ことを見出した。The inventors of this paper conducted various experimental studies in view of the above-mentioned problems in the conventional pressure casting method, and found that the above-mentioned buckling deformation of the fiber reinforced material is caused by the molten metal introduced into the mold. In the process of solidifying the matrix metal while being pressurized by the plunger element, the tip of the same phase that solidifies and grows substantially perpendicular to the casting wall plunges. This is caused by the elements being pressed against the fiber reinforced material, and therefore, in order to avoid such buckling deformation of the fiber reinforced material, it is necessary to It has been found that it is necessary to configure the mold cavity of the mold with a pressurizing chamber and a molding chamber, and to appropriately set casting conditions such as the amount of molten matrix metal introduced, so that this occurs.

Regarding the solidified body (), a structure with a disordered crystal growth direction was observed near the part where the buckling deformation of case 12 occurred, and it is therefore assumed that the molten matrix metal finally solidified in this part. On the other hand, for those where the ratio Vt/Vt of the volume of molten metal in the pressurizing chamber to the volume of the molding chamber is 06 or more, the disordered structure in the crystal growth direction is not observed in the vicinity of case 12, It was recognized that the solidified portion was present in the pressurized chamber 3.

The mold tension of the mold is composed of a molding chamber and a pressurizing chamber, and the ratio of the volume of molten metal in the filling chamber to the volume of the molding chamber is substantially 0.6 or more. It has been found that it is preferable to carry out the casting using a molten matrix metal of .

ことを特徴とする複合材料部材の一造方払。A mold having a pressurizing chamber that receives only molten matrix metal, a molding chamber that communicates with the pressurizing chamber and receives the reinforcing material and the molten matrix metal, and pressurizing the molten matrix metal introduced into the pressurizing chamber and the molding chamber. The reinforcing material is heated to a temperature higher than the melting point of the matrix metal using a casting machine having a pressurizing means for applying pressure. The volume ratio of molten matrix metal in the pressurized chamber is substantially 0.6
A composite material member characterized in that a molten matrix metal is introduced into the pressure chamber and the molding chamber, and the molten matrix metal is solidified while being pressurized in the pressure chamber and the m-shaped chamber. One-way payment.
