Ping-pong racket
专利汇可以提供Ping-pong racket专利检索，专利查询，专利分析的服务。并且PURPOSE: To sufficiently and effectively display the respective characteristic of a ligneous plate and a carbon fiber sheet, whichever one of single plate or laminated plate is used as the ligneous plate, by connecting a sheet, using a material of carbon fiber in thin thickness of predetermined proportion to the thickness of a racket main total unit, to be arranged and forming a ping- pong racket.
CONSTITUTION: Layer plates 10, 10' of equal thickness, forming a racket main unit, interpose over the total surface in a thickness direction central part a sheet 11, using a material of carbon fiber in predetermined thickness, to be integrally connected by an adhesive agent, and a numeral 12 is a grip. The sheet 11, using the material of carbon fiber, is formed into a crossed shape by knitting the carbon fiber or into a sheet shape by impregnating this cross shape with epoxy resin or the like, that is, using carbon fiber reinforced plastic used as the composite material. While the sheet 11, using the material of this carbon fiber, uses a material of about 0.1 to 0.5mm thickness and the material formed in this thickness by piling one or two or more sheets. And the material is used forming a racket main total unit to about 6 to 10mm thickness including the sheet 11 using the material of this carbon fiber.
