。(Prior Art) In recent years, fiber-reinforced resin molding materials have been used as outer panel materials for automobiles, for example, in place of conventional steel plates from the viewpoint of weight reduction, energy saving, and cost reduction. Conventional automotive exterior skin materials have generally been fiber-reinforced thermosetting resin molding materials created by impregnating fiber reinforced materials with thermosetting resins; Recently, fiber-reinforced thermoplastic resin molding, which is obtained by impregnating fiber reinforced material with thermoplastic resin, has been used as a material to compensate for these drawbacks. Materials are attracting attention.

提案されている。By the way, conventionally, in manufacturing the fiber-reinforced resin molding material (prepreg), a manufacturing method using a pultrusion type manufacturing apparatus shown in FIG. 4, for example, has been proposed.

料が製造されるようになっている。As shown in FIG. 5, the head block 5 of the die 20
A fiber passageway 14 through which the fiber bundle 4 passes from above to below is provided inside the head block 5 so as to pass through the fiber passage 14 in a long vertical direction. A flow path 10 is introduced, and the resin flow path lO and the fiber passage path 14 communicate with each other within the head block 5, and a manifold 7 is formed at the joint portion thereof. Manifold 7
A nozzle portion 8 is formed in the earthen wall portion of the manifold 7, and a die lip 9 having a die outlet 9a is provided at the lower end of the manifold 7. When the fiber bundle 4 passes through the fiber passage 14 from above the die 20 and is taken up by the cooling roll 6, the molten resin a adheres to or impregnates the fiber bundle 4 in the manifold 7, and the fiber The entire bundle 4 is taken out from the die outlet 9a and cooled there to produce a fiber-reinforced resin molding material.

。However, since the wettability between the fiber bundle 4 and the molten resin a is generally poor, in the pultrusion type manufacturing method having the above configuration, the molten resin a only adheres to the periphery of the fiber bundle 4, and the molten resin a is The fiber bundle 4 cannot be sufficiently impregnated. In order to increase the impregnation of the resin into the fiber bundle 4,
A pre-impregnation method has been proposed in the past in which the fiber bundle 4 is impregnated with a resin in the form of a solution or emulsion, but this method causes environmental hygiene problems because the solvent etc. evaporate, and also causes problems such as energy loss. I don't like it.

程が複雑化し、製造コストの面で改良の余地があった。(Problem to be Solved by the Invention) However, according to the above-mentioned method of pre-adhering resin powder, a process of powderizing the resin to be applied to the fiber bundle, a resin impregnation tank, etc. are required. The manufacturing process has become complicated, and there is room for improvement in terms of manufacturing costs.

供給圧力を上げる上記方式を採用することはできない。Also, when impregnating the fiber bundle with thermoplastic resin,
Since the thermoplastic phase has a much higher viscosity when melted than that of the thermosetting resin, it is difficult to impregnate it into the spaces between the individual filaments of the fiber bundle. It is possible to improve the impregnation properties of the resin by increasing the melting temperature of the resin to improve its fluidity, but if the melting temperature of the resin is set too high, the resin will It has the disadvantage of causing thermal deterioration, decreasing the strength of the matrix resin itself, and ultimately impairing the performance of the molded product.Furthermore, by increasing the supply pressure of the molten resin, it is possible to increase the impregnation of the molten resin into the fiber bundle. However, since the fiber bundle is continuously introduced into the manifold provided in the die, the manifold needs to be opened to the outside, so the above method of increasing the resin supply pressure is not recommended. It cannot be adopted.

て該繊維束４はダイ出口９ａから下方へ引き出される。(Function) While the molten resin a is being supplied to the manifold 7,
When the fiber bundle 4 is continuously supplied to the fiber passageway 14 of the head block 5, the molten resin a adheres to the periphery of the fiber bundle 4 and impregnates into the fiber bundle 4, and the cooling roll 6 is driven to rotate. The bundle 4 is drawn downward from the die outlet 9a.

押し込まれることになる。Here, since the pressure member 11 presses the side surface of the fiber bundle 4 in the molten resin a, the fiber bundle 4 is pushed by the pressure member 11 and expanded, and the fiber bundle 4 and the molten resin a are separated. At the same time, the molten resin a existing around the fiber bundle 4 is forced into the fiber bundle 4. By pushing the molten resin a, the air present between the fibers of the fiber bundle 4 is expelled, and the molten resin a adheres around the single fibers of the fiber bundle 4. In particular, the pressure members 11 are arranged alternately on the front and back surfaces of the strip-shaped fiber bundle 4 along the moving direction of the fiber bundle 4, so that the molten resin a is applied to the fiber bundles 40 from both the front and back surfaces alternately and multiple times. It will be pushed into bundle 4.

is taken up by a cooling roll 6 disposed below the die 20 and cooled there to produce a fiber-reinforced thermoplastic resin molding material (prepreg). The obtained fiber-reinforced resin molding material is used as a one-way reinforcing material or a two-way reinforcing material depending on the fiber direction of the fiber bundle 4 used.

Bidirectional reinforcement materials are mainly used for automobile hoods, roofs, decks,
It can be used for all skin panels, including doors and girders that support aircraft wings.

することができる。(Effects of the Invention) As described above, according to the present invention, when the fiber bundle is impregnated with the molten resin, the sides of the fiber bundle are pressed.
Because the pressing force allows the molten resin present around the fiber bundle to be pushed into the fiber bundle at the same time as defibration, it is possible to improve resin impregnation. Furthermore, since the impregnating properties of the resin can be increased without particularly raising the melting temperature of the resin, thermal deterioration of the resin and reduction in strength of the molded product are not caused. Furthermore, the apparatus of the present invention can improve the impregnation of the resin as described above with a simple configuration of just providing a pressure member in the head block of the die, so it is possible to improve the impregnating property of the resin as described above. There is no need for a resin impregnating tank or the like, which simplifies the manufacturing process and reduces production costs.
