摘要： Disclosed herein is an iron-type golf club head that comprises a strike plate, an enclosed internal cavity, and a rear aperture formed in a rear wall. The iron-type golf club head also comprises a stiffening plug, within the internal cavity and compressed between the back surface of the strike plate and the rear wall. The stiffening plug is insertable, through a rear aperture, into the internal cavity. The iron-type golf club head further comprises a rear fascia covering the rear aperture and at least a portion of the rear wall. A characteristic time (CT) at a geometric center of the strike face is at least 250 microseconds. A maximum thickness of the strike plate, at the strike face, is less than 3.5 millimeters, inclusive. The strike plate, excluding grooves, has a minimum thickness between 1.1 millimeters and 2.2 millimeters.

摘要： A method of creating a multi-layer composite strike face of a golf club head includes positioning a first non-cluster panel. The method also includes creating and attaching a cluster panel to the first non-cluster panel, which includes attaching a first elongated strip to the first non-cluster panel at a first strip angle, attaching a second elongated strip to a portion of the first elongated strip and a portion of the first non-cluster panel at a second strip angle, and attaching a third elongated strip to a portion of the second elongated strip, and a portion of the first non-cluster panel at a third strip angle.

摘要： A golf club head that comprises a hollow interior cavity, a first piece, a second piece, adhesively bonded to the first piece along a first bonded joint, a third piece, adhesively bonded to the first piece along a second bonded joint, and a fourth piece, adhesively bonded to the first piece along a third bonded joint. A volume of the golf club head is at least 120 cubic centimeters (cc) and at most 600 cc. The first bonded joint has a first-joint bond area. The second bonded joint has a second-joint bond area. The third bonded joint has a third-joint bond area. A summation of the first-joint bond area, the second-joint bond area, and the third-joint bond area is at least 1,950 mm2 and at most 3,400 mm2.

摘要： Disclosed herein is a golf club head that comprises a strike face. The strike face has a central region, defined by a forty millimeter by twenty millimeter rectangular area centered on a center of the strike face and elongated in a heel-to-toe direction. Within the central region, the strike face has a characteristic time (CT) of no more than 257 microseconds. Within the central region, no less than 25% of the strike face has a coefficient of restitution (COR) of at least 0.8. Within the central region, no less than 60% of the strike face has a CT of at least 235 microseconds. Within the central region, no less than 35% of the strike face has a CT of at least 240 microseconds.

摘要： A method of making a golf club head includes interposing bonding tape between a first piece and a second piece of the golf club head such that the first piece is temporarily adhered to the second piece via a tackiness of the bonding tape. The method additionally includes positioning the first piece, the second piece, and the bonding tape, interposed between the first piece and the second piece, in a vacuum bag, and reducing a pressure within the vacuum bag, relative to a pressure external to the vacuum bag, such that the vacuum bag collapses onto the first piece and the second piece and compresses the bonding tape between the first piece and the second piece. The method also includes heating the bonding tape, at least to a curing temperature of the bonding tape, when the pressure within the vacuum bag is reduced.

摘要： A method of removing a backing layer from a panel, made of an uncured pre-impregnated fiber-reinforced polymer, comprises a step of orienting the panel into a backing-separation orientation relative to an edge-engagement tool. The method also comprises a step of positioning the panel into a backing-separation position relative to the edge-engagement tool. The method further comprises a step of moving the edge-engagement tool, when the panel is in the backing-separation orientation and the backing-separation position, so that backing-engagement features of the edge-engagement tool engage the backing layer, at only an edge portion of the backing layer, and just the edge portion of the backing layer separates from the panel. The method additionally comprises a step of gripping the edge portion of the backing layer, and, when gripped, moving the backing layer relative to the panel so that an entirety of the backing layer separates from the panel.

摘要： A golf ball having a North pole and a South pole, an equator and a primary meridian, the equator and primary meridian divide the ball into North, South, East and West hemispheres, and Northeast, Northwest, Southeast and Southwest quadrants. A grid pattern projected on the ball surface divides the ball laterally and longitudinally into a number of overlapping zones. The dimples within the zones have average depths hex, hsx, hpx, hei, hsi and hpi and selected values of Δe, Δs and Δp which are the difference between the minimum and maximum values of the relative ratios of the dimple depths, hexr/heir, hsxr/hsir and hpxr/hpir determined when the ball is rotated by a value of θ from 0 to 360° about its polar axis.
