次に、上述のようにして得た軽量積層シートを用いた
複合材の製造方法について説明する。Next, a method of manufacturing a composite material using the lightweight laminated sheet obtained as described above will be described.

加熱温度に耐えて破壊されることなく基材と複合化され
る。First, the lightweight laminated sheet is placed in a molding die (not shown). Next, a molten metal of a base material (not shown) is injected into the mold. The substrate is preferably selected from the group consisting of light metals, including aluminum, magnesium, zinc, copper, brass, bronze, and light metals, including aluminum alloys, and synthetic resins. At this time, the volume ratio of the molten metal to the microsphere 3 is preferably 1 from the viewpoint of improving various properties of the composite material.
The molten metal injection amount is set so as to be 0: 1 to 10: 7. When the molten metal is injected, the microspheres 3 are heated, but withstand the heating temperature and are composited with the substrate without being broken.

すなわち複合材を得る。Further, the microspheres 3 are previously bonded to the mat 1 in a uniform distribution state, and since the mat 1 withstands the temperature of the molten metal and securely holds the microspheres 3,
The microspheres 3 are not dispersed by the injection of the molten metal, and are uniformly distributed in a substrate having a specific gravity different from that of the microspheres 3. In addition, pressure may be applied to the molten metal and / or the mold in order to promote the compounding. Then, a composite billet is obtained through a cooling step. Thereafter, if necessary, the billet is heated and subjected to various forming steps such as rolling and extrusion, and heat treatment such as quenching and annealing to obtain a final product, that is, a composite material.

に対して極めて安定になる。The microsphere 3 itself is weak to unidirectional external force and easily breaks, but once mixed into the base material as described above, the external force applied to the microsphere 3 is mutually spherical due to its spherical shape. As a result, the microspheres 3 become extremely stable against external forces.

でかつ強度が大きく、しかも制御性，断熱性に優れる。Further, since the internal gas expands and contracts in accordance with the thermal expansion and thermal contraction of the base material, the thermal stability is high. As a result, the microspheres 3 are stable during the production of the composite billet and in various subsequent molding steps, and are hardly broken and disappear in the base material. The composite material in which the microspheres 3 are mixed and compounded is lightweight, has high strength, and is excellent in controllability and heat insulation.

In this case, substantially the same effect as the hollow microspheres is obtained. Is obtained. That is, the weight can be reduced in accordance with the difference in specific gravity between the base material and the microsphere, the strength is increased by the microsphere, and the vibration damping action due to the difference in rigidity between the base material and the microsphere is reduced.

料としての性状を付与するようにしても良い。Further, the microspheres 3 can be subjected to a surface treatment. More specifically, a coating made of any constituent material selected from the group of aluminum, zinc, copper, silver, iron, ferrite, etc. is formed on the outer surface of the microsphere 3 and the microsphere 3 itself is formed. As a result, the strength of the composite material may be increased, and preferably, the composite material may be given properties as a multifunctional material.

合物の成形性および複合材の強度を向上できる。In this case, in producing the composite material, the microspheres 3 are cleaned, then floated and dispersed in a vapor deposition chamber, and a coating is formed on the surface of the microspheres by vapor deposition. At this time, when the same material or similar material as the base material 1 is used as the film constituting material, the wettability of both materials, and furthermore, the moldability of the mixture and the strength of the composite material can be improved.

膜を形成したマイクロスフィアーを用いる。Further, a material having a different electromagnetic property, such as conductivity, from the base material can be used as the film constituting material, and the properties as a multifunctional material can be contributed to the composite material as a whole. For example, when a non-magnetic substrate is used, a magnetic film is formed on the microsphere, or a microsphere on which a good conductive film is formed together with a low conductive substrate is used.

の後、これを固化して上述と同様のビレットを得る。In producing the composite material, a base material powder may be used instead of the base material melt. In this case, the base powder is put into a molding die provided with the lightweight laminated sheet. The amount of the base material charged is preferably 10: 1 which is a preferable lower limit value for the weight ratio of the composite material to the volume ratio of the base material and the microsphere to a preferable upper limit value from the strength aspect 10: Set to 7
Next, heating is performed to a temperature at which at least a part of the base material is fluidized and the base material and the lightweight laminated sheet are composited. Thereafter, this is solidified to obtain the same billet as described above.
