強化金属複合材料の製造方法に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for manufacturing composite materials, and in particular, a method for manufacturing composite materials, in which a suitable number of preforms made of metal as a base material and fiber as a reinforcing material are stacked together and easily deformed at high temperatures. The present invention relates to a method for manufacturing a fiber-reinforced metal composite material in which the material is rolled using sandwich rollers.

Generally, fiber-reinforced metal is a composite material that has a metal matrix and is reinforced using ceramics such as boron, silicon carbide, and alumina. Techniques for producing sheet materials and plate materials using this type of metal composite material include the press method, which performs pressure forming at high temperatures, and the rolling method, in which the preform is sandwiched between flat jigs made of stainless steel plates that are resistant to deformation at high temperatures. A roll forming method is known.
このうち、プレス法は加工物の寸法がプレスの
プラテンの寸法によつて制限され、特に長尺物の
金属複合材料の製造ができないという問題を有し
ている。 Among these methods, the pressing method has the problem that the dimensions of the workpiece are limited by the dimensions of the press platen, and in particular cannot produce long metal composite materials.

題があつた。 On the other hand, in the roll forming method, if the flat plate jig is thin, stress may concentrate on the brittle reinforcing fibers and cause the fibers to break, so a thick flat plate jig is inevitably used. As a result, it is heavy and has poor workability, and furthermore, since it takes a long time to heat, the reaction between the fibers and the matrix metal is promoted, making it impossible to obtain the properties of a composite material.
そこで、本発明の目的はロール成形法におい

Therefore, the purpose of the present invention is to solve the problems of the above-mentioned conventional techniques in the roll forming method, shorten the heating time, and reduce the weight of the processing equipment without using a flat plate jig, thereby improving workability. An object of the present invention is to provide a method for manufacturing a long metal composite material.

In order to achieve the above object, the present invention uses metal as a base material, is reinforced with reinforcing fibers, and wraps the outside of a plurality of stacked preforms with a pack material that easily deforms at high temperatures, and after heating to a predetermined temperature. This is characterized in that the reinforcing fibers of the preform are rolled by passing between an upper roll and a lower roll along the running direction.
以下本発明による複合材料の製造方法の一実施

ば放出したガスを吸収することができる。 In FIG. 1, reference numeral 1 indicates a preform, and this preform 1 is in the form of a sheet or wire, which is made of a metal such as an aluminum alloy as a base material and subjected to prepreg treatment using fibers such as carbon fiber or silicon carbide fiber as a reinforcing material. It is a semi-finished product.
These preforms 1 are generally laminated. For example, to manufacture a composite material with a plate thickness of 2 mm, approximately 220 C/Al ion plating preforms with a thickness of 10 μm are required, and 5 sheets are required for SiC/Al wire preforms with a wire diameter of approximately 0.5 mm. It is necessary to stack the layers. The preform 1 is surrounded by a pack material 2 made of a material, for example aluminum, which is more easily deformed plastically than the matrix material at high temperatures. The material of the pack material 2 is not limited to aluminum, but a thin metal plate with a thickness of about 0.8 mm can be used. Thereafter, the preform is heated to a predetermined temperature just below the solidus temperature of the matrix metal constituting the preform. The method of wrapping the preform 1 with the packing material 2 is to wrap the preform 1 in such a manner that the front and rear ends are open in the threading direction A, as shown in FIG. It is preferable that the sheet passing direction A and the sheet passing direction A are made to coincide with each other. In addition, if it is necessary to prevent oxidation of the base metal, as shown in Figure 2, the preform 1 is sealed with a pack material 2 by electron beam welding, and cavities 3, 3 are formed at both ends. In addition, gas generated from the preform 1 during pressure molding may be released into the cavity 3 so that the pack material 2 is easily plastically deformed. Note that if a getter such as magnetic powder is placed in the cavity 3, the released gas can be absorbed.
さらに、上記被加工物であるプリフオーム１と
パツク材２との間に潤滑剤４を介在させると、境
界面における摩擦係数を極少にし軟質材が塑性変

るうえで効果的である。 Furthermore, by interposing the lubricant 4 between the preform 1, which is the workpiece, and the pack material 2, the coefficient of friction at the interface is minimized, and when the soft material undergoes plastic deformation, it is transmitted to the preform, the workpiece. This is effective in suppressing the tensile stress generated and preventing tensile breakage of fibers.

and then rolled under a predetermined pressure. Since the running direction of the reinforcing fibers in preform 1 is the same as the feeding direction along the threading line, the workpiece is only subjected to a load in the thickness direction that enables matrix densification and diffusion bonding. This makes it possible to mold metal composite materials using rollers that do not cause fiber breakage.

等に有効であることが確認された。 FIGS. 4 and 5 show an experimental investigation of the relationship between forming temperature and strength using a SiC/Al wire preform as an example. FIG. 4 shows the fiber direction and rolling direction of the workpiece before roll forming, and roller forming was performed along this rolling direction. Figure 5 shows the results of comparing the tensile strength of metal composite materials formed by roller forming using the conventional roll forming method using a jig and the roll forming method according to the present invention without using a jig. It is something. It was confirmed that there was no significant difference in the tensile strength properties of each, and the molding method according to the present invention was as effective as the conventional molding method.

As is clear from the above description, according to the present invention, the outside of the preform is wrapped with a pack material that easily deforms at high temperature, and after being heated to a predetermined temperature for a short time,
Since this pack material is rolled directly through the upper and lower rolls, heating time can be shortened and roll forming can be performed without using heavy flat plate jigs.As a result, processing equipment such as flat plate jigs and rolling rolls can be made lighter. It is possible to improve the workability and obtain a long metal composite material.
