Description

Technical Field

[0001] This invention relates to the field of ski technology, and in particular to a novel ski panel and its manufacturing method. Background Technology

[0002] Skis are the core equipment of skiing, invented in Northern Europe in the early 20th century, primarily used to improve skiing speed and control. Their structure is made of multiple layers of composite materials, including a flexible core, a polymer ski base, fiberglass layers, and metal edges. The base comes in two types: melt-molded and extruded, with the latter often used in professional settings due to its speed advantage. Based on their purpose, they can be categorized into alpine skis, freestyle skis, snowboards, and off-piste skis. Length is usually adjusted according to height, and the degree of flexibility directly affects handling. Existing ski manufacturing processes such as Figure 3 As shown, the process involves placing steel edge strips, placing the bottom of the ski, a lower layer of fiberglass, poplar wood, an upper layer of fiberglass, an upper panel, and finally shaping it into a ski. After a few years of use, it is scrapped.

[0003] Existing skis are heavy, the panels are prone to delamination, they are not recyclable, and they are not environmentally friendly. Therefore, we propose a ski panel and its manufacturing method to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing skis, such as heavy weight, easy delamination of the ski panel, non-recyclability, and lack of environmental friendliness, and to propose a ski panel and its preparation method.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A ski panel includes a steel edge strip, a ski bottom is provided inside the steel edge strip, a lower layer of fiberglass is provided on the top of the ski bottom, poplar wood is provided on the top of the lower layer of fiberglass, an upper layer of fiberglass is provided on the top of the poplar wood, a polytetrafluoroethylene composite film is provided on the top of the upper layer of fiberglass, and a rubber strip is provided on the steel edge strip.

[0006] This invention also proposes a method for preparing a ski panel, comprising the following steps: S1. First, place the steel edge strip, and then place the ski bottom inside the steel edge strip; S2. Install a lower layer of fiberglass on the top of the ski bottom, and place poplar wood on top of the lower layer of fiberglass. S3. A top layer of fiberglass is placed on top of the poplar wood, and a polytetrafluoroethylene composite film is placed on top of the top layer of fiberglass to shape it into a ski. S4. After a few years of use, a new polytetrafluoroethylene composite film is laid and shaped into a new ski.

[0007] The polytetrafluoroethylene (PTFE) composite film is printed with patterns. Both the upper and lower fiberglass layers are made of glass fiber. The printing process is as follows: the desired pattern is printed onto the PTFE composite film using digital printing or screen printing. The printed side of the PTFE composite film is then laid flat on the epoxy resin-coated fiberglass and heat-set on a press. After setting, the PTFE composite film is removed. This method reduces the weight of the skis by more than 300 grams due to the absence of a traditional panel. A layer of clear varnish is evenly sprayed onto the fiberglass surface and then cured using a UV curing machine. Through these processes, the varnish and ink directly penetrate and adhere to the fiberglass and epoxy resin, instead of having an additional panel on the top layer of the skis as in traditional processes. This makes the ski surface more scratch-resistant and less prone to cracking. Most importantly, the PTFE composite film can be reused to change patterns and refurbish the skis, making them more environmentally friendly and reusable.

[0008] Preferably, the skis shaped in S3 are weighed to a weight of 2600 grams.

[0009] Preferably, the skis shaped in S3 are subjected to a slapping test, and do not crack after being slapped 15 times.

[0010] Preferably, an elasticity test was conducted on the skis shaped in S3, and the result was 48.7 mm.

[0011] Preferably, the snow adhesion test is performed on the skis shaped in S3, and the test results show that they do not easily adhere to snow.

[0012] The beneficial effects of the ski panel and its preparation method described in this invention are as follows: Significant weight reduction: By using a polytetrafluoroethylene composite film instead of a traditional panel, the overall weight of the ski is reduced by more than 300 grams (for example, the weight of the ski after shaping is only 2600 grams), making the ski lighter, easier to carry and control, and improving the sports experience.

[0013] Environmentally friendly and recyclable: After a few years of use, skis do not need to be completely scrapped. Simply lay a new PTFE composite film on them to reshape them into new skis. This design allows for multiple refurbishments and reuses, reducing waste generation, aligning with sustainable development principles, and making them more environmentally friendly.

[0014] Enhanced durability and damage resistance: By directly penetrating and bonding varnish and ink to the fiberglass and epoxy resin, the board surface is more scratch-resistant and less prone to cracking (no cracking after 15 taps). This extends the lifespan of the skis and reduces maintenance costs.

[0015] Flexible and easy-to-update pattern customization: PTFE composite film supports digital printing or screen printing patterns, allowing users to easily customize or change designs according to their preferences. During renovation, simply replacing the film is sufficient to update the appearance, meeting individual needs while avoiding the complex process of traditional panel replacement.

[0016] Improved skiing performance: Snow adhesion tests show that the skis do not easily stick to snow, which helps maintain smooth skiing. Elasticity tests show an elasticity of 48.7mm, ensuring good control and responsiveness, thus enhancing athletic performance.

[0017] Simplified manufacturing process: The preparation method reduces the traditional panel layers and directly integrates the polytetrafluoroethylene composite film through a heat setting process, making the process simpler and potentially reducing production costs and improving production efficiency.

[0018] The board of this invention is lighter, stronger, scratch-resistant, crack-resistant, snow-resistant, environmentally friendly, and recyclable. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] Example 1 Reference Figures 1-5 A ski panel includes a steel edge strip 6, a ski bottom 7 inside the steel edge strip 6, a lower layer of fiberglass 4 on top of the ski bottom 7, poplar wood 3 on top of the lower layer of fiberglass 4, an upper layer of fiberglass 2 on top of the poplar wood 3, a polytetrafluoroethylene composite film 1 on top of the upper layer of fiberglass 2, and a rubber strip 5 on the steel edge strip 6.

[0023] This embodiment also proposes a method for preparing a ski panel, including the following steps: S1. First, place the steel edge strip 6, and then place the ski board bottom 7 inside the steel edge strip 6; S2. A lower layer of fiberglass 4 is installed on top of the bottom 7 of the ski board, and poplar wood 3 is placed on top of the lower layer of fiberglass 4. S3. A top layer of fiberglass 2 is placed on top of poplar wood 3, and a polytetrafluoroethylene composite film 1 is placed on top of the top layer of fiberglass 2 to form a ski. S4. After several years of use, lay a new polytetrafluoroethylene composite film 1 and shape it into a new ski.

[0024] Specifically, I. Preparations and Materials Material preparation: Structural materials: steel edge strips, high-molecular-weight ski board bottom (usually ultra-high molecular weight polyethylene UHMW-PE), pre-impregnated or unimpregnated fiberglass cloth (upper and lower fiberglass layers), and poplar wood (usually laminated wood, such as birch or poplar).

[0025] Core innovative material: Polytetrafluoroethylene (PTFE) composite film. This film has excellent anti-sticking and heat resistance, and can be easily peeled off after hot pressing, leaving only the patterned layer.

[0026] Adhesive and coating materials: epoxy resin system (including resin and curing agent), UV-cured varnish.

[0027] Pattern material: Special outdoor weather-resistant ink.

[0028] Equipment and tools: Ski hot press (a press table that can provide specific temperature, pressure and time control).

[0029] UV curing machine.

[0030] Digital printers or screen printing equipment.

[0031] Epoxy resin coating equipment (such as squeegee, roller coater or manual brush).

[0032] Vacuum bag compression system (optional, used to remove interlayer air and enhance lamination quality).

[0033] II. Detailed Preparation Steps Phase 1: Forming the Main Structure of the Skis S1. Mold preparation and base layer laying Clean the mold of the skis and apply a release agent to facilitate subsequent demolding.

[0034] The steel strip 6 is precisely placed in the predetermined slot of the mold.

[0035] Place the cut ski bottom 7 into the mold, ensuring it is inside the frame made of steel strips and fits tightly against the steel strips.

[0036] S2, Core Layer Laying On top of the ski board bottom 7, lay a layer of pre-impregnated epoxy resin-impregnated fiberglass 4 or dry fiberglass cloth, followed by resin coating.

[0037] The processed poplar wood 3 is precisely placed on top of the lower layer of fiberglass 4. The poplar wood is a key component that determines the ski's elasticity and torsional performance.

[0038] S3. Upper layer structure and pattern transfer: S3.1 Epoxy Resin Coating: On top of the poplar wood 3, lay the upper layer of fiberglass 2.

[0039] Using a coating tool, apply a measured amount of epoxy resin evenly to the surface of the upper fiberglass layer 2. This resin layer serves as both a lamination adhesive and a carrier for the pattern.

[0040] S3.2 Polytetrafluoroethylene composite membrane laying: Take out the polytetrafluoroethylene composite film 1, which has been pre-printed with the desired pattern by digital printing or screen printing.

[0041] With the patterned side of the membrane facing down, lay it precisely and smoothly onto the top layer of fiberglass 2 that has just been coated with epoxy resin. Ensure there are no air bubbles or wrinkles between the membrane and the fiberglass.

[0042] S3.3 Hot pressing and shaping: The entire laid "sandwich structure" is then fed into a hot press.

[0043] Based on the epoxy resin system used, precise hot-pressing parameters were set: temperature 110°C, pressure 3 Bar, and time 17 minutes. Under the combined action of heat and pressure, the epoxy resin cured, firmly bonding the fiberglass, wood core, ski bottom, and steel edge strips into a single unit.

[0044] Under the influence of heat, the ink on the polytetrafluoroethylene composite film detaches from the film, completely transfers and penetrates into the underlying cured epoxy resin and glass fiber layers, forming a permanent pattern.

[0045] S3.4 Peel off the protective film: After hot pressing and shaping, the formed skis are removed from the press.

[0046] Once the temperature has dropped to a safe range, use your hands or a tool to easily peel off the PTFE composite film 1, starting from the edge. At this point, the smooth, vibrant pattern remains on the ski surface, while the PTFE film itself is removed.

[0047] S3.5 Surface curing treatment: Apply a layer of UV-cured varnish evenly to the surface of the board with the transferred pattern.

[0048] Immediately pass the skis through a UV curing machine. Under the irradiation of ultraviolet light of a specific wavelength, the varnish cures rapidly within seconds.

[0049] The purpose of this step is to: enhance weather resistance: protect the pattern from UV radiation and climate aging; improve abrasion resistance: make the surface more scratch-resistant and abrasion-resistant; and improve surface properties: create a smooth, snow-resistant surface.

[0050] The polytetrafluoroethylene (PTFE) composite film 1 is printed with a pattern. Both the upper fiberglass layer 2 and the lower fiberglass layer 4 are made of fiberglass. The printing process is as follows: the desired pattern is printed onto the PTFE composite film using digital printing or screen printing. The printed side of the PTFE composite film is then laid flat on the fiberglass layer coated with epoxy resin and heat-set on a pressure table. After setting, the PTFE composite film is removed. This method reduces the weight of the ski by more than 300 grams due to the absence of a traditional panel. A layer of clear varnish is evenly sprayed onto the fiberglass surface and then cured using a UV curing machine. Through these processes, the varnish and ink directly penetrate and adhere to the fiberglass and epoxy resin, instead of having an additional panel on the top layer of the ski, making the surface more scratch-resistant and crack-resistant. Most importantly, the PTFE composite film can be reused to change patterns and refurbish the skis, making them more environmentally friendly and reusable.

[0051] In this embodiment, the skis shaped in S3 are weighed and the weight is 2600 grams.

[0052] In this embodiment, the skis shaped in S3 were subjected to a slapping test, and they did not crack after being slapped 15 times.

[0053] In this embodiment, an elasticity test was conducted on the skis shaped in S3, and the result was 48.7 mm.

[0054] In this embodiment, a snow adhesion test was conducted on the skis shaped in S3, and the test results showed that they did not easily adhere to snow.

A top layer of fiberglass 2 is placed on top of poplar wood 3, and a polytetrafluoroethylene composite film 1 is placed on top of the top layer of fiberglass 2 to form a ski. S4. After several years of use, lay a new polytetrafluoroethylene composite film 1 and shape it into a new ski.

[0115] In this embodiment, the skis shaped in S3 are weighed and the weight is 2600 grams.

[0116] In this embodiment, the skis shaped in S3 were subjected to a tapping test, and they did not crack after being tapped 15 times. Details are as follows: I. Experimental Objective Simulating skis jumping, flipping, and impacting snow and hard objects at high speeds, this test examines the bonding strength of the interlayer structure (especially the junction between the pattern transfer layer and the upper fiberglass layer) and the overall impact resistance, ensuring that there will be no cracking, delamination, or pattern detachment.

[0117] II. Experimental Equipment and Environment Sample: Finished skis using PTFE composite film technology, which have completed step S3 shaping.

[0118] Support device: A standard slap test machine is used to fix the middle of the skis with a fastening device, so that the tip and tail of the skis are suspended in the air.

[0119] Release mechanism: A lever with a weight can clamp and release the skis, allowing them to fall freely after reaching a certain height with a 40KG weight, thus precisely controlling the hitting height.

[0120] Environment: Conducted at standard room temperature (23°C±5°C).

[0121] III. Experimental Procedure Preparation: Freeze the ski sample at room temperature / -20℃ for 4 hours, then uniformly freeze. Then place it horizontally on the test platform, ensuring it is firmly supported.

[0122] Identify and mark a test point on the tip or tail of the ski (the thinnest and most easily deformed part).

[0123] Place the pull rod of the tapping tester on the head (tail) of the test plate and suspend it directly above the test point.

[0124] Set the tapping parameters: Tapping Energy: Tapping with a 40KG weight Number of taps: According to the invention description, "15 taps" is set to 15 consecutive or intermittent impacts at the same test point or adjacent test points.

[0125] Perform the experiment: Activate the release device to allow the ski head (tail) to fall freely from a set height after being loaded with 40KG, and impact the test stand vertically.

[0126] After each tap, check the board surface (especially the impact point and surrounding area) for any visible signs of delamination, cracking, or damage.

[0127] Repeat this process until the set 15 taps are completed.

[0128] Results evaluation and recording: Post-experiment inspection: After all the tapping was completed, the skis were removed from the support frame for a detailed inspection: Macroscopic inspection: Visually inspect the impact point and surrounding area for cracks, pits, delamination, pattern bubbling or peeling, etc.

[0129] Auxiliary examination: Run your fingernail across the impact area to feel for a "rustling" sound or unevenness, to make a preliminary judgment on whether there is internal layering. For more precise testing, gently tap the area with the edge of a coin and listen to whether the sound is dull (the sound is dull at the layering point).

[0130] Acceptance standard: As described in the invention, the product is considered acceptable if it does not crack after being tapped 15 times. Specifically: The panel coating (UV varnish and transferred pattern) is free of cracks and peeling.

[0131] There are no visible delaminations or bulges between the upper fiberglass layer and the poplar wood.

[0132] The plate structure has no cracks of any kind.

[0133] IV. The Scientific Nature and Significance of the Experiment Quantitative assessment: By using fixed quality, height, and number of times, the originally subjective "tapping" behavior is transformed into a quantifiable and repeatable standardized test, making product quality control more scientific and comparable.

[0134] Targeted Verification: This experiment specifically verified the advantage claimed in this invention: "The varnish and ink directly penetrate and adhere to the glass fiber and epoxy resin...making the panel surface more scratch-resistant and crack-free." It proved that the new lamination process achieves, and may even exceed, the bonding strength of traditional panel structures.

[0135] Enhancing Credibility: Providing such specific experimental methods in patent documents or product descriptions greatly enhances the credibility and persuasiveness of the technical solution, demonstrating the product's durability to customers and consumers.

[0136] In this embodiment, an elasticity test was conducted on the skis shaped in S3, and the result was 48.7 mm.

[0137] Specifically as follows: I. Experimental Objective The elastic stiffness of a ski is quantified by measuring its deflection (bending) under a specific load. The experimental result (e.g., 48.7 mm) is a specific, comparable value used for: Quality control: Ensure consistent elasticity properties in each batch of products.

[0138] Performance rating: Provides a classification system for skiers of different skill levels (beginners need softer / easier-turning boards, while experts need stiffer / more stable boards).

[0139] Design validation: It was confirmed that the new process (using PTFE composite membrane for weight reduction) did not have a negative impact on the core mechanical properties of the skis.

[0140] II. Experimental Equipment and Environment Sample: Finished skis that have completed step S3 shaping.

[0141] Support frame: Two identical support rollers with rounded tops of ≥5mm radius. The span (L) between the two support rollers must be fixed, typically a standard value, such as 700 mm. This span simulates the distance between bindings when a skier is standing.

[0142] Pressurization device: A pressure roller located directly above the ski and parallel to the support roller.

[0143] A mechanical testing machine that can apply a vertically downward force to the center of the ski through a pressure roller, or a system of weights and levers of known mass.

[0144] The device must be equipped with force sensors and displacement sensors, capable of accurately measuring the applied force (F) and the resulting deflection (δ).

[0145] Environment: Conducted at standard room temperature (23°C ± 5°C). The skis should be left to stand in the test environment for several hours to allow their temperature to align with the ambient temperature.

[0146] III. Experimental Procedure Preparation: Place the skis horizontally with the bottom side down on the two support rollers. Ensure that the support points are located in the nose and heel areas (i.e., the simulated binding installation positions), and that the center point of the span corresponds exactly to the center of the ski's waist (narrowest part).

[0147] Align the pressure roller directly above the center point of the span.

[0148] Preloading: Apply a small preload (e.g., 10 N) to eliminate the effects of ski warping and system clearances. Zero the displacement readings in this state. This point is the reference point for all measurements.

[0149] Applying load and logging data: Begin applying pressure at a constant, slow rate.

[0150] The target load is typically a standard value, such as 300 N (approximately 30.6 kgf), which is sufficient to produce noticeable and measurable bending without causing permanent deformation.

[0151] When the load reaches the target value (e.g., 300 N), maintain the load for a short time (e.g., 10 seconds), and then record the central deflection value (δ) measured by the displacement sensor at this time. This is the key data, such as the 48.7 mm mentioned in the invention description.

[0152] A force-displacement curve can be plotted from 0N to the target load, and the slope of this curve is the stiffness of the ski.

[0153] Uninstallation and checks: Slowly unload the load.

[0154] Check that the skis have fully recovered their original shape without permanent deformation to ensure that the test was conducted within the range of elasticity.

[0155] IV. Results Analysis and Significance Data Interpretation: The larger the deflection value (δ), the more the ski bends under the same force, meaning the ski is softer. Such skis are easier to turn, have higher tolerance for error, and are more suitable for park skiing or beginners.

[0156] The smaller the deflection value (δ), the less likely the ski is to bend, meaning the stiffer the ski. Such skis have better high-speed stability, transmit power more directly, and are more suitable for racing or advanced skiers.

[0157] The specific value of 48.7 mm can be compared with competitors' products or traditionally manufactured skis under the same testing conditions, thus quantitatively proving that the new process product has met the design requirements in terms of elasticity performance.

[0158] The scientific validity and significance of the experiment: Quantitative performance: Transforming subjective "feelings of softness and hardness" into objective, repeatable physical data.

[0159] Ensuring consistency: As a quality control step on the production line, we ensure that every ski sold has the promised performance.

[0160] Supporting the invention's claims: This experimental data strongly demonstrates that although the new process eliminates the traditional panel and reduces weight, the core mechanical properties (elasticity) of the ski are maintained and optimized, dispelling users' concerns that "weight reduction may lead to a decrease in performance."

[0161] In this embodiment, a snow adhesion test was conducted on the skis shaped in S3, and the test results showed that they did not easily adhere to snow.

[0162] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
