[0002] During the manufacturing process of the soles, in order to enhance the toughness and strength of the soles, a carbon plate is usually added to the soles of some shoes such as basketball shoes or running shoes. The carbon plate is a composite material formed by bonding epoxy resin and carbon fiber filaments. The carbon plate has the advantages of light weight, good toughness and good strength. The basketball shoes or running shoes made from it have high elasticity and extend their service life. At the same time, the soles will not deform under high exercise volume.
