The Al alloy composition is not determined by fully considering the composite characteristics or composite effect with C fibers. Therefore, the mechanical properties of composite materials having these Al alloys as a matrix cannot be said to be sufficient in the as-forged state.

に至った。Conventional Al alloy composite materials have low mechanical properties in the as-molten forged state, and in order to obtain Al alloy composite materials with sufficient mechanical properties, aging is required in addition to heat treatment, that is, solution treatment. It was necessary to treat it. One of the reasons for the low mechanical property values at the stage of molten metal forging is that, as mentioned above, the Al alloy for the matrix in the Al alloy composite material has not been sufficiently studied for use in composite materials, and the existing This is thought to be due to the fact that it was simply selected appropriately from among Al alloys. Therefore, the present inventors have determined that in order to obtain an Al alloy composite material that exhibits sufficient mechanical properties even when heat treatment, which is a cause of increased production costs, is omitted, S
We have come to the conclusion that it is necessary to develop a new aluminum alloy for matrix that has an appropriate composition as an iC-based composite material.

組成を特定した理由は次の通りである。While carrying out various experiments to realize this idea, the present inventors discovered that an Al-Cu alloy containing an appropriate amount of Cu or an appropriate amount of M
They discovered that if an Al-Mg alloy containing g is selected as the Al alloy for the above-mentioned composite material, a composite material that exhibits excellent mechanical properties even in the as-cast state can be obtained, and they have filed a patent application with Hikari. However, further research later revealed that Al-Cu-M containing appropriate amounts of Cu and Mg at the same time.
It was discovered that if g-alloy is used as a matrix, excellent mechanical properties superior to conventional products can be exhibited in the as-molten forged state, and the present invention has now been completed. That is, the present invention has the greatest feature in that an Al-Cu-Mg alloy with a specific composition is selected as a matrix component used in combination with a reinforcing material made of SiC whiskers or SiC fibers. The reason for specifying the composition of the Al alloy is as follows.

ましい含有率は３〜５％の範囲である。Cu: 3-7% Cu is an indispensable component to guarantee the mechanical properties of composite materials at the stage of molten metal forging, and 3% or more is required to ensure initial strength even without heat treatment. must be included. However, when the amount of Cu exceeds 7%, a large amount of intermetallic compound consisting of Cu A 12 is produced in the matrix, resulting in a decrease in toughness. A more preferable content of Cu is in the range of 3 to 5%.
Ｍ ｇ ： ０．５ 〜３％

ある。Mg: 0.5 to 3% Mg is a component that provides good mechanical properties even after molten metal forging, and in particular has the effect of significantly increasing the strength of the composite material depending on the thermal history during forging. In order to effectively exhibit this effect, the content must be 0.5% or more, but if it exceeds 3%, the strength will actually decrease, so it must be kept below 3%. A more preferable Mg content is around 1%.

There is no fear that the two will have a negative effect on each other, but rather the effects of both are additive or additive, and a composite material that exhibits excellent mechanical properties even in the as-forged state can be obtained.

ある。The inevitable impurities contained in the above Al alloy include Si,
Examples include Fe, Mn, Zn, etc., but since these reduce the ductility of the matrix, it is desirable to keep the accountant content below 1%. In addition, in the present invention, Al-Cu-Mg
It is also possible to add about 0.2% or less of Ti or B to the alloy to refine the crystal grains and further improve the mechanical properties.

These demands can also be met by adding solution treatment and aging treatment.
