Detailed Description

In order that the invention may be more fully understood, reference will now be made to the following description. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

Referring to fig. 1 to 2, a multi-layer composite pick-up racket 100 according to a first preferred embodiment of the present invention includes a racket plate 10 and a racket handle 20, the racket handle 20 is connected to the racket plate 10, a composite inner core layer 30 is disposed inside the racket plate 10, the composite inner core layer 30 at least includes a first inner core layer 31 and a second inner core layer 32, the first inner core layer 31 is bonded to the second inner core layer 32, and the first inner core layer 31 and the second inner core layer 32 are both provided with a honeycomb structure.

In this embodiment, the first inner core layer 31 is bonded by a film to realize the bonding and fixing of the second inner core layer 32; in other embodiments, the first inner core layer 31 may be coated with epoxy glue, so as to achieve the adhesive fixation of the first inner core layer 31 and the second inner core layer 32. It should be understood that the bonding manner of the first inner core layer 31 and the second inner core layer 32 is not limited too much, and it should be ensured that the first inner core layer can be tightly connected to the second inner core layer, so as to avoid the composite inner core layer 30 from loosening during use.

Further, the material of the first inner core layer 31 includes one of aramid fiber, polypropylene, aluminum alloy, and polymethacrylimide foam, the material of the second inner core layer 32 includes one of aramid fiber, polypropylene, aluminum alloy, and polymethacrylimide foam, and the material of the first inner core layer 31 is different from the material of the second inner core layer 32 to form the composite inner core layer, so as to ensure that the composite inner core layer contains different inner core materials to generate different striking effects. Among them, polymethacrylimide foam (PMI) is a cross-linked foam with uniform pore size distribution, and has excellent structural stability and high mechanical strength; correspondingly, the PMI honeycomb has good durability and environmental resistance.

In the embodiment, the first inner core layer 31 is made of aramid fiber to form an aramid honeycomb structure, and the second inner core layer 32 is made of polypropylene to form a polypropylene honeycomb structure. Specifically, the length of the side of the aramid fiber honeycomb 33 is 1.8mm or 2mm, wherein the aramid fiber honeycomb 33 is made of a hard material and is small in size, and the manufactured racket has loud hitting sound and hard hardness; the diameter and length of the polypropylene honeycomb 34 are 6mm or 8mm, wherein the polypropylene honeycomb 34 is softer and the honeycomb holes are larger, and the manufactured racket has heavier hitting sound, weaker strength and softer hardness.
