った。Conventionally, for example, arms as aircraft parts have generally been made of aluminum alloy, but they are still relatively heavy and do not have a sufficiently high tensile strength. In particular, in aluminum alloy arms with spherical sliding bearings, the stainless steel spherical sliding bearing is attached by press-fitting, so it is necessary to drill a hole into which the bearing is fitted, and when fitting the bearing, it is necessary to drill a hole into which the bearing is fitted. Since stress is generated in the periphery of the hole, there is a drawback that the wall thickness of the arm at the periphery of the hole must be increased to accommodate this stress.

て繊維と樹脂を選定してＭ１合せれば耐食性。Table 1 Table 2 Table 3 From Table 1, the tensile fracture strength of the CFRP arm is 8?00k.
g is 3.0 times that of the aluminum alloy arm, and Table 2
The smaller 111 ratio of the CFRPjJ arm is 0.53 times that of the aluminum alloy arm, and it is also 47% lighter than the aluminum alloy arm. Also, if the strength of the circumferential surface of the sphere of the spherical plain bearing is made the same as that of the CFRP arm and the aluminum alloy arm, the song title will be 1/2 of the latter! l! becomes. Furthermore, from Table 3, CF
The static friction coefficient of the spherical plain bearing of the RP arm is also 0.08.
It is quite low, about the same as tetrafluoroethylene, and the E-ray strength of the bearing part is also high at 80 kg/am. Furthermore, the coefficient of dynamic friction of the spherical plain bearing is extremely low because the carbon #a fibers are directly exposed on the spherical surface that is in contact with the sphere. As mentioned above, the CFRP arm has better properties in various respects than the aluminum alloy arm.In this way, according to the first invention, the spherical bearing surface of the spherical plain bearing is made of fiber-reinforced plastic along with the arm water body. Since it is constructed by integrally molding the ball, the structure is simple as only the sphere is rotatably embedded in the arm, and it is light and quick.
The tensile strength of 11 is 7+, and if you select the fiber and resin according to the usage conditions and match M1, it will be corrosion resistant.

る。It has improved low temperature resistance and #fatigue resistance, and can be used as parts for equipment such as aircraft and spacecraft that are used under very harsh conditions.According to the second invention, prepreg can be wrapped around the circumferential surface in the middle of stacking the prepreg. Since the spherical bearing surface of the spherical sliding bearing is integrally molded by intervening the attached sphere, there is no need to drill a hole in the arm for fitting the bearing as in conventional arms with spherical sliding bearings. Fitting is unnecessary and stress concentration does not occur due to this, and the peripheral surface of the bearing is sufficiently thin and the arm can be made lighter.
