Background

With the vigorous development of sports career, baseball as a sports item attracts many enthusiasts due to its characteristics of high skill and strong stimulation. In baseball, a baseball bat is a tool for a user to swing a high-speed ball, so that a good baseball bat must have the advantages of light weight, high rigidity, good elasticity, good shock absorption capability, and the like, and the surface of the baseball bat must also be able to bear the huge impact force of a high-speed ball at a moment.

Currently, baseball bats used in baseball games can be broadly classified into three major categories, namely, wooden baseball bats, metallic baseball bats, and fibrous baseball bats. Among them, the wooden baseball bat is the most cheap and thus popular, however, it has several disadvantages: firstly, the wooden baseball bat is solid, has heavier overall weight, has a gravity center leaning against the head end of the hitting part, and has poor balance, so that the wooden baseball bat is more laboured and has slower swinging speed when in use, and the hit baseball is not strong and has short flying distance; secondly, the structure of the wooden baseball bat is fragile, and is easy to crack and even break, but the batting feel is very comfortable, and the wooden baseball bat cannot generate violent vibration and stabbing pain. Metal baseball bats, such as aluminum baseball bats, which are generally hollow structures, are lighter in weight and more desirable in balance point, so that the batting performance is better, and the aluminum baseball bats are more durable than wood baseball bats, so that the bats account for over 70% of the market; however, the aluminum rod causes problems of severe vibration and stabbing pain of hands when hitting a ball.
