Abstract:
1. A method of manufacturing a fiber reinforced plastic structure, the method comprising: preparing a first mold and a second mold, wherein the second mold is configured to form a cavity with the first mold and has a plastic supplying unit through which a plastic is to be supplied; providing a fiber laminate on the first mold; providing a plastic flow medium and a plastic flow suppressing member on the fiber laminate, wherein the plastic flow medium has a mesh structure of meshes for increasing a flow volume of the plastic to be impregnated to the fiber laminate, the plastic flow suppressing member is a sponge, and the plastic flow suppressing member is provided on or below the plastic flow medium so that one part of the meshes of the plastic flow medium is blocked; covering the fiber laminate, the plastic flow medium and the plastic flow suppressing member on the first mold with the second mold to form the cavity between the first mold and the second mold; depressurizing the cavity; supplying the plastic from the plastic supplying unit at a depressurized state, so as to impregnate the plastic to the fiber laminate while suppressing a flow of a flow front of the plastic along a side of the plastic flow medium with the plastic flow suppressing member which is crashed at the depressurized state; curing the plastic so as to produce a plastic impregnated and cured fiber laminate as the fiber reinforced plastic structure; and removing the plastic flow suppressing member and the plastic flow medium from the fiber reinforced plastic structure, wherein the plastic flow suppressing member and the plastic flow medium are different products.
