あ。[Detailed Description of the Invention] This invention relates to fiber-reinforced plastics (hereinafter referred to as
Regarding the structure of a wood club head for golf with an outer shell made of FRP (abbreviated as FRP), the quality has been improved by devising the laminated structure of reinforcing fibers of the FRP outer shell that makes up the head body. So.

た。 However, in such conventional products, there is only one type of reinforcing fiber, which serves both to reinforce the outer shell structure and to smooth its surface, resulting in a lack of surface smoothness and poor appearance. Since the reinforcing fibers have a short length of about 10 mm, their reinforcing effect on the outer shell structure is insufficient, and the ball hitting efficiency is poor because the ball hitting energy or ball impact is not sufficiently transmitted between the ball hitting surface of the head and the shaft. In addition, because the outer shell structure and the core are mixed with fine ball hitting powder of about 10 .mu.m of glass or ceramic, there are various disadvantages such as an excessive increase in the weight of the bed body.

きる。 That is, to exemplify the manufacture of the above-mentioned wood club head, as shown in FIG. A pair of divided bodies 11 made of a first FRP molding material using two to three layers of sateen cloth as reinforcing fibers constituting the thin outer shell of the head (sole surface may not be used). , 12 are separately thermoformed under as high temperature and pressure as possible, and 5 to 15 reinforcing fibers made of twisted yarn cloth or roving cloth are further added to the portion 12a of the front split body 12 corresponding to the face portion of the head body. Stack and form into a thick layer. On the other hand, as shown in FIG. 4, an inner shell in which reinforcing fibers are impregnated with prepreg or liquid powder-cured synthetic resin is placed around a core material 13 made of foamed synthetic resin that has been previously formed into a desired head core shape. The inner molding material 15 is formed by winding and covering the second FRP molding material 14 constituting the inner molding material 15. At this time, the reinforcing fibers of the second FRP molding material 14 constituting the inner shell are arranged as shown in FIG.
Bag woven cloth 14 made of 5 to 15 layers of carbon fiber, glass fiber, Kevlar, etc.
a is the part 13 corresponding to the neck part of the head body of the core material 13
Almost the entire circumference of the part 13a corresponding to the spherical body part of the head body except b is covered, and the part 13b corresponding to the neck part of the core material 13 is covered with a different type of bag weave cloth 14b, and both bag weave cloths 14a are covered. , 14b so that their end edges partially overlap, it is preferable to tighten them while pulling them so that they come into close contact with the circumferential surface of the core material 13, in order to equalize the fiber density in the neck part and the ball-striking body part. It is. Next, as shown in FIG. 6, the internal molding material 15 is molded into the pair of divided bodies 11, 1 using an appropriate mold 16.
A wood club head as shown in FIGS. 1 and 2 can be obtained by inserting and fitting into the hollow interior formed by 2 and heat-pressing the two to integrate them.

Sateen cloth made of carbon fiber or a combination of carbon fiber and glass fiber is used as a reinforcing fiber body for FRP molding materials, and the overall thickness is
It is arranged so that the thickness is 0.5 to 1.0 mm to improve surface smoothness and shape followability, and the thickness of the part corresponding to the face part is arranged to be 3 to 8 mm, and the center of gravity is moved downward. Therefore, the thick portion is distributed such that it becomes thicker from the top to the bottom (T 1 ≦T 2 ). On the other hand, the FRP inner shell wrapped around the core material is arranged so that the fiber content of the bag weave cloth is 96 bundles x 6000 fibers/bundle and the thickness is 3 to 10 mm, preferably 4 to 7 mm. In addition, the amount of fibers in the portion corresponding to the neck portion is set to 32×3000 fibers/bundle, and is laminated relatively thickly. In addition, when arranging the sole weight member or the back weight member at an appropriate position of the head body, the first FRP molding material or the By incorporating and embedding it in the FRP molding material in step 2, it is possible to integrate it simultaneously with the molding of the head. Furthermore, the appearance can be improved by forming a fiber-free colored synthetic resin layer on the outside of the FRP outer shell, that is, on the outer surface.

ど、実用性にすぐれた効果を奏するものである。 As explained above, when molding the head outer shell and the inner head shell formed around the core material, the type, composition, and amount of reinforcing fibers in each part are varied, and the whole is heated under heat. Because it is made of a solid material, a high-quality FRP with a smooth surface can be obtained, and the thickened head face of the outer shell absorbs the impact when the ball is hit, and transmits the elastic waves to the entire outer shell. This makes it possible to improve the feeling, and by maintaining the thickness of the inner shell, the rigidity of the shell can be connected to the club shaft. In addition, since the core is made of foamed synthetic resin, the elastic waves of the impact when the ball is hit can be reflected and scattered on the surface of the internal bubbles, causing them to interfere with each other, which can be expected to alleviate the impact. It has excellent effects.
