A golf club with a multi-material face is disclosed herein. More specifically, the golf club head in accordance with the present invention has a multi-material striking face portion that is made out of a backing layer having a frontal pocket, made out of titanium, and an insert, made out of a composite material, adapted to be inserted into the frontal pocket. The frontal pocket and the insert could have complementary dovetail shaped undercut features to create a mechanical bond between these two components. The insert may be bonded to the frontal pocket using an adhesive impregnated within a glass fiber weave.

Embodiments of golf club heads and methods to manufacture golf club heads are generally described herein. In one example, a golf club head may include a body portion with an interior cavity and face portion, and weight portion and a wall portion on a bottom portion of the body portion extending into the interior cavity. A polymer material may be in the interior cavity located between and coupled to the wall portion and the weight portion. The wall portion may be farther from the face portion than to the weight portion. The weight portion may be closer to a front portion than to a rear portion of the body portion. A distance between the weight portion and the face portion may be greater than a distance between the weight portion and the wall portion. Other examples and embodiments may be described and claimed.

A racquet including a tubular frame formed of a fiber composite material, a pallet and a butt cap. The frame includes first and second end regions and a mid-region. The handle portion includes a distal region, proximal region and a central region positioned between the distal and proximal regions of the handle portion. The central and proximal regions of the handle portion have outer surfaces that define first and second transverse cross-sectional areas, respectively. The second transverse cross-sectional area is larger than the first transverse cross-sectional area. The pallet is coupled to and longitudinally extends over the central region but not over the proximal region of the handle portion. The butt cap is secured to the proximal region and includes a peripheral wall and less than half of the length of the peripheral wall extends over the pallet.

A high forgiveness wood-type golf club head comprises a body and a face. The body comprises a sole that forms a bottom portion of the golf club head, a crown that forms a top portion of the golf club head and a skirt that forms a periphery of the golf club head between the sole and the crown. The face place is positioned at a front portion of the golf club head opposite a rear portion of the golf club head. The body defines an outer periphery having a generally triangular shape in plan.

Some disclosed golf club heads include body having at least one raised sole portion and a cantilevered ledge extending down around a perimeter of the club head below the level of the raised sole portion. Some disclosed golf club heads include one or more sole openings in the body and a sole insert that is mounted inside the body over the sole openings. The sole can include weight tracks as well, and a rear weight track can extend between a toe side sole opening and a heel side sole opening. A crown insert can also be included that is mounted over an upper opening in the body.

A state of a golf club head placed such that a shaft axis line is vertical to a horizontal plane and a normal line is parallel to a first perpendicular plane on which the shaft axis line lies is defined as a 0-degree state. A direction parallel to the first perpendicular plane and parallel to the horizontal plane is defined as a projection direction. A projected area of the head projected in the projection direction when the head is rotated by θ°about the shaft axis line toward a back side from the 0-degree state is denoted by WAθ. WAθ is divided by the shaft axis line into a first region (having an area denoted by Afθ) and a second region (having an area denoted by Abθ), and a difference (Afθ-Abθ) is denoted by Sθ. S90 is -4500 (mm.sup.2) or less. S15 is 4700 (mm.sup.2) or less.

A shaft has a weight of 50 g or less. A forward flex is 110 mm or less. A backward flex is 100 mm or less. A shaft torque is 4.0° to 6.5°. The shaft includes a first hoop layer, a second hoop layer longer than the first hoop layer, and a third hoop layer longer than the second hoop layer. An outer diameter at a position 550 mm apart from a tip end is D5. An outer diameter at a position 950 mm apart from the tip end is D9. A crushing strength at the position 550 mm apart from the tip end is F5. A crushing strength at the position 950 mm apart from the tip end is F9. F5/D5 is 1.5 or greater and 2.5 or less. F9/D9 is 1.0 or greater and 2.0 or less. A difference (F5−F9) is 4 kgf or less.

Provided is a hollow shaft including a hoop layer. The shaft weight is 50 g or less. The shaft has a flexural rigidity EI (N.Math.m.sup.2) and a shaft wall thickness t (mm). In a first region having a distance of 200 mm to 300 mm from the tip end, EI/t is 10 or greater and 40 or less. In a second region having a distance of 800 mm to 900 mm from the tip end, EI/t is 45 or greater and 80 or less. The hoop layer includes a partial hoop layer disposed in a part of an entire length of the shaft. The partial hoop layer includes a specific butt hoop layer that is not present in the first region and that is disposed over an entirety of the second region. The specific butt hoop layer has a thickness of 0.05 mm or greater.

A shaft includes a tip end and a butt end. In the shaft, a flexural rigidity at a point located 130 mm apart from the tip end is denoted by E1, a flexural rigidity at a point located 1030 mm apart from the tip end is denoted by E10, and a torsional rigidity at the point located 130 mm apart from the tip end is denoted by G1. A ratio (E10/E1) is greater than or equal to 2.4 and less than or equal to 8. The flexural rigidity E1 is less than or equal to 2.5 (kgf.Math.m.sup.2). The flexural rigidity E10 is greater than or equal to 6.0 (kgf.Math.m.sup.2). The torsional rigidity G1 is greater than or equal to 0.5 (kgf.Math.m.sup.2). A ratio (E1/G1) is greater than or equal to 1.0 and less than or equal to 4.0.
