することができないことがある。The fiber reinforced metal cylindrical product molded by the hot isostatic pressing method has a diameter of 50 to 60 m because the volumetric shrinkage of the fiber reinforced metal material is large.
m is limited to those reinforced in the axial direction (0 degree), and the diameter is larger and the wall thickness is thicker than that in the circumferential direction (± 45 degrees, 90 degrees).
When molding a reinforced fiber-reinforced metal cylindrical product, breakage may occur in the reinforced fiber and the desired strength of the product may not be secured.

ことがある。The fiber-reinforced metal cylindrical product molded by the molten metal pressure impregnation method can be reinforced in the axial direction (0 degree) and the circumferential direction (± 45 degrees, 90 degrees, etc.), and has a shape and a size. However, the degree of freedom of the fiber reinforcement method is high, but when the base material is aluminum, a temperature higher than the melting point of aluminum and 760
Since pressure is applied at a high pressure of atmospheric pressure to form a composite, the strength of the fiber may be deteriorated by the molten metal and the reinforcing fiber may be displaced due to the flow of the molten metal, so that the desired strength of the product may not be secured.
