As the CF RAI, carbon fibers having a diameter of 7 to 8 μm and a long fiber shape were embedded in aluminum in the reinforcing direction (one direction). Note that instead of the long fiber shape, short fibers having an aspect ratio (fiber N length/fiber diameter) of 20 or more may be used.

場合がある。As can be seen from FIG. 2, in the conventional CFRAI, the tensile strength and coefficient of thermal expansion are uniquely determined by determining the carbon fiber content. For example, when the fiber content is 20%, the tensile strength is 65 kg/ml' and the thermal expansion coefficient is 8.3X10-6/'C. That is, if the tensile strength is 65 kQ/mmZ, the coefficient of thermal expansion is 8.3X10
-'/"C, and other directivity cannot be taken. However, depending on the use of FRM, it may be desirable to have a high coefficient of thermal expansion while keeping the tensile strength the same, or conversely, it is desirable to have a high coefficient of thermal expansion while maintaining the same tensile strength. There are cases where it is desired to increase the tensile strength.

供することを目的とする。The present invention was devised in view of the fact that the quality of conventionally manufactured CFR = "A1" is uniquely determined by determining the carbon fiber content as described above. The present invention aims to provide a CFRAI whose tensile strength and coefficient of thermal expansion can be set to desired values according to the use of the CFRAI without losing its advantages (high strength, light decoyability).

張率は２Ｘ１０−６／’Ｃ以上であることが望ましい。Examples of fibers C having a coefficient of thermal expansion larger than that of carbon fibers and a tensile strength of 200 kg/mm2 or more include silicon carbide (SiC) fibers and aluminum (Δ1203) fibers. The reason why the tensile strength is required to be 200 mm/mm2 or more is because if it is smaller than that, the high strength, which is one of the advantages of carbon fibers, will be diminished, and the strength of the FRM will be too low. . The coefficient of thermal expansion of these fibers is preferably 2X10-6/'C or more.

る。If it is smaller than 2X10-67''C, the difference in thermal expansion coefficient from that of carbon fiber will be too small, and there will be no advantage of using two types of m-fibers with different properties as a reinforcing material.

To be determined accordingly. For example, if you want to obtain an FRM with a large coefficient of thermal expansion, the proportion of carbon fibers should be relatively small.Also, the orientation of these fibers should be determined depending on the desired use of the FRM.
If it is desired to obtain RM, the fibers are oriented in one dimension, and if it is desired to obtain FRM reinforced in two dimensions, the fibers are arranged in two dimensions. Furthermore, if it is desired to obtain an FRM having properties that are isodirectional in three dimensions, the fibers are arranged equidirectionally and randomly in three dimensions.

A method such as a melt impregnation method or a melt-field forging method can be used. Diffusion bonding is a method in which metal foil or metal powder and fibers are slowly and slowly integrated using hot pressing. The melt impregnation method is a method in which the fibers are brought into contact with and penetrated by a molten base material, and the molten metal forging method is a method in which the contact and penetration are carried out under pressure.

炭素繊維の割合が減少するにつれ増加している。FIG. 3 is a graph showing the tensile strength and thermal expansion coefficient characteristics of the FRM manufactured in this example, with total fiber content as the horizontal axis. As can be seen from Figure 3, when the total fiber content is the same, the tensile strength depends on the amount of carbon in the fiber! The coefficient of thermal expansion decreases as the proportion of I fibers decreases, and conversely, the coefficient of thermal expansion increases as the proportion of carbon fibers decreases.

As shown in FIG. 4, by changing the mixing ratio of carbon fibers and silicon carbide fibers, FRMs with different coefficients of thermal expansion can be obtained even if the tensile strength is the same. That is, when two types of fibers, carbon fibers and silicon carbide Ql fibers, are used as reinforcing materials, an FRM having characteristics included in the shaded area shown in FIG. 4 can be manufactured.

。Second Embodiment The second embodiment is also substantially the same as the first embodiment. The difference between the second example and the first example is that silicon carbide is used as the reinforcing fiber!
&! Alumina fiber instead! The point is that fibers were used. The tensile strength of aluminum is 250 kc+/mm2, and the coefficient of thermal expansion is 8.8x101'/"μ from C1 diameter number.

第２実施例では同一の引張強度に対し、製造し待る熱膨
張率の幅が第１実施例の場合よりも大きくなっている。FIGS. 5 and 6 show the characteristics of the FRM according to the second embodiment. As can be seen from FIG. 5, when the proportion of carbon fiber in the reinforcing material decreases; the tensile strength decreases, as in the case of Example n1, and conversely, the coefficient of thermal expansion increases. However, the degree of increase in the coefficient of thermal expansion is greater than in the first embodiment. This is because the Lumino fiber has a larger coefficient of thermal expansion than the silicon carbide fiber. Furthermore, as can be seen from FIG. 6, in the second embodiment, for the same tensile strength, the range of thermal expansion coefficients after manufacturing is larger than in the first embodiment.
即ち第２実施例にがかるＦＲＭの特性は、第６図の斜線

第４図の斜線部の面積よりも広くなっている。That is, the characteristics of the FRM according to the second embodiment are shown by the shaded area in FIG. 6, and the area of the shaded area is wider than the area of the shaded area in FIG. 4 in the case of the first embodiment. .

For example, silicon carbide fibers, alumina fibers, etc. are used.

In RM, the tensile strength and coefficient of thermal expansion can be arbitrarily set by changing the blending ratio of the two types of fibers. Therefore, characteristics suitable for the use of the FRM can be obtained. Furthermore, it still has the advantages of conventional CFRAI that uses only carbon fiber as a reinforcing material (lightness, high strength).
