An aerodynamic golf club head having crown attributes that impart beneficial aerodynamic properties.

A hollow golf club head includes a metallic front body coupled with a composite rear body. The front body includes a strike face and a surrounding frame that extends rearward from a perimeter of the strikeface. The rear body includes a crown member coupled with a sole member. The sole member has a structural layer formed from a filled thermoplastic material, while the resilient layer is bonded to the external surface of the structural layer and is formed from a fiber-reinforced thermoplastic composite material. The resilient layer has an opening through which a metallic weight pad at least partially extends. The weight pad is bonded to the structural layer and includes an aperture for attaching a metallic weight.

Embodiments of golf club heads with turbulators and methods to manufacture golf club heads with turbulators are generally described herein. Other embodiments may be described and claimed.

A golf club head comprising two components, wherein the first component comprise a ball striking surface, a striking face return, and a sole extension with a rear mass. And wherein the second component comprises a lower density material, comprising part of the crown and part of the sole. The first component comprises a majority of the mass of the golf club head, having a rear mass comprising 20% to 35% of the mass of the golf club head.

Described herein are embodiments of golf club heads having a balance of the following parameters: a low and back club head center of gravity position, a high moment of inertia, and low aerodynamic drag. Methods of manufacturing the embodiments of golf club heads having a balance of club head center of gravity position, moment of inertia, and aerodynamic drag are also described herein.

A golf club head including a face defining a loft plane, a rear, and a crown, the crown having a turbulator comprising a plurality of ridges. Each ridge includes a front surface nearest the face, a rear surface nearest the rear, and an apex at a maximum height relative to the crown surface. The front surface of each ridge includes a concave curvature relative to the loft plane and a convex curvature relative to the loft plane. The ridge apex is positioned closer to the rear surface of the ridge than the front surface of the ridge.

This invention provides a golf club with a club-head configured so as to decrease air resistance of the head by avoiding the air flows from retouching on the head surface. The club-head is provided with a ridge structure which contains a first ridge and a second ridge arranged at intervals in a downward direction of the air flows on at least the sole part of the head, wherein each of the ridges has the height of 0.2 mm to 3 mm and the breadth of 1 mm to 5 mm, the ridge structure being configured by plural ridges so as to displace the inclined angle of the ridges in a clockwise direction, resulting in generation of air vortex or whirls between the head surface and the surrounding air flows.

A golf club head includes a crown surface having an apex at a highest point and extending between the face, the rear, the heel and the toe of the golf club head. The golf club head also includes a plurality of crown turbulators projecting from the surface of the crown and located at least partially between the leading edge and the apex, wherein the height of each turbulator decreases from the leading edge toward the rear portion.

A method of making a golf club head includes the steps of providing a face of a club head, the face having a ball striking surface and a perimeter defining a border of the ball striking surface, providing a golf club head body that includes a crown, a sole, a toe, and a heel, attaching the face to a front portion of the club head body, and milling the ball striking surface and an edge portion of the face to cut a machined surface into the ball striking surface and the edge portion. The milled surface includes a plurality of first grooves located along the ball striking surface and defining a first depth, and a plurality of second grooves located adjacent the perimeter along the edge portion and defining a second depth. The first depth is different than the second depth.

A golf club head includes a crown surface having an apex at a highest point and extending between the face, the rear, the heel and the toe of the golf club head. The golf club head also includes a plurality of crown turbulators projecting from the surface of the crown and located between the face and the apex, wherein each adjacent pair of crown turbulators is separate and spaced apart to define a space between the adjacent pair of crown turbulators.
