[0002] The table tennis rackets currently on the market are mainly solid wood rackets and carbon fiber rackets. The density of solid wood rackets is uneven due to the annual rings of wood, and the force response speed in each direction is slightly different, so that its elasticity is different. It is not determined by the way the athlete hits, there is a certain chance, even if the density of the composite board is as uniform as possible in all directions, there are still differences, and the cost of carbon fiber is too high, and imports are restricted; so a new type is needed Substitute products to meet market demand

Abstract
The invention discloses a novel table tennis racket base plate which comprises a racket body, wherein the racket body comprises a core board layer and a panel layer; the upper surface and the lower surface of the core board layer are glued through a modified glutinous rice glue layer and the panel layer separately; the core board layer is made of a composite material sheet and the thickness is 3-5mm; the panel layer is made of a bamboo board and the thickness is 0.5-1mm; and the modified glutinous rice glue layer is made of modified glutinous rice glue and the thickness is 0.3-0.8mm. The novel table tennis racket base plate is uniform in density and equal in force reaction rates in various directions, has relatively high stability, high strength and sufficient toughness and has multiple excellent properties, such as electrical insulating property, corrosion resistance, combustion resistance and high-temperature resistance, the service life of a table tennis racket is prolonged, and meanwhile, the production cost is relatively low.
