Description

Technical Field

[0001] This invention relates to the field of Peak racket manufacturing technology, specifically to Peak rackets made of one-piece molded carbon fiber composite material and their manufacturing process. Background Technology

[0002] Peakball is a relatively new ball sport that combines elements of tennis, badminton, and table tennis, and it has gained rapid popularity worldwide in recent years. Peak rackets are the core equipment of the sport, and their performance directly affects an athlete's technique and overall experience.

[0003] Currently, Peak rackets on the market are mainly made of materials such as wood, aluminum alloy, and ordinary carbon fiber. Their structures are mostly modular, meaning the racket face and handle are processed separately and then assembled by gluing or bolting. However, this modular structure suffers from problems such as poor structural stability, short lifespan, and uneven weight distribution.

[0004] To address the aforementioned technical issues, there are unibody carbon fiber composite rackets in the industry. However, the cores of existing unibody rackets mostly use a single foam core or honeycomb core structure, which makes it difficult to simultaneously achieve good shock absorption, noise reduction, and structural support performance. Summary of the Invention

[0005] The purpose of this invention is to provide a Peak racket made of integrated carbon fiber composite material and its manufacturing process. It adopts a multi-layer composite core structure with double honeycomb panels and elastic substrate, and integrates it with the carbon fiber shell through hot pressing. This achieves synergistic optimization of racket lightweighting, high strength, and shock absorption and noise reduction performance, thereby improving production efficiency and product consistency.

[0006] The above-mentioned optimized structure of the present invention is achieved through the following technical solution: a Peak racket made of one-piece molded carbon fiber composite material, including a carbon fiber shell; The racket core structure is disposed inside the carbon fiber shell and is integrally hot-pressed with the carbon fiber shell. Both the racket core structure and the carbon fiber shell include a racket face and a racket handle. The core structure includes an elastic substrate; Two honeycomb panels are symmetrically arranged on the upper and lower surfaces of the elastic substrate and fixed by adhesive bonding. An arc-shaped groove is provided on the top of the elastic substrate and the honeycomb panel; A connecting strip, wherein the connecting strip is disposed within the arc-shaped groove; A shock-absorbing arc block is disposed on the elastic substrate and the honeycomb plate at the connection between the racket face and the racket handle.

[0007] In some embodiments, the core structure further includes an elastic protrusion disposed on the connection surface between the elastic substrate and the honeycomb plate, and the honeycomb plate is pressed onto the elastic protrusion.

[0008] In some embodiments, the elastic protrusions are mesh-like structures.

[0009] In some embodiments, a nonwoven fabric layer is further included, which is disposed between the carbon fiber shell and the core structure.

[0010] In some embodiments, the honeycomb panel is made of polypropylene.

[0011] In some embodiments, the elastic substrate is made of a high-damping polymer foam material.

[0012] In some embodiments, the connecting strip and the damping arc block are made of a heat-resistant elastomer material that can maintain elasticity at the hot-pressing process temperature.

[0013] The manufacturing process of Peak rackets made of one-piece molded carbon fiber composite material includes the following steps: Step S1: Cutting raw materials; Cut elastic substrates, honeycomb panels, connecting strips, shock-absorbing arc blocks, and pre-impregnated carbon fiber cloth into specific shapes using cutting equipment; Step S2: Blank assembly; Place a honeycomb panel on the workbench, press an elastic substrate onto its surface, then press another honeycomb panel onto the elastic substrate, place a connecting strip in the arc groove, and place a shock-absorbing arc block in the corresponding position. Wrap the whole with carbon fiber cloth to initially position and connect the components, and complete the production of the blank. Step S3: Integrated hot pressing molding; The blank is placed in a hot pressing mold, and then the hot pressing mold containing the blank is placed in a hot press. The appropriate hot pressing temperature and time are set so that the carbon fiber cloth is heated and tightly connected to the core structure. Step S4: Cold pressing, shaping, and demolding; After the expected pressing time is reached, the mold is removed and transferred to a cold press without heating function to continue to apply preset pressure while cooling the mold. After the mold is cooled to room temperature, the mold is opened and demolded to remove the molded body. Step S5: Post-processing; The surface of the racket is sanded and painted. Edge protectors are wrapped around the sides of the racket face and fixed with glue. Then, grip plates and end caps are installed on the handle of the racket. Finally, grip tape is wrapped around the handle of the racket.

[0014] In some embodiments, during step S3, the hot pressing mold is evacuated.

[0015] In some embodiments, step S5 includes the following steps: Step S51: Sandblast the racket body to roughen its surface; Step S52: Grind the roughened racket body, apply a primer to its surface, and then bake it. Step S53: After the racket body has cooled to room temperature, polish it, then spray paint on the surface of the racket body, let it stand for a set time, and then bake it. Step S54: Repeat step S53 multiple times.

[0016] The above-described technical solutions in the embodiments of the present invention have at least the following technical effects or advantages: (1) The present invention adopts an integrated hot-press molding process for carbon fiber shell and core structure, which can avoid the connection seams of traditional split structure, so that the racket face and the racket handle form an integral structure without weak links. At the same time, the non-woven fabric layer enhances the bonding force between carbon fiber shell and core structure, avoids peeling, and allows carbon fiber shell and core structure to be stressed synchronously, thereby improving the overall load-bearing capacity. The elastic substrate and honeycomb plate adopt a grid-like elastic protrusion point-to-surface bonding structure, which improves the connection strength of the multi-layer structure of core and avoids delamination.

[0017] (2) The present invention adopts a multi-layer composite core structure of double honeycomb plate and elastic substrate, and is integrally hot-pressed with carbon fiber shell. When hitting the ball, the impact force of the ball and the racket first acts on the carbon fiber shell. The core structure is stressed. The elastic substrate absorbs most of the vibration energy and noise through its own deformation. The honeycomb structure of the honeycomb plate can further disperse the vibration through the small deformation of the hole wall. The connecting strip in the arc groove absorbs local vibration through elastic compression, avoiding the vibration from concentrating in the central area of ​​the racket face. The shock-absorbing arc block prevents the vibration from being transmitted to the handle, reducing the impact of vibration on the athlete's wrist and arm. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0025] refer to Figure 1-6 The Peak racket is a one-piece molded carbon fiber composite material, comprising a carbon fiber shell 1 and a core structure 2. The core structure 2 is located inside the carbon fiber shell 1 and is integrally hot-pressed with the shell. Both the core structure 2 and the carbon fiber shell 1 include a connected racket face and a handle, which are integrated structures without obvious seams, thus improving the overall strength of the racket and extending its service life. The carbon fiber shell 1 can be made by impregnating T700 grade carbon fiber cloth with resin and then hot-pressing it, ensuring that the carbon fiber shell 1 is lightweight while possessing excellent tensile strength and bending stiffness.

[0026] The core structure 2 is a multi-layered composite structure, including an elastic base plate 21, two honeycomb plates 22, an arc groove 23, a connecting strip 24, and a shock-absorbing arc block 25. The elastic base plate 21 has good elasticity and sound absorption properties, effectively absorbing vibrations and noise generated during the shot. The shape of the elastic base plate 21 is adapted to the inner cavity contour of the carbon fiber shell 1, covering the entire inner cavity area of ​​the racket face and handle. The two honeycomb plates 22 are symmetrically arranged on the upper and lower surfaces of the elastic base plate 21 and can be bonded and fixed with epoxy resin to achieve pre-connection during the blank manufacturing process. The honeycomb plates 22 can be made of polypropylene, which is lightweight, high-strength, and impact-resistant. The honeycomb holes can be a regular hexagonal structure, which can disperse and withstand the impact pressure through its own geometric properties, improving the support strength of the core structure 2. The total thickness of the two honeycomb plates 22 after bonding with the elastic base plate 21 matches the inner cavity height of the carbon fiber shell 1, ensuring a tight fit between the core structure 2 and the carbon fiber shell 1. An arc-shaped groove 23 is located on top of the elastic substrate 21 and the honeycomb plate 22, specifically in the central area of ​​the racket face. The cross-section of the arc-shaped groove 23 can be semi-circular. The arc-shaped groove 23 can increase the elastic deformation space of the racket face without affecting the strength of the racket core structure 2, thereby improving the rebound force of the shot and reducing stress concentration during the shot. A connecting strip 24 is located inside the arc-shaped groove 23. The shape of the connecting strip 24 is adapted to the inner cavity of the arc-shaped groove 23. The connecting strip 24 is fixedly connected to the inner wall of the arc-shaped groove 23 by epoxy resin. Its function is to fill the internal space of the arc-shaped groove 23, and at the same time, it uses its own elastic properties to further improve the shock absorption effect of the racket face, avoiding abnormal sound caused by air cavities in the arc-shaped groove 23. A shock-absorbing arc block 25 is disposed at the connection between the racket face and the handle of the elastic base plate 21 and the honeycomb plate 22, respectively. The cross-section of the shock-absorbing arc block 25 can be fan-shaped, and its thickness is the same as the thickness of the racket core structure 2. Since the connection between the racket face and the handle is a stress concentration area, the installation of the shock-absorbing arc block 25 can effectively disperse the hitting stress in this area. It can be fixedly connected to the elastic base plate 21 and the honeycomb plate 22 with epoxy resin adhesive, covering the entire transition area at the connection between the racket face and the handle.

[0027] Furthermore, the core structure 2 also includes an elastic protrusion 26, which is disposed on the connection surface between the elastic substrate 21 and the honeycomb panel 22, and the honeycomb panel 22 is pressed onto the elastic protrusion 26. The elastic protrusion 26 and the elastic substrate 21 are integrally formed structures made of the same material. The setting of the elastic protrusion 26 can increase the contact area between the elastic substrate 21 and the honeycomb panel 22, and at the same time form a point-to-surface bonding structure during the bonding process, thereby improving the bonding strength between the two and avoiding delamination during the integral hot pressing process or during use.

[0028] Preferably, the elastic protrusion 26 can be a mesh structure, and the height of the elastic protrusion 26 can be 1-2mm. The mesh structure of the elastic protrusion 26 can further improve the connection stability between the elastic substrate 21 and the honeycomb plate 22. At the same time, the mesh gap can provide space for excess glue during the bonding process, avoid the unevenness of the bonding surface caused by glue accumulation, and ensure the overall flatness of the racket core structure 2. Meanwhile, the mesh gap can delay the propagation of noise and vibration energy, reduce the loss of ball energy rebound, and improve the ball rebound force.

[0029] Furthermore, the Peak racket also includes a non-woven fabric layer 3, which is located between the carbon fiber shell 1 and the core structure 2. The non-woven fabric layer 3 can be made of polyester non-woven fabric with a thickness of 0.2-0.5mm. The non-woven fabric layer 3 can be fixedly connected to the inner wall of the carbon fiber shell 1 and the outer surface of the core structure 2 respectively by epoxy resin adhesive, which can improve the bonding force between the carbon fiber shell 1 and the core structure 2. The interwoven fiber structure of the non-woven fabric enhances the interfacial adhesion. At the same time, the non-woven fabric has a certain elasticity and shock absorption performance, which can further optimize the shock absorption effect of the racket.

[0030] In some embodiments, the elastic substrate 21 may be made of a high-damping polymer foam material, specifically polyurethane foam, which has elastic properties and is also a porous sound-absorbing material. After sound waves enter the pores, they rub against the pore walls, converting sound energy into heat energy, thereby achieving a sound-absorbing effect.

[0031] In some embodiments, the connecting strip 24 and the shock-absorbing arc block 25 are made of a heat-resistant elastomer material that can maintain elasticity at the hot-pressing process temperature, specifically a sponge made of silicone rubber foam.

[0032] The manufacturing process of Peak rackets made of one-piece molded carbon fiber composite material includes the following steps: Step S1: Raw material preparation and cutting First, based on the design dimensions and structural requirements of the racket, specific shapes of the elastic substrate 21, honeycomb plate 22, connecting strip 24, shock-absorbing arc block 25, and non-woven fabric layer 3 are cut using CNC cutting equipment. Among them, the carbon fiber cloth needs to be pre-impregnated by immersing it in epoxy resin for 30-60 minutes to ensure that the resin penetrates evenly into the fiber gaps of the carbon fiber cloth. After impregnation, it is taken out and excess resin is removed by extrusion equipment to control the resin content. Then, it is cut into a size that matches the shape of the racket for later use.

[0033] Step S2: Blank assembly Place a cut honeycomb panel 22 on a clean workbench and evenly coat its surface with epoxy resin adhesive. The adhesive thickness can be 0.1-0.2 mm. Then, align the elastic substrate 21 and place it on the coated surface of the honeycomb panel 22, and gently press it to initially bond the elastic substrate 21 and the honeycomb panel 22 together. Next, evenly coat the other surface of the elastic substrate 21 with epoxy resin adhesive, and then align and press another honeycomb panel 22 onto the elastic substrate 21, forming a three-layer core substrate structure consisting of the honeycomb panel 22, the elastic substrate 21, and the honeycomb panel 22.

[0034] Then, epoxy resin is applied to the arc-shaped groove 23 of the core substrate structure, and the connecting strip 24 is embedded into the arc-shaped groove 23 and pressed to fix it. Epoxy resin is applied to the connection between the racket face and the handle, and the shock-absorbing arc block 25 is pasted in the corresponding position and pressed to fix it. Subsequently, a layer of epoxy resin is evenly applied to the outer surface of the core substrate structure, and the non-woven fabric layer 3 is wrapped around the outer surface of the core substrate structure, ensuring that the non-woven fabric layer 3 is tightly bonded to the core substrate structure without bubbles or wrinkles.

[0035] Finally, the pre-impregnated carbon fiber cloth is wrapped around the core, which is covered with non-woven fabric layer 3, to initially position and connect the components, thus completing the fabrication of the blank.

[0036] Step S3: Integrated hot pressing molding The assembled blank is placed in a custom-made thermoforming mold. Before placement, release oil is sprayed onto the inner wall of the mold to facilitate subsequent demolding. Then, the thermoforming mold containing the blank is placed in a hot press. First, the mold is closed, and a vacuum treatment is performed on the thermoforming mold. The vacuum degree is controlled between -0.09 and -0.1 MPa, and the vacuuming time is 10-15 minutes to ensure that the air in the mold and the air between the blank layers are fully expelled, avoiding air bubbles and delamination defects in the molded product.

[0037] After vacuuming is completed, the hot press is started to heat and pressurize. The hot pressing temperature is set to 130-150℃, and the heating rate is 5-8℃ / min. When the temperature reaches the set temperature, it is kept constant while pressure is applied at a value of 2-3MPa. The constant temperature and pressure time is 60-90 minutes to fully cure the epoxy resin in the carbon fiber cloth and tightly connect it with the core structure 2 and the non-woven fabric layer 3 to form an integrated structure.

[0038] Step S4: Cold pressing, shaping, and demolding After the expected pressing time is reached, the mold is removed from the hot press and immediately transferred to a cold press without heating. A preset pressure is continuously applied, the same as the hot pressing pressure (2-3 MPa), while the mold is cooled. Cooling can be achieved using circulating water cooling at 5-10℃ for 40-60 minutes, allowing the mold temperature to drop to room temperature. The cold pressing process effectively eliminates internal thermal stress in the product, preventing deformation caused by uneven shrinkage during cooling, and improving dimensional accuracy and structural stability.

[0039] After the mold cools to room temperature, turn on the cold press, remove the mold, demold, and take out the molded piece.

[0040] Step S5: Post-processing The surface of the racket is sanded and painted. Edge protectors are wrapped around the sides of the racket face and fixed with glue. Then, grip plates and end caps are installed on the handle of the racket. Finally, grip tape is wrapped around the handle of the racket.

[0041] In some embodiments, step S5 includes the following steps: Step S51: Surface roughening treatment The outer surface of the racket body is sandblasted using quartz sand as the blasting medium. The sand particle diameter is 0.1-0.3 mm, the blasting pressure is 0.3-0.5 MPa, the blasting distance is 15-20 cm, and the blasting time is 3-5 minutes. Sandblasting removes impurities and oxide layers from the racket body surface, roughens the surface, and improves the adhesion of subsequent coatings. After sandblasting, compressed air is used to blow away the sand particles and dust from the racket body surface.

[0042] Step S52: Coating and Baking The roughened racket body is sanded to remove burrs and protrusions, making the surface smooth. After sanding, a layer of primer is evenly applied to the surface, specifically epoxy composite material putty, with a coating thickness of 0.2-0.3mm. This fills the tiny pores on the racket body surface and improves surface smoothness. After coating, the racket body is placed in an oven for baking at 80-100℃ for 30-40 minutes to allow the loess coating to dry and harden.

[0043] Step S53: Sanding and painting / baking After the racket body has cooled to room temperature, sand the surface of the primer coating to remove excess primer and achieve a mirror-like finish. After sanding, remove dust from the racket body surface, then apply paint using electrostatic spraying to a thickness of 0.1-0.2 mm. After spraying, allow it to stand for 10-15 minutes to allow the paint to level, then place the racket body in an oven to bake at 120-140℃ for 40-60 minutes to cure the paint layer.

[0044] Step S54: Repeat the painting and baking process Repeat step S53 multiple times, preferably four times. Before each coat of paint, the previous layer should be lightly sanded to ensure adhesion between paint layers. After multiple coats and baking, a paint layer with uniform thickness, smooth surface, and strong adhesion can be formed, improving the product's appearance and wear resistance. The paints applied in the earlier coats can be polyurethane topcoats to improve the smoothness of the racket surface. The final coat can be a granular paint to increase the friction between the racket and the ball.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
