Abstract
The present disclosure proposes a pickleball paddle with a foam core vortex-shaped linear structure and a preparation method thereof, comprising a base plate and an inner core mounted on the base plate. The inner core comprises: a core layer; a wrapping layer wrapping around exterior of the core layer; a buffer layer, which is located on one side of the wrapping layer. Wherein, the exterior of the core layer is coated with the wrapping layer, and they form an elongated structure.

A pickleball paddle with a foam core vortex-shaped linear structure, comprising a base plate (1) and an inner core mounted on the base plate (1), the inner core comprising:
- a core layer (3) made of a Polyurethane (PU) foam material;
- a wrapping layer (4) made of a carbon fiber material, the wrapping layer (4) wrapping around an exterior of the core layer (3);
- and
- a buffer layer (5) made of an Ethylene Vinyl Acetate Copolymer (EVA) material and located on one side of the wrapping layer (4),
- wherein the wrapping layer (4) is coated on the exterior of the core layer (3) to form an elongated structure;
- and the elongated structure is rolled with the buffer layer (5) to form an inner core of the foam core vortex-shaped linear structure.
A preparation method of a pickleball paddle with a foam core vortex-shaped linear structure, the preparation method comprising:
- preparing materials by preparing a Polyurethane (PU) foam material as a core layer (3), a carbon fiber material as a wrapping layer (4), and an Ethylene Vinyl Acetate Copolymer (EVA) material as a buffer layer (5);
- fabricating an inner core by coating an exterior of the core layer (3) with the wrapping layer (4) so that the core layer (3) and the wrapping layer (4) form an elongated structure, rolling the elongated structure with the buffer layer to form the vortex-shaped linear structure, thereby forming the inner core;
- fabricating a base plate by providing a polypropylene honeycomb plate, making a mounting hole (101) at a middle portion of the honeycomb plate, mounting the inner core in the mounting hole (101) by hot pressing, and pressing the inner core flat;
- mounting panels (2), a handle (7), and an edge cover (6) to the base plate by pasting the base plate (1) between two panels (2) with glue, thereby forming a first combined entity;
- fixing and sleeving the edge cover (6) onto an outer edge of the first combined entity, thereby forming a second combined entity;
- fixing and sleeving the handle (7) onto one end of the second combined entity by fixing and sleeving the handle (7) onto one end of the edge cover (6), one end of the two panels (2), and one end of the base plate (1) simultaneously, thereby forming a prototype of the pickleball paddle;
- placing prototype of the pickleball paddle into a mold, and performing pressure curing in a high-temperature environment until the inner core, the panels (2), the handle (7), and the edge cover (6) bind with the base plate (1);
- and
- removing the prototype of the pickleball paddle from the mold, and performing thorough cooling.
