Description of the Related Art In recent years, a so-called "composite material", which is a composite of two or more kinds of materials in a form utilizing their excellent functions, has been attracting attention. As such a composite material, for example, fiber reinforced plastic (FRP) is well known and is used in a wide range of fields from leisure goods and sports goods to aircraft and space industry equipment.

That is, first, carbon fibers, glass fibers, aramid fibers, etc. are formed into a woven fabric, a non-woven fabric, etc., cut into a sheet shape, a tape shape, etc., and then impregnated with a resin to obtain a prepreg. As shown in FIG. 2, the prepregs are laminated as they are, and along a predetermined mold 1, as shown in FIG. 2, the prepreg 2 on the mold 1 is covered with a vacuum bag 3 without any gaps and then placed in the autoclave 4. Load it.
Then, in the autoclave 4, the heater 5 and the blower 6 are operated, hot air is circulated as shown by an arrow P, and the inside of the vacuum bag 3 is evacuated by the vacuum pump 8. The prepreg 2 is cured while deaerating the air existing at the interface between the prepreg 2 and the mold 1. And autoclave 4
The desired FRP molded product can be obtained by taking out the cured product from the mold and removing it from the mold 1.

るため、その改良が強く望まれている。However, as described above, in the curing method using the autoclave 4, the prepreg 2 along the mold 1 must be put in the vacuum bag 3 and sealed. There is a problem that the work is very complicated. In particular, when the molded product to be obtained is small, as shown in FIG. 3, a large number of prepregs 2 are loaded side by side in an autoclave 4 and are collectively cured, but at this time, Since each prepreg 2 along the mold 1 must be individually sealed with the vacuum bag 3 and connected to the vacuum pipe 9, which requires a great deal of work, its improvement is strongly desired.

Therefore, according to this method, unlike the conventional method using an autoclave, it is not necessary to individually seal each prepreg with a vacuum bag, and the processing efficiency can be greatly improved. Moreover, in the conventional method,
Since the degree of sealing by the vacuum bag varies from prepreg to prepreg, some prepregs may be cured with insufficient deaeration, resulting in uneven quality. However, according to the present invention, a plurality of prepregs may be used. This is advantageous in that the quality of the obtained cured product becomes uniform because the pressure reduction, heat and pressure treatment are performed under the same conditions.

First, the prepregs 2 along the mold 1 are placed on each tray 21 of the inner tank 18 at predetermined intervals, and the trays 21 are multi-tiered on the base 20 to open the upper surface of the uppermost tray 21. The lid 22 is fitted to and the whole is fixed. Then, the inner tank 18 is loaded into the processing tank 10 and fixed to the inner tank support 16. In this state, the lid 11 is closed to seal the inside of the processing tank 10, and the vacuum pump 29 is operated to open the vacuum valve 26 to depressurize the inside of the processing tank 10. As a result, in the inner tank 18, the air contained in the prepreg 2 itself and the prepreg 2
And the air existing at the interface of the mold 1 are sufficiently degassed. Next, the vacuum valve 26 is closed to stop the vacuum pump 29, and the pressurizing valve 31 is opened to open the compressor 32.
Is operated to increase the pressure inside the processing tank 10. At the same time, the heat exchanger 13 and the blower 14 are operated to change the pressurized air flow into hot air and circulate it as shown by arrow A. That is, the pressurized flow is blown into the heat exchanger 13 by the blower 14, heated to a predetermined temperature by the heat exchanger 13, and then flows into the header portion 19 of the inner tank 18,
The inside of each tray 21 of the inner tank 18 rises, is jetted from the cover plate 22, descends along the inner peripheral surface of the treatment tank 10, and is returned to the suction port side of the blower 14. As a result, the hot air forcedly circulated and the prepreg 2 in the inner tank 18 repeatedly come into contact with each other, and the prepreg 2 is cured. After holding this state for a certain period of time,
The release valve 33 is opened to return the inside of the processing tank 10 to normal pressure, and the lid 1
1 is opened and the inner tank 18 is taken out of the processing tank 10. Then, the cured body of the prepreg 2 is taken out from each tray 21 together with the mold 1, and then the mold is removed. The cured products thus obtained are uniformly cured in a state of being sufficiently deaerated, have high quality, and are widely used in various fields.
