Definitions
- the fiber sheet is preferably in a dry state.
- the layers of the laminate are in a slippery state. For this reason, since it can be set as the structure which is easy to accept
- the composite material of the present invention in a three-dimensional orthogonal coordinate system, the composite material whose shape changes in the X direction, the Y direction, and the Z direction, a first inclined surface that is inclined at a first inclination angle with respect to the reference surface;
- the surface on the opposite side of the first inclined surface has a second inclined surface having a second inclined angle smaller than the first inclined angle.
- the fiber content of the inclined part which is a part where the first inclined surface is formed, is smaller than the fiber content of the adjacent part which is a part adjacent to the inclined part.
- the laminate 3 is folded three-dimensionally. Is shaped. Specifically, the laminate 3 is bent two-dimensionally by being bent in the X direction or the Y direction so as to have the same cross-sectional shape in the Z direction. For example, in the case of the spar 10 shown in FIG. 1, the stacked body 3 is bent perpendicular to the Y direction with respect to the XZ plane, and further bent perpendicular to the Y direction with respect to the YZ plane. Moreover, if it is the stringer 20 shown in FIG.
- the laminated body 3 will be bend
- the molding method of this composite material is a molding method using a fiber sheet in a dry state, and VaRTM (Vacuum Assisted Resin Transfer Molding) molding, RTM (Resin Transfer Molding) molding, infusion molding, etc. can be applied. ing.
- VaRTM Vaum Assisted Resin Transfer Molding
- RTM Resin Transfer Molding
- infusion molding etc.
- the stringer 20 shown in FIG. 2 is molded will be described.
- the stringer 20 may be molded integrally with the skin 19 that is the attached member 5, and in the following, the stringer 20 is molded integrally with the skin 19 that is a cured composite material. explain.
- a mold material 30 is installed on the shaped laminate 3.
- the mold member 30 has two divided molds 31a and 31b.
- the skin 19 also functions as a part of the mold 30. That is, the mold member 30 includes two divided molds 31 a and 31 b and the skin 19.
- the two divided molds 31a and 31b are, for example, molds using aluminum.
- the shaped laminate 3 is placed on the skin 19 on which the ply drop-off part 6 is formed, and is pressed so that the two divided molds 31a and 31b are sandwiched from both sides of the laminate 3 above it. It is done.
- the mold 30 has a first inclined molding surface 41 that forms the first inclined surface 21 on the cured stringer 20 to be molded, and a second inclined molding surface 42 that forms the second inclined surface 22.
- the first inclined molding surface 41 is molded so that the inclination angle of the first inclined surface 21 formed on the stringer 20 becomes the first inclination angle ⁇ 1.
- the second inclined molding surface 42 is molded so that the inclination angle of the second inclined surface 22 formed on the stringer 20 becomes a second inclination angle ⁇ 2 smaller than the first inclination angle ⁇ 1.
- the plate thickness at the inclined portion where the first inclined surface 21 is formed is thicker than the plate thickness at adjacent portions adjacent to both sides of the inclined portion. For this reason, the region E1 where the inclined portion is formed is a low Vf region where the fiber content is low, and the region E2 where the adjacent portion is formed is a high Vf region where the fiber content is high.
- the fiber content (Vf: Fiber volume content) is the ratio of carbon fibers contained in the composite material 1.
- the stringer 20 when the stringer 20 is molded using the mold material 30, the stringer 20 is thinned so that the thickness of the stringer 20 after curing is smaller than the thickness of the stringer 20 after shaping (before curing). Is molded.
- excess resin material filled in the laminate 3 is discharged to the outside. At this time, the resin content is discharged to the outside so that the fiber content of the stringer 20 after curing is 20% or less of the fiber content of the stringer 20 after shaping (before curing). Then, the stringer 20 is molded, and more preferably, the stringer 20 is molded so as to have an increment of about 5% to 10%.
- substrate of the composite material 1 after hardening is compared with the plate
- the thickness can be reduced.
- the 1st inclined surfaces 11 and 21 and the 2nd inclined surfaces 12 and 22 of the composite material 1 can be shape
- the mold material 50 is covered with a bagging film 54.
- the bagging film 54 covers the three divided molds 52a, 52b, and 52c, and is provided with a sealing material 53 between the lower mold 51 and hermetically seals the inside. Then, the resin material is filled in the bagging film 54 that is hermetically sealed, and is heated by a heating device (not shown), whereby the resin material is thermoset and the spar 10 is molded.
