Problems solved by technology

At present, the common repair method on the market is to plug the metal rod inside the racket. The main disadvantage of this method is that the weight increases a lot. The weight of the repaired tennis racket increases by 20-30 grams, which seriously damages the original balance point of the racket; , the process of using a metal rod to repair a tennis racket is more difficult, because the frame of the tennis racket is relatively strong, and it is easy to cause other parts to break when the fracture is moved

Embodiment 1

[0016] Embodiment 1, a broken tennis racket is repaired, at first the original paint on both sides of the racket fracture is removed and the carbon fiber debris, plastic film, and dust particles in the fracture are scraped clean; then a section of 7 cm long The carbon fiber tube (0.6 cm in diameter, sealed at both ends, containing 0.5 g of polyvinyl chloride resin powder) is flattened and placed inside the fracture of the tennis racket, evenly distributed on both sides of the fracture; a small section of carbon fiber welding strip is tightly wound on the The outer periphery of the fracture of the tennis racket is heated to a temperature of 150°C; after 30 minutes, it is fused with the fracture of the racket; the welding joint is properly polished and painted.

Embodiment 2

[0017] Embodiment 2, a broken tennis racket is repaired, at first the original paint on both sides of the racket fracture is removed and the carbon fiber debris, plastic film, and dust particles in the fracture are scraped clean; then a section of 6 cm long The carbon fiber tube (0.7 cm in diameter, sealed at both ends, containing 0.6 g of polyvinyl chloride resin powder) is flattened and placed inside the fracture of the tennis racket, evenly distributed on both sides of the fracture; cut a small section of carbon fiber welding strips and wrap it tightly on the tennis racket Take the outer periphery of the racket and heat it to a temperature of 170°C; wait for it to fuse with the racket fracture after 25 minutes; properly polish the welding joint and paint it.

Embodiment 3

[0018] Embodiment 3, a broken tennis racket is repaired, at first the original paint on both sides of the racket fracture is removed and the carbon fiber residue, plastic film, and dust particles in the fracture are scraped clean; then a section of 6 cm long The carbon fiber tube (0.65 cm in diameter, sealed at both ends, containing 0.5 g of polyvinyl chloride resin powder) is flattened and placed inside the fracture of the tennis racket, evenly distributed on both sides of the fracture; a small section of carbon fiber welding strip is tightly wound on the tennis racket Take the outer periphery of the racket and heat it to a temperature of 180°C; wait for it to fuse with the racket fracture after 20 minutes; properly polish the welding joint and paint it.

Abstract

The invention discloses a method used for repairing a carbon badminton racket. The method used for repairing the carbon badminton racket is characterized by comprising the following steps: firstly, cleaning a racket fracture; mixing the carbon fibre and the epoxy resin and then paving the carbon fibre and the epoxy resin into the shape of sheet; then rolling the carbon fibre to be a carbon fibre cylinder, wherein the diameter of the carbon fibre cylinder is slightly smaller than an inner cavity of a racket fracture; cutting a segment of carbon fire cylinder with the length of 6-7cm; adding 0.5-1.0g of polrvinyl chloride resin powder in the cylinder, sealing two end openings of the carbon fibre cylinder by using carbon fibre sheets, and then pressing the carbon fibre cylinder flatly, plugging carbon fibre sheets into the racket fracture and averagely distributing carbon fibre sheets on both sides of the fracture; continuously heating for 20-30 minutes to fuse with the racket fracture; properly polishing the welding opening and then painting. By adoption of the technical solution of the invention, the process of repairing the carbon badminton racket becomes simple and easy; very little integrative weight of the repaired badminton racket is added (generally only 5-8g is added), the intensity reaches 65 ponds; the tension force, the hand feeling, and the appearance of the original badminton racket are kept completely.

Description

technical field [0001] The invention relates to a method for repairing sports equipment, in particular to a method for repairing a carbon tennis racket. technical background [0002] At present, more and more people like sports, among which tennis is more popular among the people. The ensuing problem is that when the racket accidentally hits the ground or the rackets collide with each other, it will cause the racket to be damaged or even broken so that it cannot be used again. If you buy a new one, it's expensive. Therefore, fans mostly choose to use the racket after repairing it. At present, the common repair method in the market is to plug the metal rod inside the racket. The main disadvantage of this method is that the weight increases a lot. The weight of the repaired tennis racket increases by 20-30 grams, which seriously damages the original balance point of the racket; , the process of using metal rods to repair a tennis racket is more difficult, because the frame ...
