積層させたプリプレグが用いられるのが一般的である。Conventionally, a golf club head 1 mainly composed of a fiber reinforced plastic formed by impregnating a resin into carbon fiber, glass fiber, aromatic polyamide fiber or the like is shown in FIGS.
As shown in FIG. 10, except for the sole portion 2, it is covered with a fiber-reinforced plastic 3 and molded, and most of the form of the material is a sheet mold compound (SM).
C), a cross prepreg or a unidirectional prepreg is used, and in particular, the face portion 4 of the club red 1 generally uses a prepreg in which fibers are laminated.

クラブ使用時に多発し易いと言う問題があった。Further, during molding of the club head, the cross eyes are likely to be disturbed, which has led to not only a problem in appearance but also a decrease in strength of the face portion 4. Recently, a club head in which only the face insert is reinforced by using a three-dimensional fabric has been proposed (for example,
59-133264, JP-A-61-58676, JP-A-62
There is a problem that chipping at the boundary of the face surface tends to occur frequently when the club is used.
