uses high-molecular-weight polyethylene (UHMW-PE) sheets, which are graphite-filled or fluorinated to optimize gliding performance. Reinforcing steel edges 7 are fixed to the edge of the bottom layer to improve grip and durability, while ABS sidewalls 6 are extruded or molded and installed on the sides of the ski using thermoforming or mechanical fastening to enhance overall structural stability.

[0069] All layers of this invention are cured in a hot press at 150-200℃ and 0.3-0.6MPa to ensure a tight bond between each layer. After molding, the skis undergo computer-controlled cutting, grinding, and polishing, and a uniform coating of ski wax is applied to the bottom layer to improve gliding smoothness and durability. Finally, after rigorous quality testing, the skis are professionally packaged to ensure safe transportation and high-quality delivery.

[0070] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. The implementation schemes in the above embodiments can also be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
