Generally, pure wood ball boards are mostly five-layer or seven-layer structures, which are surface materials, strength materials and core materials respectively, and the seven-layer bottom plate also has secondary core materials. There are many kinds of carbon, such as hard aligned carbon, molecular carbon, medium hardness textile carbon, low carbon soft carbon and so on. Because ITTF stipulates that the natural composition of the bottom plate should reach more than 85%, so we often say that the carbon plate is still wood. Generally, adding a carbon layer between the surface material and the strength material will make the bottom plate harder and the ball speed faster. If a carbon layer is added between the strength material and the core material, the ball will eat more, and the carbon effect will occur when the force penetrates the carbon layer.

Although the carbon floor has the advantages of high strength and high speed, its disadvantages are quite obvious because of the addition of carbon. When hitting the ball, the amplitude and frequency of the vibration of the soleplate will change, and the feeling transmitted by the opponent will be unreal, so the carbon soleplate will easily make users make wrong judgments in control, leading to poor control. Because most carbon boards are very fast, if you are not used to it and the technical action is not completed, the ball will leave the board and cause mistakes. In addition, after adding carbon, the elasticity is relatively large, and the effect of hitting the ball with or without strength does not change obviously, and the short swing is easy to be introduced or run high, resulting in the opponent's opportunity ball. (Table tennis is the ultimate group player, copying the party XXX) Because of the shortcomings of carbon board, most world-class players use pure wood floors at present, especially straight players. Moreover, no straight world champion has used carbon board, only Marin has used it for a few short months, and Marin has not achieved any good results in using carbon board these months. Carbon board is suitable for old fans who need equipment help, or players who rely solely on speed and strength.
Finally, adding carbon can harden the bottom plate, but the hardness of the bottom plate does not depend on whether there is carbon or not. The most obvious examples are CL, which is called God Board, and Red Black Carbon King 7.6, which is very popular with fans. The structure of these two plates is exactly the same: lymph+Ayous+Ayous+Ayous+Ayous+Ayous+lymph, and the strength of CL (the second layer of Ayous) is much thicker than that of red and black. Although red and black are bonded with carbon glue, red and black eat the ball deeper than CL.
