Abstract: A carbon-fiber composite golf club head comprises a carbon-fiber composite body, at least one carbon-fiber composite component and at least one weight component. The carbon-fiber composite body comprises a hollow body portion, one-piece formed by stacking carbon fiber prepreg materials, and a striking face portion disposed at a front end of the body portion. The at least one carbon-fiber composite component is mounted to at least one opening of one or both of a crown and a sole of the body portion. The at least one weight component is mounted at a rear end of the carbon-fiber composite body. By combining the carbon-fiber composite body, one-piece formed by carbon fiber composite material and comprising the body portion and the striking face portion, with the at least one carbon-fiber composite component, a weight of a main part of a club head is significantly reduced to increase a weight of counterweight.

Abstract: A composite golf club head and a method for manufacturing the same are provided. The composite golf club head has a carbon fiber composite body and a striking face. The carbon fiber composite body is formed by multiple carbon fiber prepreg materials or multiple composite prepreg materials including carbon fiber with stacking, a positive pressure, a vacuum negative pressure, and heating. The striking face is made of a carbon fiber composite or metal material, and is fixedly glued to a front opening portion of the carbon fiber composite body. A weight of the carbon fiber composite body is reduced. Center of gravity and moment of inertia can be adjusted easily according to striking distances or feel of striking of different golf club heads for enhancing a striking performance of the composite golf club head.

Abstract: A composite golf club head has a head body and a striking plate. The head body has a main portion and a hosel. The main portion is made of carbon fiber composite material and is integrally formed as a single part. The hosel is formed on a front end of the main portion. The striking plate is mounted on the head body. A method of manufacture the composite golf club head comprises steps of putting a plurality of carbon fiber composite prepregs that are piled up and the striking plate into a mold assembly, closing the mold assembly to form a blank of a golf club head, using a pressure forming device to create vacuum inside the mold assembly and to heat the mold assembly to get a semi-finished if golf club head, and deburring to form the composite golf club head.

Abstract: A golf club head includes a front face having a grooved striking zone for impacting a golf ball, a rear face opposite to said front face, a top portion, a sole portion, a toe portion, a heel portion, a hosel portion having a shaft-receiving bore. The toe portion surface meets the front face along a first edge, and the toe portion extends outwardly from the first edge in a direction away from the hosel portion such that the vertical projection of the toe portion onto a plane containing the front face is substantially located outside of the front face. Besides, the sole surface meets the rear face along a trailing edge and meets the toe portion surface along a second edge, and the angle included between the trailing edge and the second edge is less than 90 degrees.
