Description of the Related Art At present, for FRP products requiring high mechanical strength, such as the body of an aircraft tank, continuous long fibers having high tensile strength are arranged so as to receive stress in the tensile direction. The so-called filament winding method (FW method) is used. In this method, the fiber is wound around a rotating mandrel while applying a certain tension at a predetermined winding angle in order to arrange the fiber in a direction in which the main stress acts. At that time, in order to fix the fiber in a wound state, the fiber is impregnated with a resin melted in a liquid state, then wound around a mandrel, and the resin-impregnated fiber wound around the mandrel is cured to complete the desired molding. In the step of impregnating fibers with a liquid resin, an apparatus shown in FIG. 6 is used. In this apparatus, a pair of guide rollers 3 is disposed between a delivery roller 1 wound with fibers A before resin impregnation and a mandrel 2, and a main roller 5 is provided between the guide rollers 3. The fiber A is guided into the resin tank 4 and immersed in the resin B melted in a liquid state in the resin tank 4.

あった。However, the resin B melted in a liquid state contains air bubbles, and when the fiber A is impregnated with the resin B as it is, the resin B hardens even after the resin B is cured. There is a problem that air remains in the resin B and reduces the strength of FRP. In order to solve such a problem, there is a method in which the resin and the fiber are put in the same container, the pressure is reduced, and the air inside the resin is extracted by making the outside of the resin a negative pressure. Has a disadvantage that the air removal operation must be performed in a separate step, and cannot be performed continuously with other manufacturing steps, resulting in a significant decrease in productivity. Further, in the impregnating apparatus, since the fiber A is bent at a steep angle by the guide roller 3 and the main roller 5, there is a problem that the fiber A is easily broken.

The liquid can be impregnated while the object is sent in a certain direction, and the object to be impregnated does not need to be bent, and can be processed continuously with other steps. In addition, at least one of the planar members moves in the direction opposite to the feeding direction of the impregnation target, and the interval between the planar members is formed such that the upstream side in the moving direction of the planar member is small and the downstream side is large. Therefore, the liquid between the planar members flows from a small portion of the flow path cross section to a large portion thereof. As a result, the pressure of the liquid between the planar members decreases, and air is removed from the liquid between the planar members.

内全域に亘って負圧となる。At this time, the resin B flowing between the guide plate 13 and the endless belt 10 flows from a portion having a small cross section of the flow channel to a portion having a large flow channel cross section.

a, the height of the gap on the outlet side of the flow path is Hb, and the distance x from the inlet of the flow path is x
Assuming that the height of the gap near the outlet is H, the moving speed of the endless belt 10 is V, and the viscosity coefficient of the resin B is μ, the pressure in the flow path is expressed by the following equation. Here, μ = 1/98 [kgfs / m 2 ] V = 0.5 [m / s] L = 0.5 [m] Ha = 0.001 [m] Hb = 0.03 [m] And the pressure distribution in the flow path, as shown in FIG.
The pressure P in the vicinity of 0.128 [m] is the smallest, and the pressure becomes negative throughout the entire flow path.

止することができる。As described above, according to the liquid impregnating apparatus of the present embodiment, the endless belt 10 and the guide plate 13 which face each other via the fiber A sent in a certain direction are provided. The pressure of the resin B between the endless belt 10 and the guide plate 13 is made lower than the atmospheric pressure by forming the interval 13 so that the upstream side of the upper surface of the endless belt 10 in the moving direction is small and the downstream side is large. Therefore, air can be reliably removed from the resin B impregnated in the fiber A, and a decrease in the strength of the FRP after curing of the resin can be reliably prevented. Further, according to the above configuration, the resin B can be impregnated while the fiber A is fed in the horizontal direction, so that the resin impregnation step can be performed continuously with other steps, and the productivity is significantly improved. Can be. Further, unlike the conventional example, there is no need to bend the fiber A, and the breakage of the fiber A can be reliably prevented.

The section from the guide pulley 43 to the pulley 42 is located slightly above the wheel 41 and has an upward slope. As a result, the interval between the endless belts 30 and 40 is smaller on the upstream side in the moving direction of the facing surface of the endless belts 30 and 40 and larger on the downstream side.
