A kind of amorphous alloy reinforced racket and its preparation method

Abstract

A method for preparing an amorphous alloy reinforced racket, comprising steps: step S1: connect amorphous alloy strips to both ends of the carbon cloth, one end of the amorphous alloy strip extends out of the carbon cloth by 10mm-100mm; step S2: connect the carbon cloth The cloth is rolled into a long strip, and then the extended amorphous alloy strip is wrapped around one end of the long strip of carbon cloth, and then wrapped with carbon yarn; Step S3: Make the rolled long strip of carbon cloth into the frame of the racket Initial shape; Step S4: Open a card slot in the middle of the joint between the racket shaft and the racket frame, insert the amorphous alloy sheet into the slot; Step S5: Wrap the joint between the racket shaft and the racket frame with carbon fiber cloth, and connect the racket shaft to the racket frame. The racket frame is connected to form a racket embryo, which is put into the molding mold, solidified and formed under the heating condition of 120-160°C, and after cooling, the semi-finished badminton racket that has been formed in the mold is taken out. The invention utilizes the high strength, high elasticity, high hardness, light weight and other excellent properties of the amorphous alloy material to enhance the strength of the joint between the racket frame and the racket shaft, and reduce the risk of fracture here.

Description

technical field [0001] The invention relates to the field of sports equipment, in particular to an amorphous alloy reinforced racket and a preparation method thereof. Background technique [0002] Racquets are generally connected in sequence by frame, shaft, and handle. At present, the frames and shafts of badminton rackets and tennis rackets on the market are mostly made of carbon fiber composite materials, which are composed of reinforced epoxy resin materials wrapped with carbon fiber belts. Skeleton, enhance the strength of the racket. However, in order to reduce the weight of the racket, the shaft and the frame basically adopt a hollow structure, which will reduce the stability of the connection between the shaft and the frame. When hitting the ball quickly, the connection between the shaft and the frame is prone to breakage Or distorted and deformed, thereby causing the hand, racket rod, and racket frame to be out of sync and unable to play the batting effect that the...

Problems solved by technology

However, in order to reduce the weight of the racket, the shaft and the frame basically adopt a hollow structure, which will reduce the stability of the connection between the shaft and the frame. When hitting the ball quickly, the connection between the shaft and the frame is prone to breakage Or distorted and deformed, resulting in out-of-synchronization of the hand, racket rod, and racket frame, making it impossible to hit the ball the athlete wants

[0003] Therefore, the stability of the connection between the racket shaft and the frame of the racket made of carbon fiber composite materials needs to be improved. The existing technology urgently needs to develop a racket that can ensure the stability and firmness of the racket structure. The preparation process is simple, and the use of raw materials is less. A racket that will significantly increase the weight of the racket to solve the problem that the racket is prone to breakage or asynchronous distortion at the joint between the racket shaft and the racket frame during fast hitting
