- the method for laminating the substrate laminate is not particularly limited, but the layered body ⁇ is preferably laminated between a plurality of layered bodies ⁇ . Since the layered body ⁇ having a lower degree of extension than the layered body ⁇ is on the surface of the substrate laminate, the fiber orientation disorder caused by the large stretching does not appear in the outer layer.
- the orientation of the layered body ⁇ can be made uniform by sandwiching the layered body ⁇ between the layered body ⁇ . Thereby, improvement of mechanical properties such as bending rigidity and good surface quality can be realized.
- a part of the complex shape may be formed by the layered body ⁇ alone by greatly flowing the layered body ⁇ having high fluidity.

- the notch prepreg manufactured by inserting a notch into a continuous fiber prepreg in which reinforcing fibers are oriented in one direction also includes notches adjacent to each other in the fiber direction as shown in FIG. Since the reinforcing fiber bundle can be defined by the quadrilateral region formed by two line segments connecting the two, the reinforcing fiber bundle becomes a base material arranged in one direction over the entire surface of the prepreg.
- the reinforcing fiber bundle of the substrate B is a substrate oriented in five or more directions.
- the orientation direction of the reinforcing fiber bundle is defined by the fiber direction of the reinforcing fibers arranged in one direction constituting the reinforcing fiber bundle.
- the number of orientations of the reinforcing fiber bundle of the base material B is measured by observing the reinforcing fiber bundle on the surface with a microscope after the base material B is solidified as necessary.
- the manufacturing equipment can be simplified and manufactured at a lower cost than manufacturing a sheet in which all the reinforcing fiber bundles are controlled in one direction. More preferably, when the base material B is a base material oriented in eight directions or more, it becomes easier to flow isotropically. More preferably, the reinforcing fiber bundle is uniformly arranged at random. An example of the form of such a substrate is SMC. More preferably, the end portion of the reinforcing fiber bundle is oblique with respect to the fiber direction. By being diagonal, the end portions of the reinforcing fibers are easily crushed during press molding, and a molded product with few resin-rich portions can be produced when a fiber reinforced plastic is used.
- a more preferable form of the substrate laminate is that the fiber length of the reinforcing fibers contained in the substrate B is in the range of 25 to 50 mm and the fiber volume content is 30 to 45%.

It is a cut prepreg B, and the fiber volume content of the cut prepreg B is a base material lower than the fiber volume content of the cut prepreg A. Since the base material B is a cut prepreg, substantially all of the reinforcing fibers constituting the base material B are oriented in one direction, so that the fiber orientation can be controlled. Therefore, by controlling the fiber orientation for each layer together with the cut prepreg A, the mechanical properties of the fiber-reinforced plastic after molding can be arbitrarily set.
- the fiber volume content of the cut prepreg B is preferably lower than that of the cut prepreg A.
- the fiber volume content of the cut prepreg B is preferably 10% or more lower than that of the cut prepreg A.
- the cut of the cut prepreg B there is no particular limitation on the form of the cut of the cut prepreg B.

- the cutting prepreg B may be the same cutting pattern as the cutting prepreg A or a different cutting pattern depending on the purpose, and can be selected according to required characteristics. By setting the same cutting pattern, the cutting pattern of the cutting prepreg B is not transferred to the surface of the fiber-reinforced plastic after molding, and uniform surface quality can be obtained. On the other hand, by changing the cutting pattern, it is possible to change the fluidity of the cutting prepreg B and improve the moldability.
- the layered body ⁇ has one or more base materials B, and the laminated structure is not particularly limited. However, it is preferable that the layered body ⁇ is laminated so that two or more base materials B are laminated and the orientation angles of the reinforcing fibers are different in the respective layers. By being laminated in this manner, when the base material B is the cut prepreg B, the reinforcing fibers in each cut prepreg B also flow in the fiber longitudinal direction. Examples of such lamination forms include pseudo isotropic lamination and orthogonal lamination. When it is desired to give isotropic mechanical properties to the fiber reinforced plastic after molding, pseudo isotropic lamination is suitable, and when more extensibility of the base material during molding is desired, orthogonal lamination is suitable.
- a more preferable form of the substrate laminate is that the fiber length of the reinforcing fibers contained in the substrate B is in the range of 10 to 300 mm, and the fiber volume content is in the range of 45 to 55%. It is done.
- the base material B is a cut prepreg B, the fiber volume content of the cut prepreg B is lower than the fiber volume content of the cut prepreg A, and the fiber length of the reinforcing fibers contained in the base material B Is in the range of 10 to 300 mm, and the fiber volume content of the base material B is in the range of 45 to 55%.
- the fiber length of the reinforcing fiber of the base material B is preferably in the range of 10 to 300 mm from the relationship between fluidity and mechanical properties, as in the case of the cut prepreg A. More preferably, it is 10 to 50 mm.
- the fiber volume content of the substrate B is preferably 45% or more so that the fiber-reinforced plastic can obtain sufficient mechanical properties as a structural material.
- the fiber volume content is higher than that of the base material in which the reinforcing fiber bundle of the base material B is oriented in five or more directions, which is another preferred form, the resin is used when the base material B is the cut prepreg B. Can be unevenly distributed between the layers.
- the fiber volume content of the reinforcing fibers of the base material B is preferably in the range of 45 to 55%.
- the lower limit of the fiber volume content depends on the fiber length.
- the fiber volume content of the reinforcing fibers is preferably 45% or more when the fiber length is 10 mm, but may be 40% or more when the fiber length is 15 mm, for example.
- the number of fibers of the reinforcing fiber bundle constituting the base material B is larger than the number of fibers of the reinforcing fiber bundle constituting the cut prepreg A.
- the reinforcing fiber bundle of the incision prepreg defines the reinforcing fiber bundle by a quadrilateral region composed of incisions adjacent to each other in the fiber direction and two line segments connecting the vertices of the incisions. can do.
