Description

Technical Field

[0001] This utility model relates to the field of Peak racket technology, and in particular to Peak rackets with an integral hot-pressed hexagonal carbon fiber composite material and an aramid core. Background Technology

[0002] Conventional Peak rackets in the existing technology are made by cold-pressing and bonding wood or PP honeycomb core with fiber, followed by carving and processing, and then assembling the handle, frame, side strips, handle pads, tail cap, etc., or by hot-pressing and molding a one-piece racket. The racket frame is generally rounded, which makes it inconvenient to use. Therefore, we propose a Peak racket with a one-piece hot-pressed hexagonal carbon fiber composite material and aramid inner core to solve the above-mentioned problems. Utility Model Content

[0003] Based on the technical problems existing in the background technology, this application proposes a Peak racket with an integral hot-pressed hexagonal carbon fiber composite material and an aramid inner core.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A Peak racket with an integrally thermoformed hexagonal carbon fiber composite material and aramid core includes a base layer. The top and bottom of the base layer are bonded with an outer layer and an adhesive layer. An auxiliary layer is attached to the outer wall of both the base layer and the outer layer. A connecting layer is attached to the outer wall of the auxiliary layer. A surface layer is attached to the outer wall of the connecting layer. The racket body is composed of the base layer, outer layer, surface layer, auxiliary layer, connecting layer, and adhesive layer.

[0006] In a preferred embodiment of this utility model, the base layer is made of aramid honeycomb core material, and the outer layer is made of carbon fiber material.

[0007] In a preferred embodiment of this utility model, the auxiliary layer is made of carbon fiber with an angle of 45 degrees, the connecting layer is made of K-FAWG / ㎡ material, and the surface layer is made of K carbon fiber material.

[0008] In a preferred embodiment of this invention, the bonding layer is made of T-carbon fiber.

[0009] This racket uses an aramid honeycomb core and carbon fiber composite material, which are hot-pressed into one piece. The frameless one-piece tail cap design improves the strength of the racket face, reduces the weight, and increases the sweet spot. The aramid honeycomb core has excellent resistance to damp heat and improves the racket's shear strength and modulus. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Example

[0016] Reference Figures 1-3 The Peak racket, which is integrally hot-pressed into a hexagonal carbon fiber composite material and an aramid inner core, includes a base layer 2. The top and bottom of the base layer 2 are bonded with an outer layer 3 and an adhesive layer 6. The outer walls of the base layer 2 and the outer layer 3 are bonded with an auxiliary layer 4. The outer wall of the auxiliary layer 4 is bonded with a connecting layer 5. The outer wall of the connecting layer 5 is bonded with a surface layer 7. The racket body 1 is composed of the base layer 2, the outer layer 3, the surface layer 7, the auxiliary layer 4, the connecting layer 5, and the adhesive layer 6.

[0017] As a preferred embodiment of this utility model, the base layer 2 is made of aramid honeycomb core material, and the outer layer 3 is made of carbon fiber material.

[0018] As a preferred embodiment of this utility model, the auxiliary layer 4 is made of carbon fiber with an angle of 45 degrees, the connecting layer 5 is made of 3K-FAW200G / ㎡ material, and the surface layer 7 is made of 3K carbon fiber material.

[0019] As a preferred embodiment of this utility model, the bonding layer 6 is made of T700 carbon fiber.

[0020] The working principle of this utility model is as follows: During manufacturing, the base layer 2 of the racket shape is first cut to the appropriate size. The base layer 2 and the outer layer 3 are bonded with epoxy resin 200G / ㎡ film, and the base layer 2 is covered by the outer layer 3. The frame of the base layer 2 and the outer layer 3 is placed in 316 epoxy foam and tightly attached to the auxiliary layer 4. Then, the outer frame of the auxiliary layer 4 is covered with 3K-FAW 200G / ㎡ material, with a size of 800*40. Then, the surface layer 7 is attached to the surface of the auxiliary layer 4 again. Finally, the bonding layer 6 is attached to the handle for reinforcement to maximize the overall strength of the racket body 1. The product information label is attached, and the racket is placed in the mold cavity. After the upper and lower molds are closed, the racket is placed in a high-temperature hot press oven and heated to cure at a hot pressing temperature of 135℃±5℃ for 40 minutes. Then, the racket is placed in a cooling machine and cooled to a temperature of 10℃±5℃. The product is then removed. After sanding, trimming, applying epoxy primer, labeling, and assembly, the finished product is complete. The hexagonal racket improves ball stability. The main advantage of the hexagonal racket is the increased sweet spot, i.e., the effective hitting area. Data shows that the hexagonal racket blade surface increases the hitting area by 5% compared to traditional rackets, but the sweet spot increases by 11%, and for penhold rackets by 9%. This means that players can hit the ball with more power and a better feel when attacking. The handle also adopts an equidistant octagonal design, molded in one piece, eliminating the need for a back cover. The equidistant octagonal grip can better distribute hand pressure and reduce fatigue. The octagonal shape of the handle is more in line with the ergonomic principles of the hand, better adapting to the shape and force of the hand, allowing the palm to be more naturally fixed on the grip, improving grip stability and safety.

[0021] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
