産性効率の面からも好ましいことではない。2. Description of the Related Art Various fiber-reinforced resin moldings in which a thermoplastic resin is impregnated between reinforcing fibers are commercially available. However, in many cases, the impregnation step and the shaping step are generally continuous. In such a case, the shape of a molded product that can be molded is limited, which is not preferable from the viewpoint of productivity efficiency. In addition, since the melt viscosity of a thermoplastic resin is generally high, good impregnation is not necessarily obtained. At the time of forming a new molded product without continuous fiber-reinforced resin molding material, a complicated impregnation / shaping apparatus is required at present. In addition, even if a complicated impregnation / shaping apparatus is used, good impregnation properties are not always obtained because the melt viscosity of the thermoplastic resin is high. However, this is not preferable in terms of productivity efficiency.

% Or less by heating and melting the tape-shaped material using one or more tape-shaped materials impregnated with a thermoplastic resin to a concentration of not more than 1%, and converging the tape-shaped material at the following convergence ratio. It is a reinforced thermoplastic resin molding material. R ≦ 0.98 R = S 1 / (S 2 × N) where R: convergence ratio (−) S 1 : cross-sectional area (mm 2 ) of the fiber-reinforced thermoplastic resin molding material S 2 : tape-like material Cross-sectional area per unit (mm 2 ) N: Number of tape-shaped materials supplied (-) Further, the porosity of the fiber-reinforced thermoplastic resin molding obtained in this way is 5% or less. It is also possible to shape the product into a shape such as a sphere or a tube and use the molded material directly as a molded product. It is also possible to cut the molded material into an aspect ratio of 1.5 to 600 and use it for another molding. The porosity was measured by the following method.
That is, it is a value calculated from the weight change before and after immersing in water after cutting a tape-shaped material or a fiber-reinforced thermoplastic resin molding material. Measurement method: A tape-shaped material or a fiber-reinforced thermoplastic resin molded material molded from the tape-shaped material is cut into a predetermined length (20 to 30 mm), and first, the weight before immersion in water is measured (2).
~ 3g). Next, water is put in a beaker or the like, and the above-mentioned material is immersed in the beaker, put into a vacuum dryer, and kept in a vacuum state at room temperature for 10 minutes. If there is a void in the tape-like material or the fiber-reinforced thermoplastic resin molded material molded from the tape-like material, water is permeated into the void by maintaining the vacuum. Thereafter, the object to be measured is taken out of the water, the moisture adhering to the surface is immediately wiped off, and the weight is measured. This is the weight after immersion in water. The weight before water immersion is subtracted from the weight after water immersion. This weight is the weight of the water entering the void. The porosity is determined by the following equation. Porosity (%) = (weight of material after immersion in water−weight of material before immersion in water) × 100 / weight of tape before immersion in water

定されるものではない。Hereinafter, the present invention will be described in detail with reference to the drawings, but the following drawings do not limit the present invention in any way. As the configuration of the tape-like material used in the present invention, the reinforcing fibers include continuous fibers such as glass fibers, carbon fibers, aramid fibers, and fibers obtained from a heterocyclic-containing polymer such as polybenzothiazole or polybenzoxazole. As the thermoplastic resin, nylon 6,
Examples include polyamide resins such as nylon 6.6, polyester resins such as polyethylene terephthalate and polybutylene terephthalate, polyolefin resins such as polypropylene and polyethylene, and polycarbonate, polyetherimide, polyphenylene sulfide, and polyether ketone. The reinforcing fibers and the thermoplastic resin are not particularly limited.

80% by volume is preferred. If the reinforcing fiber content is less than 20% by volume, the reinforcing effect cannot be exhibited effectively, and if it exceeds 80% by volume, the reinforcing fiber is not sufficiently impregnated with the resin, and the porosity is not less than the desired porosity.

When the porosity is larger than 8%, the air in the tape-shaped material hardly escapes, and the porosity in the fiber-reinforced thermoplastic resin molded material obtained after the convergence of the melt is hardly reduced. When used for, it is not preferable because physical properties decrease. Further, the tape-shaped material is not limited at all by its cross-sectional shape and dimensions.

りにロールを用いてもよい。FIG. 1 is a schematic view showing one example of a method for obtaining a fiber-reinforced thermoplastic resin molded material of the present invention. In this method, a tape-like material is supplied from a creel, and the tape-like material is melted by radiant heating using an infrared heater as a heating device and converged and shaped in water. As a heating method at this time, contact heating and convection heating can be used instead of radiation heating. Then, it is shaped using an appropriate simple convergence / shaping die. At this time, a roll may be used instead of the converging / shaping die.

めと考えられる。At this time, the convergence ratio when the tape-shaped object is converged is important. The convergence ratio is defined by the cross-sectional area ratio of the fiber-reinforced thermoplastic resin molding material after fusion with respect to the total cross-sectional area of the tape-like material to be used. It is difficult and undesirable to remove air. The convergence ratio can be easily adjusted by, for example, appropriately designing the inlet and outlet nozzle systems of the converging / shaping die 5 shown in FIG. still,
The lower limit of the convergence ratio is not particularly limited, but is practically about 0.5 or more. The fact that the convergence ratio is smaller than 1 means that not only the air between the tapes is removed as described above, but also the void (air) contained in the tape is removed. As shown, the porosity of the tape is 8%
Even if it is about the same degree, the effect that the porosity of the finally obtained fiber-reinforced thermoplastic resin molded product is 5% or less is produced. Although the details of the mechanism of this effect are unknown, it is considered that the resin with a small amount of voids is originally melted and pressure is applied to the resin in the nozzle by squeezing with the nozzle or the like as described above, and further the void is removed. . In addition, the fact that the lower limit of the convergence ratio is practically 0.5 or more means that the tape-shaped object is not a perfect rectangle but an ellipse or a shape similar thereto, so that the width has a caliper and the thickness has a micrometer. It is considered that this is different from the cross-sectional area measured by assuming a rectangle.

る。Although the tape-shaped material melted and converged in this way is converged and shaped in water in FIG. 1, the converging and shaping step can be performed in air. In addition, the fiber-reinforced thermoplastic resin molding obtained as shown in FIG. 1 can be used as a rod as it is,
The obtained rod-like material can be cut into a certain length and used in other molding methods, for example, injection molding, compression molding and the like.

If it is less than 1.5, the end of the fiber-reinforced thermoplastic resin molding material will be disturbed at the time of cutting, and if it is used for injection molding, for example, the reinforcing fibers will be greatly damaged and physical properties will be deteriorated. On the other hand, if it is 600 or more, when used in other molding methods, for example, compression molding, the handleability at the time of being put into a mold or the like is undesirably reduced.

い。It is also possible to manufacture a product having a complicated cross-sectional shape by exchanging a shaping die. The porosity of the obtained fiber-reinforced thermoplastic resin molding material is preferably 5% or less. If it is 5% or more, it can be used as a molded product as it is, but it is not preferable because physical properties are deteriorated due to defects and the like. Further, it is not preferable to use again for another molding, because the physical properties decrease due to the breakage of the reinforcing fiber.
