    摘要: Disclosed is a process for producing a sheet-shaped prepreg which comprises: a fiber bundle introduction step in which tape-like reinforcing fiber bundles are disposed in a multilayer arrangement in the thickness direction and introduced into a die to which a molten thermoplastic resin has been supplied; a fiber bundle thickness reduction step in which each of the tape-like reinforcing fiber bundles is widened by means of spreading to reduce the thickness; a resin impregnation step in which the tape-like reinforcing fiber bundles are impregnated with the molten resin in the die; and a lamination step in which the plurality of resin-impregnated tape-like reinforcing fiber bundles are laminated in the die. Also disclosed is an apparatus for producing the sheet-shaped prepreg. It is possible to produce a high-grade sheet-shaped thermoplastic prepreg in which the resin has been uniformly and satisfactorily impregnated throughout and the reinforcing fibers have been uniformly arranged. Furthermore, the time required for resin impregnation can be considerably shortened and the productivity can be remarkably enhanced.

    摘要: The present invention relates to a method for manufacturing a large FRP member and has the following structure.
    The method for manufacturing a large FRP member, comprising the following steps (A) to (F). They are:

    setting step (A) of disposing a preform containing a reinforcing fiber base material on a surface of a molding die;
    sealing step (B) of covering a molding portion with a bagging material or a mold and providing at least one suction port and at least one resin injection port for sealing;
    evacuating step (C) of evacuating the molding portion through the suction port;
    hot-air heating step (D) of heating the molding portion by hot air;
    resin injection step (E) of injecting a thermosetting resin from the resin injection port for impregnating the reinforcing fiber base material with the resin while a temperature Tm of the molding die and a temperature Tv of the bagging material or the mold are both set to room temperature or more, and a difference ΔT in temperature between the Tm and the Tv is set to 10°C or less; and
    curing step (F) of curing the resin by maintaining the molding portion at a predetermined temperature Tpc which is equal to or more than room temperature.

    Preferably, the preform described above includes the reinforcing fiber base material and a resin distribution medium. In addition, it is preferable that in the hot-air heating step (D), the molding die be placed in a sealed chamber which is heat insulated with a heat insulating material, the hot air be circulated and supplied, and timing of starting the injection of the resin from a plurality of the resin injection ports be controlled in accordance with signals supplied from resin detection sensors provided in the molding die.
    The present invention provides a method for manufacturing a large FRP member having superior quality at an inexpensive cost and with high production yield, in which non-impregnated portions and voids are unlikely to be formed.
