第１図は本発明の繊維強化金属製円筒体の製造装置の一
例を示す。同図を用いて該円筒体の製造方法を以下に説
明する。(Example) FIG. 1 shows an example of an apparatus for manufacturing a fiber-reinforced metal cylindrical body of the present invention. The method for manufacturing the cylindrical body will be explained below using the same figure.
溶融金属１を噴霧器２を通過させて金属粒子３を噴霧状
に噴射する。この金属粒子３は外気に触れて急冷され半
溶融、半凝固の状態になる。噴霧器２の下方には駆動機
構４によって回転しているマンドレル５が配されており
、噴霧状に噴射された金属粒子３はこのマンドレル５上
に堆Ｉする。Molten metal 1 is passed through an atomizer 2 to spray metal particles 3 in the form of a spray. The metal particles 3 are rapidly cooled when exposed to the outside air and become semi-molten and semi-solid. A mandrel 5 rotated by a drive mechanism 4 is disposed below the sprayer 2, and the metal particles 3 sprayed in the form of a spray are deposited on this mandrel 5.
マンドレル５は回転しているので金属粒子３は円筒状に
堆積し円筒体６を形成することとなる。金属粒子３の堆
積の厚さが予め設定した厚さに達したときに、繊維７を
円筒体の軸方向に沿って円筒体６の表面に並べて巻きつ
けられる。巻きつけの回数により円筒体の強度が異なっ
てくるので、巻きつけの回数は所望の強度にてらして決
定する。Since the mandrel 5 is rotating, the metal particles 3 are deposited in a cylindrical shape to form a cylindrical body 6. When the thickness of the deposited metal particles 3 reaches a preset thickness, the fibers 7 are arranged and wound around the surface of the cylinder 6 along the axial direction of the cylinder. Since the strength of the cylindrical body varies depending on the number of times of wrapping, the number of times of wrapping is determined based on the desired strength.

ものの断面図であり、繊維７を複数回巻きつけたときは
、このように金属中に繊維７が層状に配列されるのが好
ましい。Metal particles 3 are placed on the surface of the cylindrical body 6 wrapped with mAl1.
The spraying is continued to deposit metal particles 3, thereby forming a cylindrical body 6 having a desired thickness. A cross-sectional view of this cylindrical body 6 is shown in FIG. This figure is a cross-sectional view of the fiber 7 wound in three rows radially outwardly, and when the fiber 7 is wound multiple times, it is preferable that the fiber 7 be arranged in layers in the metal like this.

５０ ｋｇ／ ｍｎ＋２）、アルミナ繊維（同１６０ｋ
ｇ／ｍｍ’）、ｃＦ＠維（同２５０ ｋｇ／ ＋ｎｍ’
）が適している。The fibers used include, for example, 5iCl fibers (bow tensile strength 2
50 kg/mn+2), alumina fiber (160 kg/mn+2)
g/mm'), cF@fiber (250 kg/+nm')
) is suitable.
