Detailed Description
Referring to fig. 1 and 2, which show the specific structure of the first preferred embodiment of the present invention, this embodiment discloses a method for manufacturing a frame of a tennis racket, which includes the following steps:
(1) forming and hardening an inner frame member 10, wherein the inner frame member 10 is of a hollow structure, the outer surface of the inner frame member 10 is concave and convex, a groove 11 is formed on the outer wall surface of the inner frame member 10, and a reinforcing rib 12 is formed on the inner wall surface of the inner frame member 10; in this embodiment, the inner side surface and the upper and lower side surfaces of the outer wall surface of the inner frame 10 are both recessed with the grooves 11, correspondingly, the inner wall surface of the inner frame 10 is formed with the reinforcing ribs 12, and the cross section of the reinforcing ribs 12 is triangular, so that the structural strength is very good; the inner frame 10 is a metal member, a carbon fiber member, or a composite member of carbon fiber and a foam material, but not limited thereto. And the reinforcing ribs 12 at various positions on the inner frame member 10 have different directions or numbers, and the reinforcing ribs 12 may have foamed material or no foamed material therein.
(2) Carbon fiber cloth is laid in the groove 11 and completely covers the outer surface of the inner frame member 10.
