Description

[Detailed Description of the Invention] Current golf club heads include Purge Moji, Metal (
Stainless steel), carbon fiber reinforced resin (hereinafter abbreviated as "carbot"), etc. are used.

However, great care must be taken with these clubheads after Corfu in the rain, as they are affected by the 11111 degrees.

There is no effect of JE on metal and carbon at 41a degrees! , C metal is a long i9' which is said to have a suitable price from the club face when hitting the ball and a sense of stability in the ball's trajectory.
``'x--I do, but since the density of the metal itself is large'
In order to maintain the proper weight of the 7-rough heel, the C must also be made 71-ke smaller.For this reason, metal has the disadvantage that it lacks stability when hitting the ball, and the wall thickness must be made as thin as possible. This has the disadvantage that the face tends to become distorted.

The Noy-Bot is a golf club that has a lower density than metal, and can be used with a two-piece pole to achieve a long distance, but because the ball's N-toe properties are too good from the club face when hitting the ball, the face and ball The disadvantage is that the contact time is short and the ball lacks stability.

The above-mentioned problems have been pointed out by many golfers, and it would be great to see a golf club that combines the advantages of metal and carbon.

It is clear from the present invention that the needs of many golfers can be met by using inorganic m'#f for the Corfu club head made of light metal material. became.

Examples of inorganic fibers include alumina fibers, carbon fibers, boron fibers, silicon carbide fibers, and silica fibers. When it comes to aluminum clearing (C)

Since fiber deterioration is difficult to occur, fibers for reinforcing lightweight metal materials are preferably used in the present invention.

There are two types of alumina fibers: wool-like short fibers and continuous long fibers.

- An inorganic fiber-reinforced metal material with high strength can be obtained.

Alumina and lt It/A jMR also have different properties depending on the manufacturing method, composition, crystal type, etc., and the strength of the reinforced lightweight metal GJ material may change, or an inorganic material with suitable strength and elastic modulus for a golf club head. The inorganic fiber most suitable for making fiber-reinforced lightweight metal materials and the fiber that can most clearly exhibit the effects of the present invention is Japanese Patent Publication No. 51-1876 El.
J) with the aluminum f-trade 1 fiber listed in J).

That is, the general formula (where Y is an organic residue, halogen, or one hydroxyl group)
This includes more than two types. ) A polyaluminoxane having a structural center point represented by C is an alumina fiber obtained by mixing two or more kinds of fibers, preventing the first compound, and firing the obtained precursor W@fiber, and preferably has a silica (Si02) content of 2% by weight. The above is an alumina fiber having a content of 25% by weight or more and showing substantially no reflection of σ-A120s in its X-ray structure. The alumina fibers may include lithium, beryllium, porphyry, sodium, maquo, sium, phosphorus, potassium, calcium, titanium, black bustard, yttrium, zirconium, lanthanum, tungsten, and barium within a range that does not impair the effects of the present invention. It may contain refractory compounds such as one or more oxides of .

Examples of 1% fit M group materials and 17 include aluminum, aluminum alloys, magnesium, and magnesium alloys.

Table 1 shows the physical properties of the Colts club head material. From these values, it can be seen that the lightweight metal material reinforced with inorganic fibers has properties similar to carbon, even though it is a metal.
A golf club using a lightweight metal material strengthened by this inorganic fiber can be a golf club that combines the advantages of both metal and carphone golf clubs.

Tests have shown that golf clubs made using the lightweight metal material toughened by the inorganic fibers of the present invention for golf club heads are resistant to humidity, are easy to care for, are soft, and have a low density. Since metal is smaller and closer to a carphone, the thickness of the club head can be designed to an appropriate size, and the sense of stability when hitting the ball is increased compared to metal.

In addition, although it is difficult to judge the ball release property from the club face when hitting the ball from the physical property values, test results show that the ball release property of the golf club using the lightweight metal material toughened by the inorganic fibers of the present invention is It's like metal, and I found that the ball's stability is good.

Furthermore, as can be seen from the physical property values in Table 1, the Colts club head material of the present invention is a material that is extremely scratch resistant.
It is found that it is suitable as a golf club head material.

It was also found that the ball flight distance was greater than that of conventional metals, and was equivalent to carbon, which is said to have good flight distance.

Taking all of this into account, the Corfu club head made of lightweight metal material strengthened by non-mIJf4 fibers of the present invention solves the problems of conventional golf clubs and is a good Corfu club head that is easy to use for golfers. It turns out that.
