ｍｍ程度が好ましい。An example of the present invention will be explained in detail below with reference to the drawings. In this example, a carbon fiber-reinforced synthetic resin head of a golf club is obtained as a specific example of a fiber-reinforced thermoplastic hollow molded product. First, a hollow core surface material 1 is made by blow molding using a synthetic resin such as polyethylene, polypropylene, polyvinyl chloride, methacrylic resin, or polycarbonate as shown in FIG. This core surface material 1 has a shape almost similar to the internal shape of the hollow molded product to be manufactured, and in this example, it has a shape similar to the shape of the head of a carbon fiber reinforced synthetic resin head. The thickness of the core surface material 1 is 0.1 to 1.0
Approximately mm is preferable.

Thereafter, the pressure inside the core surface material 1 is reduced to about 10 to 100 torr. Here, a method is adopted in which the neck portion of the core surface material 1 is connected to a normal vacuum evacuation device and the inside of the core surface material 1 is evacuated through an air permeable material such as cloth. In this reduced pressure state, the heat-resistant fine particles 2 are pressurized by atmospheric pressure and solidified, and the whole is in a hard solidified state. In the present invention, the mold in this reduced pressure state becomes the medium mold 3 for molding. Therefore, in this medium mold 3, it is necessary to maintain this reduced pressure state at least until the start of pressurization, preferably until the end of molding.

A prepreg 4 made of a thermoplastic resin such as polyamide such as nylon 66 or nylon 11, polybutylene terephthalate, polyoxymethylene, polycarbonate, modified polyphenylene oxide, or polyphenylene sulfide and softened by heating is wound around the middle mold 3. This prepreg 4 is tape-shaped so that it can be easily wrapped around the medium size 3. The number of layers of prepreg is usually multiple, and the fiber direction can be changed for each layer wrapped.

This outer mold 5 has a two-piece structure, and the shape of the cavity 6 inside thereof matches the outer shape of the final molded product, here the shape of the head of a golf club. Then, the entire outer mold 5 is heated and pressurized, and further cooled in this state. By this heating and pressurization, the prepreg takes the shape of a golf club head that follows the shape of the cavity 6 of the outer mold. The conditions for this heating and pressurization are as follows:
The temperature is 150°C, the pressure is 0.5 to 5 MPa, and the time is about 1 to 10 minutes, but the temperature is not limited to this range.
It can be changed as appropriate depending on the amount of reinforcing fibers, etc.

Drain from the part. Because the filler is fine particles, this can be discharged relatively easily without the need to destroy the core material, and the heat-resistant fine particles 2 after discharge can be recovered and reused, eliminating waste. It never becomes. As a result, a hollow carbon fiber-reinforced synthetic resin head 7 made of fiber-reinforced thermoplastic plastic as shown in FIG. 4 is obtained.

When removing the core surface material 1, there are methods such as dissolving the core surface material 1 with an organic solvent, or heating it at room temperature or slightly to soften the core surface material 1 and pulling it out.

Further, in the above example, a carbon fiber-reinforced synthetic resin head of a golf club was explained as a molded product, but the manufacturing method of the present invention is of course not limited to this, and it goes without saying that it can be applied to other hollow molded products.
