。As the reinforcing material, a fiber material such as glass fiber, a wire material, or a combination thereof is used. The mandrel may be of any combination of straight or tapered rod or circular or polygonal cross-section, depending on the required product shape (see FIG. 11). First, in the synthetic resin injection step 7 described in connection with FIG. 1, a predetermined amount of liquid synthetic resin is injected into the pedestal 21 in advance. (See Figure 9A) The injection volume depends on the required product dimensions. The synthetic resin is preferably thermosetting, such as unsaturated polyester resin, epoxy resin, phenol formaldehyde resin, or polyimide resin. As shown in FIG. 9B, the mandrel 11 is smoothly inserted into the receiving mold 21 until its tip reaches the liquid synthetic resin injected into the receiving mold 21, but after that, the mandrel 11 is inserted into the receiving mold 21. Resistance due to buoyancy and viscosity gradually increases,
With normal press-fitting loads, it becomes difficult to insert more mandrel.
そこで、本発明の方法においては、心金の挿入時または
圧入時に心金または受け型２１に相対的に振動を加える
ことによつて心金の圧入の円滑化を図つている。Therefore, in the method of the present invention, the press-fitting of the mandrel is made smoother by applying relative vibration to the mandrel or the receiving die 21 when inserting or press-fitting the mandrel.

樹脂の含浸を促進する。As for the form of vibration, longitudinal vibration is more effective than transverse vibration in the longitudinal direction of the mandrel or receiver mold. As shown in Figure 10, the tendency of the vibration press-fitting effect is as follows: The insertion time (minutes) of the mandrel is plotted on the x-axis, and the insertion pressure (Kg/d) of the mandrel is plotted on the x-axis.
When taken on the Y axis, it shows a tendency to form one side of a hyperbola with the X and Y axes as asymptotes. And when the frequency and amplitude are within the optimal range, the eccentricity is minimized,
It is expected that the eccentricity will further increase when outside the optimum range, and that the eccentricity will be at its maximum when no vibrations are applied. In summary, the vibration press-fit effect is
Not only can the insertion pressure and insertion time of the mandrel be reduced, but the defoaming effect in the synthetic resin promotes homogeneous resin impregnation.
