A manufacturing method of carbon fiber rackets includes the steps of preparing a core material and setting a blowing bag on the core material, wrapping multiple prepreg layers of carbon fiber materials on the outside of the blowing bag to become a sample to be molded, taking out the core material and placing the sample to be molded into a mold, closing the mold and heating and pressurizing the mold, and inflating the blowing bag to harden the multiple prepreg layers, expelling the air in the blowing bag to reduce the volume of the blowing bag, and opening the mold and drawing out the blowing bag and then taking out the hardened racket frame rough embryo thus obtained.

Aspects of the present disclosure include a pickleball paddle that is formed using a plastic or composite molded material. A composite material is wrapped around a center and placed in a mold to form a paddle frame or arranged around a paddle frame. In some embodiments, additional composite material is wrapped at specific positions to tune the balance point and rebound characteristics of the finished paddle The mold is heated to cure the composite material within the mold cavity. Face shells are then added to complete the paddle.

The present invention relates to a ball game racket frame with a head portion and a handle portion, wherein the ball game racket frame comprises a fiber composite with at least one multi-fiber roving that is at least partially twisted.

A lacrosse head pocket and a related method of manufacture are provided to facilitate consistent, repeatable and/or custom manufacture of lacrosse equipment. The pocket can be constructed from multiple different sections joined with one another, or can be knitted, weaved or otherwise assembled on an automated assembly machine from strands, and/or can be formed as a unitary textile material having regions/sections with different physical and/or mechanical properties. The pocket can be integrally molded within portions of a lacrosse head to eliminate manually constructed connections between the pocket and lacrosse head. The lacrosse head can be integrally molded with a lacrosse handle to provide a one-piece unitary lacrosse stick. The lacrosse pocket body can include one or more fused pocket areas. Related methods of manufacturing also are provided.

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. Advantageously, inner and outer tubular members may be used to form the racquet frame, with the inner tubular member extending around the head of the racquet frame. 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.

The present disclosure provides single-piece objects and methods for forming such objects. Such single-piece objects may be bicycle frames.

A lacrosse head pocket and a related method of manufacture are provided to facilitate consistent, repeatable and/or custom manufacture of lacrosse equipment. The pocket can be knitted, weaved or otherwise assembled on an automated assembly machine from strands, and/or can be formed as a unitary textile material having regions/sections with different physical and/or mechanical properties. The pocket can be integrally molded within portions of a lacrosse head to eliminate manually constructed connections between the pocket and lacrosse head. The pocket can include a perimeter flange constructed from special materials and/or a perimeter flange including intermittent voids along an outer edge so that the perimeter flange stretches when the pocket is in a loaded state with the lacrosse ball therein, thereby providing dampening to the pocket when a lacrosse ball exerts force upon the pocket in the loaded state.
