本発明は、超軽量の金属製眼鏡フレームを形成する目的
に存効なＦＲＭ線材に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an FRM wire material useful for forming ultra-light metal eyeglass frames.
眼鏡フレームを構成する金属材料としては、黄銅（Ｃｕ
−Ｚｎ）、洋白（Ｃｕ−Ｎｉ−Ｚｎ）、燐青銅（Ｃｕ−
３ｎ−Ｐ）、モネル（Ｎｉ−Ｃｕ）、ニッケルークロム
−銀合金（Ｎｉ−Ｃｒ−Ａｇ）などが汎用されているが
、これらはいずれら８以上の高比重を有していることか
ら、昨今のフレーム軽量化の要求には応えることができ
ない。Brass (Cu
-Zn), nickel silver (Cu-Ni-Zn), phosphor bronze (Cu-
3n-P), monel (Ni-Cu), nickel-chromium-silver alloy (Ni-Cr-Ag), etc., are commonly used, but since they all have a high specific gravity of 8 or more, It cannot meet the recent demands for lighter frames.
近時、軽量化要求に沿うものとしてＴｉ系のフレームが

していない。Recently, Ti-based frames have been attracting attention as they meet the demand for weight reduction. However, when viewed from the material density, T
Al-based metals, which have a significantly lower specific gravity than i, are more suitable for the purpose of weight reduction, but this material is not widely used except for practical examples of AQ alloy frames in some sunglasses.
この理由は、材質的に強靭性と弾性率に乏しい点゛に主
因がある。眼鏡フレームは、レンズを強固に支持すると
共に外的な衝撃、変形力などに対し十分に耐える強度な

しない。そのうえ、軽量化の指向はフレームの細身傾向
を一層強めており、この面の強靭度保持性からもＡｌ基
金属はフレーム材料としての宵月性が少ないとされてい
る。The main reason for this is that the material is poor in toughness and elastic modulus. Eyeglass frames must firmly support the lenses and must have sufficient strength and resilience to withstand external impacts, deformation forces, and the like. However, pure A17 and Al-based metals including alloys inherently do not satisfy the above strength characteristics. Furthermore, the trend toward weight reduction has further strengthened the tendency for frames to be slender, and Al-based metals are said to be less durable as frame materials due to their ability to maintain toughness in this respect.

のである。The present invention greatly improves the strength of the material by subjecting Al-based metal to FRM treatment, thereby successfully developing a wire rod for forming ultra-light frames, which was conventionally considered impossible to produce.

を備えるものである。The SiC whiskers used as reinforcing materials are SiC acicular single crystals with a density of 3.19 and a diameter of 0.1, obtained by reacting 5iOz-containing powder with a carbonaceous material such as carbon black at high temperature.
It has fine fiber properties of ~10 μm and an aspect ratio of 50 to 300.

In addition, alloys consisting of AQ and II or 2M or more such as Mg1Cu, Si, etc. are used, and the FRM wire is obtained by the composite method as exemplified below.SiC whiskers are mixed with water or an organic solvent containing an appropriate binder component. After dispersion, the mixture is filtered under normal pressure or increased pressure, and the remaining wet whisker cake is dried as it is or compressed to a predetermined density to form a cylindrical preform. This S

The FRM billet is prepared by impregnation and coagulation while being held under a pressure of Kg/cm'. In this case, the compound S
Although the volume fraction (Vr value) of iC whiskers depends on the density of the preform, it is usually easy to form a composite with Vfl in the range of 0 to 30%. Next, the FRM billet is made into a wire rod by subjecting it to hot working, cold working, and the like.

軽減することが可能となる。The FRM wire of the present invention is repeatedly drawn to form a wire and then formed into eyeglass frame parts using a known processing method.The strength characteristics of the wire are significantly improved through the composite action of SiC whiskers. Because of this, it maintains sufficient toughness and resilience even through fine wire processing. Furthermore, since the matrix is made of an AQ-based metal with a low specific gravity, combined with the effect of thinning the wires, it is possible to significantly reduce the weight of the entire frame.
