In the sport of badminton, the wear and tear of the racket is not simply due to overuse, but mainly due to its high-speed friction with fine dust particles, especially on outdoor hard and dry surfaces where the "frosted cloth effect" exacerbates wear and tear. The reasons for wear and tear are much more complex than 'overuse'. Although Pick rackets are made of hollow plastic, when combined with dust, they seem to turn into "flying sandpaper". Especially on outdoor hard or dry surfaces, the tiny dust particles carried by the sphere collide with the surface at an extremely fast speed, forming the so-called "frosted cloth effect". Experimental results have shown that each stroke causes a loss of 0.01 millimeters in the carbon fiber surface coating, and after hundreds of strokes, the racket's control performance will decrease by 15%. In addition, the sediment concentration near the non interception area is three times higher than that of the normal area due to frequent ground contact, which has also become a severely worn area.
