Technical Field

[0001] The invention relates to the technical field of racket production, in particular to a high-strength racket and a production process thereof. Background Art

[0002] Pickleball is a sport in which a ball is hit with a racket. It originated from Benbridge Island in Seattle, USA. It can be said to be a combination of tennis, badminton and table tennis. The amount of activity and exercise is less than tennis, and it is suitable for people of all ages. Therefore, it has gradually become popular in recent years and is loved by the public.

[0003] In the past, pickleball rackets were made with a sandwich structure of PP core and aramid core. Due to the sandwich design, adhesive was needed for bonding. The middle area of ​​the racket body is often used to hit the ball. The middle area is the sweetheart area for hitting the ball, so the sweetheart area is often subjected to impact force. Long-term impact will cause the adhesive to fall off. In addition, the strength of the PP core and aramid core is insufficient, which causes the middle area to collapse and the durability to decrease, resulting in a decrease in the elasticity of the racket and a poor hitting effect.

[0004] Therefore, it is necessary to propose a high-strength racket and its production process to improve the overall strength of the racket, thereby ensuring that the racket is of appropriate weight and also improving the durability of the racket, and maintaining the elastic performance of the racket for a long time.
