- Patent Document 2 discloses a molding method in which seal portions for controlling the resin flow are provided on both side portions in the direction in which the resin flows, and the resin is injected from the outer peripheral side of the cavity.
- Resin (arrow) is injected from a plurality of injection ports 3 arranged within the range, but it takes a relatively long time for the resin from each injection port 3 to reach the entire preform 1, and resin impregnation is performed. There is a problem of being slow.
- the preform 1 is arranged on the outer peripheral side. Resin (arrow) is injected from the injection port 4, but again, it takes a relatively long time for the resin from each injection port 4 to reach the entire preform 1, and there is a problem that resin impregnation is slow.
- Patent Document 3 is cited as a document related to the present invention.
- an RTM method using the temperature during molding as a parameter is shown, but the temperature distribution in the mold is positively controlled. No attempt is made to do so. In other words, it is not intended to increase the speed of resin impregnation actively, nor is it intended to achieve both higher speed of resin impregnation and improved quality of molded products.
- an object of the present invention is to achieve both improvement in the speed of resin impregnation and improvement in the quality of a molded product by adding improvements not expected in the prior art to the RTM method for injecting resin from a plurality of injection ports. There is.
- the RTM method according to the present invention includes a preform formed from a reinforcing fiber base in a cavity of a mold, and a resin is injected into the cavity from a plurality of injection ports.

- the resin flow itself moves in the direction of extending the reinforcing fibers constituting the preform from the inside to the outside in the case of, for example, a woven fabric.
- the eye twist can be appropriately suppressed.
- the criteria for the occurrence of the eye twist is derived from the material configuration of the preform, and the effect of suppressing eye twist can be expected by appropriately applying the present invention within the scope of the present invention.
- the injection port closing timing after resin injection is, in particular, closing the injection port arranged at the first position before the injection port arranged at the second position. It is preferable.

In this way, it is possible to concentrate the final sink caused by the curing shrinkage of the resin on the outer peripheral side, and a product form that does not cause sinking more reliably in the central part of the molded product where design is required. It becomes feasible. In particular, this is a particularly effective technique in the case where a part that is outside the product range of the final molded product is initially set on the outer periphery of the preform and the part is removed from the molded product after molding.
- the resin injection flow rate or injection pressure at the initial stage of injection before the resin filling into the preform is completed in order to suppress eye twist. Since the flow front becomes small at the final impregnation point of the resin, the pressure is likely to increase rapidly, and the risk of occurrence of eye misalignment increases, it is possible to suppress eye misalignment by applying such a method.
- the resin pressure may be applied to the cavity from the inlet arranged at the second position or the pressure supply source arranged near the inlet. preferable.
- the resin pressure is applied from the outer peripheral side of the part, it is avoided that the part becomes a negative pressure as the resin cures, and the occurrence of sink marks accompanying the curing shrinkage is also avoided.
- the resin applied in the cavity from the injection port arranged at the second position or the pressure supply source arranged near the injection port It is also preferable to increase the pressure.
- the resin at the site tends to flow along with the curing shrinkage, but the resin can be supplied and replenished from the outer periphery side intentionally and efficiently with respect to the resin flow during the curing shrinkage. It becomes possible to suppress or prevent the occurrence of accompanying sink marks.
- the method of injecting resin into the cavity from a plurality of injection ports is not particularly limited, but the pressure in the cavity is reduced in advance, and the resin is injected into the reduced pressure cavity. Is preferred. In this way, it is possible to satisfactorily impregnate the resin over a wide range of the preform.
- resin is injected from both the injection port arranged at the first position in the central portion of the cavity and the injection port arranged at the second position in the outer peripheral portion of the cavity.

- the temperature of the injected resin is a thermosetting resin
- the injection resin is a thermosetting resin
- vacuum forming in which a resin is injected into a cavity that has been depressurized in advance, there is a possibility that it is not necessary to consider voids at the resin joining portion from both injection ports.
- the portion from the injection port 14 to the preform 11 is set to be equal to or less than the thickness of the molded product, the amount of the waste resin after molding can be reduced. Furthermore, when a highly reactive resin is used, the thickness of the resin alone is reduced, and the effect of suppressing the reduction of pot life due to self-heating can be expected. Moreover, the influence on the area
- Other methods for suppressing the above-mentioned misalignment include a method in which the flow in the center is dominant compared to the outer periphery.
- the occurrence of eye twist is caused by the flow from the outer peripheral portion toward the central portion, and the flow from the central portion toward the outer peripheral portion is in a direction in which the eyes of the preform are stretched and hardly occurs. Therefore, this invention can be utilized also for suppression of eye twist.
