Regarding the manufacturing method of the head of a wood golf club with an outer shell made of FRP (abbreviated as FRP), long fibers knitted into a bag weave sleeve are used as the reinforcing fibers of the FRP outer shell that forms the head body, and as the fiber reinforcing means. By making improvements, moldability and quality are improved.

が悪いなど、種々の欠点があつた。 However, as is well known, with such conventional heads, there are various difficulties in manufacturing them due to the complexity of the unique shape of the outer periphery of the head, and the FRP outer shell that forms the head body is difficult to manufacture. Since short glass fibers are used as reinforcing fibers, the fiber arrangement itself is random and has insufficient elastic modulus.
For this reason, not only is the repulsion force at the time of hitting a ball inferior, but the reinforcing effect of the fibers is also insufficient, and the thickness of the outer shell layer must necessarily be increased, resulting in an increase in weight. Furthermore, in such a reinforced structure of the FRP outer shell, the fiber arrangement in the main body part of the head and the head neck part to which the club shaft is fixed is the same, the same type, and the same amount. It is difficult to distribute the fibers, and the amount of fiber used in the main body part is limited by the amount of fiber in the neck part.In addition, when reinforcing fibers are made of pine or flat woven fabric, there are It had various drawbacks, such as not adapting to complex curved shapes and poor followability in equalizing fiber arrangement.

うなクラブヘツドを得るものである。 That is, in order to manufacture the above-mentioned wood club head, as shown in FIGS. A core mold 11, which serves as a core and is separately shaped in the shape of the core of the head body, is placed at the tip of a rod-shaped jig 10, which also serves as a jig (in this case, a protector 9 is inserted and fixed to the club shaft in advance). A fibrous body is supported and fixed in such a manner that the portion 10a partially protrudes toward the sole surface side, and is separately formed on the main body portion 11a of the head body of the core mold 11 and the corresponding portion of the neck portion 11b. 12 and 13 (see Figure 3).
The reinforcing fiber bodies 12 and 13 are made of a hollow weave sleeve made of diagonally knitted carbon fibers, glass fibers, Kevlar, etc., and the diameter (number of fibers/
bundle), number, elastic modulus and strength of the main fibers,
Alternatively, the mixing ratio of high elastic fibers and other types of fibers can be made thicker, larger, higher (3000 Kg/mm 2 or more) and lower (180 Kg/mm 2 or less) than the head neck reinforcing fiber body 13, or have high elasticity. Both reinforcing fiber bodies 12, 1 are set so that the ratio of fibers is large.
3 over the head main body part 11a and head neck part 11b of the core mold 11 and squeezed while pulling, and both ends 12a and 13a of them were
In particular, the main body portion 11a of the head and the neck portion 11 are subjected to the maximum stress such as torsion, shearing force, tensile force, compressive force, etc.
core mold 1 by overlapping each other near the boundary a with b
It is made to closely adhere to the outer peripheral surface of No. 1 with good followability. The reinforcing fiber bodies 12 and 13 are impregnated with an uncured liquid synthetic resin such as epoxy resin or polyester resin, and are then applied to form the outer shape of the head of a mold 16 consisting of a pair of left and right split molds 14 and 15. (See FIGS. 4 and 5). At this time, when positioning the core mold 11 in the cavity 17 of the mold 16, the split mold 1
This is done by holding the tip 10a of the rod-shaped jig 10 and the protector mounting base between the rod-shaped jig 10 and the protector mounting base. Then, after performing a hot-press molding process and releasing the mold, as shown in FIG.
A club head as shown in FIGS. 1 and 2 is obtained by cutting and removing 0a and sealing the cut opening.

る。 By the way, the density of the reinforcing fibers knitted into a sleeve used in this invention varies from a minimum of 48 strokes with 3000 strands or 6000 strands of yarn in one direction, since the type of sleeve is changed between the hosel part and the ball striking part of the head body. Maximum 96 strokes or thickness 0.3
It is made by polymerizing a minimum of 6 pieces to a maximum of 50 pieces per mm, and the type of reinforcing fiber is knitted so that the carbon fiber sleeve accounts for 30% or more, and other types include Kevlar, glass fiber, Alternatively, a sleeve made of a combination of carbon fiber and glass fiber is used. Furthermore, it is also possible to use other cloth such as glass fiber or Kevlar for the ball hitting part (face surface) of the head body, and in this case, the thickness used ranges from two layers of cloth with a minimum thickness of 0.3 mm to a maximum The range is 30 layers. Further, it is also possible to use a continuous hollow weave sleeve extending from the main body portion of the head to the net portion as the reinforcing fibers of the outermost layer and the innermost layer.

るものである。 As explained above, in forming the head main body with an FRP outer shell, the reinforcing fibers of the FRP molding material are knitted into hollow weave sleeves for the main body part of the head and the head neck part to form a core material. Since the reinforcing fibers are closely wrapped around the head components, the reinforcing fibers can be placed on the head components with good followability.Furthermore, since they are long fibers, the direction of fiber arrangement is equalized, and the reinforcing effect is tailored to the characteristics of each part. This has excellent practical effects, such as being able to further increase the elastic modulus and repulsion force when hitting a ball.
