Embodiment

[0032] image 3 A block diagram showing how a tennis racket is made, such as image 3 Shown, the tennis racket manufacturing method comprises the following steps:

[0033] A. The forming process of the outer frame. In this process, the fiber prepreg is first folded into a solid strip, and then the solid strip is bent into the shape of a tennis racket to obtain a prefabricated body of the outer frame 1. The prefabricated body of the outer frame 1 That is to say, it includes the big racket frame 2, the bifurcation part 4 and the joint part 5 (outer frame forming process: A1);

[0034] B. The forming process of the small frame, in which the fiber prepreg is folded into a solid strip to obtain the prefabricated body of the small frame 3, and then the prefabricated body of the small frame 3 is put into a mold to be heated and heated in the small frame Apply pressure to the outer surface of the prefabricated body of the frame 3, so that the prefabricated body of the small racket f...

Abstract

The invention discloses a tennis racket and a manufacturing method thereof. The tennis racket includes a frame body, an outer framework, a large racket frame, a small racket frame, a furcation part, acombined part, a reinforced layer and a racket handle. The outer framework is composed of the large racket frame, the furcation part, the combined part and the reinforced layer, and the outer framework and the small racket frame are manufactured by means of an external pressurizing and forming manufacturing method. According to the external pressurizing and forming manufacturing method, the surfaces of the outer framework and small racket frame are pressurized; since a cavity required in an internal pressurizing and forming method is omitted, the solid tennis racket can be manufactured and islower in thickness, the resistance during swinging of the racket is reduced, and the ball hitting power is greater.

Description

technical field [0001] The invention relates to the related technical field of tennis rackets, in particular to a tennis racket with a solid fiber composite material structure and a manufacturing method thereof. Background technique [0002] At present, in the existing known technology, there are two manufacturing methods of fiber composite tennis rackets, one is the internal pressure molding method of nylon air duct, and the other is the internal pressure molding method of foam material. The principles of the two manufacturing methods are The same, they are all pressurized inside the frame of the tennis racket to force the fiber prepreg made of the frame to expand and solidify from the inside to the outside along the molding surface of the mold. The tennis rackets produced by the two methods are both It is made of a tubular frame, and its cross section is a ring structure formed by fiber composite materials, and the internal cavity has the residue of nylon air duct after cu...
