A method for forming a short fiber product is provided, in which a mixture of short fibers and trees is supplied into the rotating cylinder, and the short fiber product is formed in each dehydration mold while performing centrifugal dewatering, and according to this method, The short fibers can be easily and uniformly fed into the dehydration mold using the fluidized mixture, and since the fibers are centrifugally dehydrated at the same time as they are fed, the centrifugal force allows for sufficient dewatering, and at the same time, the short fibers can be laminated densely. It will be possible.

In FIGS. 1 to 3, (1) is a rotating cylinder, which is supported by a plurality of rollers (2) and is rotatable around a horizontal axis (3). An inner cylinder (4) having an uneven shape in the lateral and circumferential directions is housed in the rotating cylinder (1), and the ends of the plurality of recesses (5) of the inner cylinder (4) Through hole (6
), and a dehydration mold (7) is provided outside each through hole (6).
) is installed. The dewatering mold (7) is made of a wire mesh or a perforated plate, and is molded in advance to match the shape of the fiber-reinforced resin product to be obtained. a supply pipe movable on the horizontal axis (3);
8), and the tip of this supply pipe (8) is provided with an injection port (9) that can face the inner cylinder (4), and the base is provided with short fibers (4) and water (Bl). A hopper 01 is provided to store a mixture (AB) with αυ, αυ is a short fiber manufacturing device, and (2) is a dehydration space.

and water (Bl) are supplied to the hopper (7), where they become a mixture (AB). This mixture (AB) is supplied to the inner cylinder (4).
Supplied to K. At this time, as mentioned above, the rotating cylinder (1) is being rotated, so the mixture (AB) supplied into each dehydration mold (7) is centrifugally dehydrated, and the water (6) is
is taken out to the dewatering space (2), and the short fibers (4) are received by the dewatering mold (7). At this time, the short fibers (aluminum oxide) are suddenly pressed into the dehydration mold (7), and in this state, the mixture (AB) is supplied one after another and layered one after another.Finally A high-density short fiber wheel is formed in the dehydration mold (7). This short fiber material (2) is dried with hot air in the dehydration mold (7), and then taken out as shown in Figure 4. The nine short-edged fibers (2) taken out are inserted into a resin mold α◆ as shown in Fig. 115, and the nine resin mold α◆ is sealed by the cover Q. Then, the intangible 0I
From the 19 side, remove the resin liquid θ'I while performing vacuum desorption iQ.
). As a result, the air in the short fiber material 01 is replaced with the resin liquid αη, and then the resin liquid a is cured to obtain a fiber-reinforced resin product.
