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 the molded product that can be molded is limited, which is not preferable in terms of productivity efficiency, and in general, good impregnability is not obtained because the melt viscosity of the thermoplastic resin is high. When molding a new molded product without continuous fiber reinforced resin molding material, a complicated impregnation and shaping device is required at present. In addition, even if a complicated impregnation / shape forming device is used, the high melt viscosity of the thermoplastic resin does not always lead to good impregnation. However, it is not preferable in terms of productivity and efficiency.

Examples of the structure of the tape-like material used in the present invention include continuous fibers such as glass fibers, carbon fibers, aramid fibers, and fibers obtained from a heterocycle-containing polymer such as polybenzothiazole or polybenzoxazole. Further, as the thermoplastic resin, nylon 6,
Examples thereof 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, polyether ketone and the like. The reinforcing fiber and the thermoplastic resin are not particularly limited.

80% by volume is preferred. When the content of the reinforcing fiber is 20% by volume or less, the reinforcing effect cannot be effectively exhibited, and when it exceeds 80% by volume, the reinforcing fiber is not sufficiently impregnated with the resin and the porosity is less than the desired value, which is not preferable.

ら制限されるものではない。The tape-like material has a porosity of 8% or less, more preferably 6% or less. When the porosity is more than 8%, the air in the tape-like material is hard to escape, and the porosity in the fiber-reinforced thermoplastic resin molding material obtained after fusion and convergence is difficult to decrease. When used for, it is not preferable because physical properties are deteriorated. Further, the tape-like material is not limited 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 an example of a method for obtaining the fiber-reinforced thermoplastic resin molding material of the present invention. This is to supply a tape-like material from a creel, melt the tape-like material by radiant heating with an infrared heater as a heating device, and converge and shape it in water. As a heating method at this time, contact heating or convection heating can be used instead of radiation heating. After that, the shape is formed using an appropriate simple focusing / shape forming die. At this time, a roll may be used instead of the converging / shaping die.

収束比の下限は特に限定されないが実用上は０．５程度
以上である。At this time, the convergence ratio when converging the tape-shaped material is important. The convergence ratio is defined by the ratio of the cross-sectional area of the fiber-reinforced thermoplastic resin molding material after fusion convergence to the total cross-sectional area of the tape-like material to be used. If this ratio is 0.98 or more, it is in the tape-like material or between the tape-like materials. It is difficult to remove air, which is not preferable. The adjustment of the convergence ratio can be easily performed, for example, by appropriately designing the nozzle system of the entrance and exit of the convergence / shape forming 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.

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

If it is 1.5 or less, the end portion of the fiber-reinforced thermoplastic resin molding material is disturbed at the time of cutting, and if it is used for injection molding, for example, the reinforcing fiber is largely damaged and the physical properties are deteriorated, which is not preferable. On the other hand, if it is 600 or more, it is not preferable because when it is used in another molding method such as compression molding, the handling property when it is put into a mold is deteriorated.

い。It is also possible to manufacture a product having a complicated cross-sectional shape by exchanging the 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, even when it is used again for another molding, the physical properties are deteriorated due to breakage of the reinforcing fiber, which is not preferable.
