【発明の詳細な説明】
本発明は繊維複合金属材料の製造法に係り、更
に詳しくは繊維間への金属溶湯の侵入の容易化を
図り繊維と金属との密着性を改善した繊維複合金
属材料の製造法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a fiber composite metal material, and more specifically to a fiber composite metal material that facilitates the penetration of molten metal between fibers and improves the adhesion between fibers and metal. This relates to a manufacturing method.
近年、各種構造部品の強度向上、耐熱性改善の
ため繊維複合金属材料の実用化が検討されてい
る。特に、軽量化が要求される自動車部品におい
て実用化の要請は大きい。 In recent years, the practical application of fiber composite metal materials has been studied to improve the strength and heat resistance of various structural parts. In particular, there is a strong demand for practical use in automobile parts that require weight reduction.
従来、係る繊維複合金属材料の製造法として繊
維集合体を金型の所定個所に設置し、該金型内に
高圧で金属溶湯を注湯するという方法が提案され
ている。この方法によれば、かなり高品質な繊維
複合金属材料が得られるはずであるが、実際には
製品形状により繊維集合体が溶湯を加圧する加圧
プランジヤから遠い位置にある場合、又は繊維集
合体と加圧プランジヤの間に薄肉部がある場合に
は繊維集合体まで加圧力が十分伝達しないため繊
維間に溶湯が十分浸透せず複合化による効果が得
られないという問題があつた。 Conventionally, as a method for manufacturing such fiber composite metal materials, a method has been proposed in which a fiber aggregate is placed at a predetermined location in a mold, and molten metal is poured into the mold at high pressure. According to this method, a fiber composite metal material of fairly high quality should be obtained, but in reality, depending on the product shape, the fiber aggregate is located far from the pressure plunger that pressurizes the molten metal, or the fiber aggregate If there is a thin walled portion between the fiber assembly and the pressure plunger, there is a problem in that the pressure is not sufficiently transmitted to the fiber aggregate, and the molten metal does not sufficiently penetrate between the fibers, making it impossible to obtain the effect of compositing.
また、保有する製造装置の関係で型締め力に制
約があり、金属溶湯への加圧力を大きくできない
場合があり、この場合も上記したことと同様な問
題があつた。 In addition, there are restrictions on the mold clamping force due to the manufacturing equipment that they have, and there are cases where it is not possible to increase the pressure applied to the molten metal, and in this case, the same problem as described above occurs.
本発明はこれら従来技術の問題点を解決するた
めになされたもので、製品形状に拘束されること
なく従来と同程度又はそれ以下のプランジヤ加圧
力で繊維間に金属溶湯が十分浸透する繊維複合金
属材料の製造法を提供することを目的とする。 The present invention was made in order to solve these problems of the prior art, and is a fiber composite in which the molten metal can sufficiently penetrate between the fibers with a plunger pressure equal to or lower than that of the conventional product without being restricted by the product shape. The purpose is to provide a method for manufacturing metal materials.
係る目的は、本発明によれば、金型で郭定され
た製品キヤビテイの所定個所に繊維集合体を設置
し、該製品キヤビテイに高圧で金属溶湯を充填し
た後、金属溶湯が凝固しない時期に、前記繊維集
合体近傍を別の加圧手段により局部的に加圧する
ことにより達成される。 According to the present invention, the fiber aggregate is installed at a predetermined location of a product cavity defined by a mold, and after the product cavity is filled with molten metal under high pressure, the molten metal is not solidified. This is achieved by locally pressurizing the vicinity of the fiber aggregate using another pressurizing means.
本発明において、繊維としてはアルミナ繊維、
アルミナ−シリカ繊維、カーボン繊維、ボロン繊
維等種々のものが使用できる。どの繊維を用いる
かは金属溶湯との濡れ性、強化目的に応じ適宜選
択することができる。 In the present invention, the fibers include alumina fibers,
Various materials such as alumina-silica fiber, carbon fiber, and boron fiber can be used. Which fibers to use can be appropriately selected depending on the wettability with the molten metal and the purpose of reinforcement.
金属溶湯としても種々のものが使用できるが、
一般にはアルミニウム、マグネシウム及びこれら
の合金が主に用いられる。 Various molten metals can be used, but
Generally, aluminum, magnesium, and alloys thereof are mainly used.
繊維集合体周辺部の局部加圧は金属溶湯が凝固
しない比較的早い時期に行う必要があり、凝固し
てからでは加圧の効果はなく、また早過ぎても効
果は薄い。係る局部加圧の位置は、繊維集合体か
ら約50mm以内であることが望ましい。これ以上離
れたところでは局部加圧による繊維間への金属溶
湯浸透効果が薄い。 It is necessary to apply local pressure around the fiber aggregate at a relatively early stage before the molten metal has solidified; the application of pressure has no effect after solidification, and even if it is too early, the effect is weak. The position of such local pressure is preferably within about 50 mm from the fiber aggregate. If the distance is greater than this, the effect of localized pressure on the penetration of the molten metal between the fibers is weak.
局部加圧個所は製品形状、繊維集合体装填位置
等によりほぼ定まるが、ピストン、カムシヤフト
の如く製品構造として繊維集合体装填位置の近傍
に穴又は凹部を有するものは、該穴又は凹部の部
分を加圧することにより鋳抜きによる穴又は凹部
の形成と金属溶湯浸透効果を高める局部加圧の両
者を同時に行うことができる。 The local pressure point is almost determined by the product shape, fiber aggregate loading position, etc., but if the product structure has a hole or recess near the fiber aggregate loading position, such as a piston or camshaft, the area of the hole or recess is By applying pressure, it is possible to simultaneously form holes or recesses by casting and apply local pressure to enhance the effect of molten metal penetration.
また、製品が上記の如き穴又は凹部を有しない
場合は繊維集合体装填位置近傍に局部加圧用の湯
溜まり部を設けておき、加圧プランジヤによる加
圧後前記湯溜まり部を局部加圧することができ
る。この場合は、局部加圧力は加圧プランジヤに
よる加圧力により大きくする必要がある。 In addition, if the product does not have holes or recesses as described above, a pool for local pressurization should be provided near the fiber aggregate loading position, and the pool should be locally pressurized after pressure is applied by a pressure plunger. Can be done. In this case, the local pressing force needs to be increased by the pressing force of the pressurizing plunger.
なお、本発明における加圧鋳造法としては、ダ
イカスト法、溶湯鍛造法等が適用できる。 Note that as the pressure casting method in the present invention, a die casting method, a molten metal forging method, etc. can be applied.
本発明によれば、製品形状等に起因して加圧プ
ランジヤによる加圧力だけでは十分な加圧力が伝
達できない個所においても局部加圧により必要な
加圧力を付与させることができるため、金属溶湯
が繊維間に十分浸透し、繊維と金属との密着力が
まし、そのため目的とする特性を備えた高品質の
繊維複合金属材料を得ることができる。 According to the present invention, the necessary pressure can be applied by local pressure even in places where sufficient pressure cannot be transmitted only by the pressure plunger due to the shape of the product, etc., so that the molten metal can be It sufficiently penetrates between the fibers and improves the adhesion between the fibers and the metal, making it possible to obtain a high-quality fiber composite metal material with the desired properties.
また、局部加圧を併用するため従来のように加
圧プランジヤにより高圧を印加する必要はなく加
圧鋳造装置の小型化を図ることができる。 Further, since local pressure is used in combination, there is no need to apply high pressure using a pressure plunger as in the conventional method, and the pressure casting apparatus can be downsized.
更には、従来ひけ巣を生じ易かつた肉厚部にも
金属溶湯が補強されるためひけ巣の発生をなくす
ことができる。 Furthermore, since the molten metal is reinforced even in the thick wall portion where shrinkage cavities are likely to occur in the past, the occurrence of shrinkage cavities can be eliminated.

により製品を取り出した。 First, the fiber aggregate 8 is placed in the lower mold 2 with the mold opened. Next, the product cavity 3 is defined by lowering the upper mold 1 and clamping the mold. At this time, the pressure pin 7 is at the position indicated by the solid line. In this state, pour the molten aluminum alloy 5 from the pouring port (not shown) and use the pressurizing plunger 6 to reach approximately 500 mm as shown by the arrow Pe.
The product cavity 3 was filled with the molten metal under pressure of Kg/cm 2 . While maintaining the pressure applied by the pressure plunger 6, after about 5 seconds, at a relatively early stage when the molten metal has not yet solidified, use the pressure pin 7 to move the molten metal to about 500 mm as indicated by the arrow Pd.
Pressure was applied to the position indicated by the broken line in Figure 1 at Kg/cm 2 . After solidifying the molten aluminum, the mold was opened and the product was taken out using an extrusion pin (not shown).

Because it is necessary to slide to the broken line position 11 against the pressure of , it is necessary to make the pressurizing force of the pressurizing pin 7 larger than the pressurizing force of the pressurizing plunger 6. In the case of the second embodiment, the pressurizing force of the pressurizing plunger 6 is 500 kg/
