Problems solved by technology

[0014] On the other hand, the RTM method using a bag material as disclosed in Patent Document 2 has the problem of consuming a lot of manufacturing time and labor because it needs to be sealed with a bag material every time a molded product is molded; In addition, since the bag material and the sealing material for sealing need to be discarded each time in each molding cycle, there is a problem of not only waste of material but also high cost

Abstract

The present invention provides a method for manufacturing fiber-reinforced plastic and a device for manufacturing fiber-reinforced plastic used in the method. A preform with a three-dimensional shape, and an inner mold that can move in a lateral direction different from the up-down direction, inject the matrix resin into the preform under the condition that the thickness of the preform is greater than the thickness of the molded product to be obtained Impregnated in the body, and then, while at least one of the upper mold or the lower mold is moved to the other, the inner mold is moved in the lateral direction to pressurize the preform, thereby controlling so that the preform The thickness becomes the thickness of the specified product, and then, heating is performed to cure the matrix resin to obtain a molded product.

Description

technical field [0001] The present invention relates to a method and device for manufacturing fiber reinforced plastics (hereinafter sometimes abbreviated as FRP), and more particularly to a method and device for manufacturing fiber reinforced plastics for manufacturing thick-walled and three-dimensional FRP. In the case of molded products, the state can be easily controlled while making the fiber volume content (hereinafter sometimes abbreviated as Vf) high, and can be manufactured by the RTM (Resin Transfer Molding) method using a simple device FRP molded products that require high-quality structures such as aircraft parts. Background technique [0002] As a method for producing FRP, the following RTM method using an upper mold and a lower mold is known, that is, a reinforcing fiber base material is placed in a cavity formed by the upper mold and the lower mold, the mold is pressed to close the mold, and the The pressurized matrix resin is injected into the reinforcing fi...
