  • the cutting process for cutting the laminated plate 1 the cutting process that does not penetrate the laminated plate 1, and the excision that trims the side surface of the laminated plate 1. Processing may be sufficient as long as it is a cutting process. That is, in Embodiment 1, although the case where the laminated board 1 was cut from the hard layer 12 side was demonstrated, it may cut from the side surface of the laminated board 1, and is not specifically limited.
  • FIG. 4 is a cross-sectional view illustrating an example of a laminated plate according to the second embodiment.
  • parts that are different from the first embodiment will be described in order to avoid redundant descriptions, and parts that are the same as those in the first embodiment will be described with the same reference numerals.
  • the laminated plate 50 of the second embodiment includes a plurality of difficult-to-cut layers 11 and a plurality of hard layers 12, and the plurality of difficult-to-cut layers 11 are provided between the plurality of hard layers 12.
  • the laminated plate 50 has a structure in which a plurality of difficult-to-cut layers 11 are sandwiched between a plurality of hard layers 12.
  • the plurality of difficult-to-cut layers 11 are provided in a distributed manner by being provided with a plurality (for example, two layers in the second embodiment) with a predetermined interval in the stacking direction.
  • the two difficult-to-cut layers 11 are provided so that the fiber directions of the polyarylate fibers intersect each other. Specifically, based on the blade length direction of the blade body to which the laminated plate 50 is applied, the two hard-to-cut layers 11 have different fiber directions of the polyarylate fibers so as to be ⁇ 45 °. Yes.
  • the fiber direction of the polyarylate fibers in the two difficult-to-cut layers 11 is not limited to the above, and may be ⁇ 60 ° or ⁇ 30 °.
  • the plurality of difficult-to-cut layers 11 are arranged in the stacking direction to suppress an increase in the rigidity difference between the difficult-to-cut layer 11 and the hard layer 12. can do.
  • the isotropic or anisotropic characteristics of the laminated plate 50 can be adjusted by appropriately changing the fiber directions of the plurality of difficult-to-cut layers 11. That is, by adjusting the isotropic or anisotropic characteristics of the laminated plate 1 according to the structure of the wing body, the vibration damping characteristics of the laminated plate 50 may be suitable for the wing body. it can. Therefore, the laminated board 50 can suppress suitably the vibration of a wing body.
