Embodiment Construction

[0099] figure 1 A conventional graphite fiber racquet frame 11 is shown in the current and desired racquet shape. When using the manufacturing technique of air-infused graphite fibers, its weight ratio is more advantageous than previous wooden racquets. The racket frame 11 consists of a racket head 12, a shaft 13, a handle or handle 14, and a bandage 14 wrapped around the handle. These parts of the racket frame 11 are all as independent entities, but are inseparable and continuous components. The two ends 13 of the racket shaft are connected with the racket head 12 and the handle 14 . A bar or yoke portion 16 is interposed between the ends 13 of the shaft. The yoke portion 16 and the head portion 12 form a generally elliptical line around the racquet face 18 . The crimping head 19 is recessed on the outer surface of the racket head portion 12 .

[0100] figure 2 A prior art tennis racquet frame structure is shown, as described in US Patent No. 4,129,634 to Cecka. Here,...

Abstract

The inventive fiber manufacturing process is particularly adapted for demanding applications such as sports racquets, including tennis racquets, badminton racquets and other sports applications. Because of the improved strength to weight ratio of components formed using the inventive method, a wide range of flexibility is achieved, allowing use of the inventive process to manufacture, for example, a fiber reinforced (for example, graphite) modular sports racquet, optionally provided with user- selectable weights and/ or handle replacements. From the standpoint of the player, this allows a racquet frame featuring self customization. From the standpoint of a retailer, the benefit provided is reduction of inventory.; The inventive fiber, for example graphite fiber) racquet frame is filled with a plastic foam and is formed using, for example, microencapsulation technology to time, generate and apply the pressure used to form the graphite composite material of which the racquet is comprised. This compares to the standard industry technique of air injection. The racquet is thus not hollow like conventional graphite racquets, and the walls therefore can be made thinner than those of existing graphite racquets still being of the same strength or being stronger, which gives the racquet exceptional performance. In addition, the overall dimensions of, for example the cross-section, of the racquet can also be reduced while still maintaining performance characteristics.

Description

technical field [0001] The present invention relates to apparatus and methods for graphite resin composite components, such as sports racket frames, golf club shafts and bicycle frames. [0002] Cross-References to Related Applications [0003] This application requires the priority of the Chinese patent filed in the People's Republic of China on June 18, 2009, application number 200910040320.9 and the priority of the U.S. provisional patent filed on December 9, 2009, application number 61-285,051. This document includes The disclosures therein are included for reference. [0004] Statement of Federal Sponsorship of Research or Development [0005] (Not applicable) Background technique [0006] For many years, graphite composite sports racquet frames were produced by artificial jet molding. A typical process is to manually roll multiple layers of sheets or laminates (appearing as strips of planar material) to make "joints" to form a capsule, usually composed of fibrous m...
