Since it is preferable for the resin diffusion medium to have a high impregnation coefficient as described above, a sufficient amount of resin can be transferred from the end of the resin diffusion medium to the center by using such a substrate with a high impregnation coefficient. It becomes possible to make it flow toward a part or the edge part on the opposite side. However, if this resin diffusion medium is too thin, it will be difficult to flow a sufficient amount of resin, and if it is too thick, it will be difficult to maintain the desired laminate form as a whole.

- Impregnation coefficient ratio K1 / K2 Kl: The largest value of the impregnation coefficient of the base material in the laminated structure
- the resin impregnation coefficient is a value measured by the following measurement method.
- v (m / s) is the impregnation rate
- K (m 2 ) is the impregnation coefficient
- ⁇ ( ⁇ a) / AL (m) is the pressure gradient per unit length.
- L (m) is the distance to the flow front (the tip of the fluidized resin) of the resin injection port force.
- the impregnation coefficient can also be calculated by knowing the distance to the flow front, the time to reach it, the viscosity of the resin and the molding pressure. Therefore, the impregnation coefficient can be measured by conducting an impregnation coefficient measurement experiment on a basic shape such as a flat plate using an apparatus as shown in Fig. 2 as an example, and measuring the impregnation coefficient K.
- an impregnation coefficient measuring apparatus 11 when measuring the impregnation coefficient, for example, an impregnation coefficient measuring apparatus 11 as shown in FIG. 2 is used.
- the pressure ⁇ is set to lOOkPa by maintaining the pressure inside the device 11 at a gauge pressure higher than the vacuum level of ⁇ lOOkPa.
- the cover factor refers to the ratio of the fiber area per unit area.
- the cover factor is measured by the following procedure. Expand the target substrate with a copy machine, etc., and measure the longitudinal dimension Y and transverse dimension X per 10 fiber bundles. At this time, enlargement with a copier is performed so that the horizontal dimension per 10 fiber bundles is 100 ⁇ 5 mm, and measurement is performed using calipers that can display up to 0.01 mm.
- the width of each of the 10 fiber bundles is 30 for a longitudinal fiber, with a total of 30 fiber bundles at a pitch of XZ2 and 3 for each fiber bundle at a pitch of YZ2. Measure a total of 30 points, and calculate the longitudinal fiber width average value X and the transverse fiber width average value y.
- Cover factor Cf is expressed by the following equation.
- the thickness of the resin diffusion medium used in the present invention is preferably 200 to 2000 ⁇ m from the viewpoint of obtaining a molded article having good appearance. If it is thinner than 200 m, it will prevent the passage of air bubbles inside the resin, and it will be easy to form a void pool near the injection port, and if it is thicker than 2000 m, more voids can accumulate in the layer. As a result, the weight of the molded body increases and the light weight effect is lost.
- a thick resin dispersion medium for example, when a glass fiber mat is used, it is possible to use a 200 to 900 g / m 2 (a plurality of sheets may have a basis weight). realizable. It should be noted that the resin diffusion medium may satisfy the above thickness even if it is composed of only one layer or a plurality of layers in the molded body.
- the resin flows mainly into the resin diffusion medium layer, and bubbles in the resin that adversely affect the appearance are removed from the resin diffusion medium layer. Since it becomes easy to stay inside, it becomes possible to obtain a molded article having a good appearance. From this point of view, the upper limit is preferably as long as the coefficient is large, but the above-mentioned ranges are listed as currently available. Further, when a material having a larger impregnation coefficient becomes available, it can be preferably applied. [0034] Furthermore, the form of the material used for the resin diffusion medium may be a mesh, a woven fabric, or a nonwoven fabric as described above. For example, when a nonwoven fabric such as a glass fiber chopped mat or a continuous strand mat is used, Low cost molded bodies can be obtained, and voids are easily stored in the layer.
- the resin diffusion medium may be a combination of an extended form at each end, which may be extended at both ends, or a form having a different relationship with the adjacent layer.
- L1 and L2 indicate the protruding length of the resin diffusion medium 21, and it is only necessary to extend outward from at least one adjacent layer.
- the protruding length is preferably 1 mm or more, and preferably in the range of lmm to 30 mm.
- the thickness is between the resin diffusion medium 32. It is preferable to provide a 50-2000 m slag fluid base material 33.
- the resin fluid base material 33 need not be disposed over the entire surface of the core material 31 as long as it is disposed only at the end of the core material 31.
- the groove 36 is machined on at least one side of the core material 33. Is also preferable. Due to the presence of the core groove 36, the diffusion resin by the resin diffusion medium 32 is diffused more quickly and uniformly.
- the bubble component present in the resin is mainly passed through the resin diffusion medium layer, and the bubbles are formed by the specific intermediate layer. Since it is difficult to reach the surface of the body, it is possible to obtain a molded product of fiber reinforced resin that has excellent surface quality and has almost no pinholes in appearance while reducing the need for post-processing such as repair. .
- the fiber reinforced resin obtained as described above is a carbon fiber reinforced plastic (CF) that is lightweight, high-strength, highly elastic, and excellent in impact resistance by using carbon fiber as the reinforcing fiber.
- CF carbon fiber reinforced plastic
- RP carbon fiber reinforced plastic
- the CFRP member is made of a reinforcing fiber other than carbon fiber (for example, glass fiber, aramid fiber, PBO (polypropylene-ethylene benzoate) as long as it does not impair the light weight, high strength, high elasticity, and impact resistance.
- CFRP members are preferably used as automotive parts that require mass production with a particularly short molding cycle.
