Definitions
- the present invention relates to an FRP molding jig used for molding an FRP (fiber reinforced plastic) structure and a method for molding the FRP structure.
- a main structural material such as an outer plate and a reinforcing part such as a stringer are joined and combined.
- the positioning accuracy between the main structural member and the reinforcing component becomes a problem.
- the method of pressing the main structural material and the reinforcing component, the arrangement of the jig, and the like at the time of joining are problematic.
- FIG. 1 of US Patent Application Publication No. 2011/0315824 discloses a method for forming an FRP structure in which a main structural member and a reinforcing component are joined and combined.
- a groove for positioning a stiffener preform (reinforcing component) is formed in a jig for FRP structure molding, and the stiffener preform is formed in the groove.
- Reinforcing parts is placed and covered with reinforcing fibers (base material of the main structural material).
- a release material and a matrix resin diffusion sheet are arranged, covered with a vacuum bag, the inside of the vacuum bag is evacuated, and the matrix resin is injected. Thereafter, the matrix resin is cured by heating or the like.
- Patent Document 2 describes that a male jig is used when applying a reinforcing material to a composite material structure that is a fuselage of an aircraft.
- Patent Document 3 describes that a jig provided with a support and a plurality of panels is used when a reinforcing material or a stringer is applied to a composite material structure that is a fuselage of an aircraft.
- reinforcing parts are arranged directly in grooves formed in a jig, and positioning is performed with respect to the main structural material.
- this positioning method it is necessary to determine the groove width dimension of the jig in consideration of the shape tolerance on the reinforcing component side. Due to the influence of this tolerance, there is a problem that the positioning accuracy of the reinforcing component with respect to the main structural material is deteriorated.
- co-bonding there is a problem that it is difficult to obtain a positioning accuracy of a cured part with respect to an uncured part.
- FIG. 8 shows a positioning method of the reinforcing component 14 with respect to the conventional main structural material 112.
- the FRP structure has a main structural member 112, a reinforcing component 14, and a joint 16 that joins the main structural member 112 and the reinforcing component 14.
- the main structural material 112 is, for example, a prepreg material that forms an outer panel of an aircraft.
- the reinforcing component 14 is, for example, a stringer and is a prepreg material having a T-shaped cross section.
- the main structure material 112 is disposed on the main structure jig 122 having a predetermined shape.
- the joining portion 16 is disposed, and the vertical extending portion of the reinforcing component 14 is inserted into the U-shaped groove of the positioning jig 126 to position the reinforcing component 14 with respect to the main structural material 112. . Then, the joint 16 is cured in a state where a force pressing the reinforcing component 14 against the main structural member 112 is applied. Thus, the FRP structure is completed.
- the reinforcing component 14 has a shape tolerance and a dimensional tolerance, it is necessary to previously form a gap between the reinforcing component 14 and the engaging portion of the positioning jig 126. Due to the presence of this gap, there is a problem that the positioning accuracy of the reinforcing component 14 with respect to the main structural member 112 is lowered.
- the FRP structure in which a closed space exists between the main structural material and the reinforcing component, or when a part of the structural component interferes with each other when forming integrally, the main structural material is reinforced.
- bagging that presses the parts becomes difficult.
- An object of the present invention is to provide an FRP molding jig and a method for molding an FRP structure, which are capable of molding a main structural material and a reinforcing component integrally with high accuracy.
- the FRP molding jig of the present invention relates to an FRP molding jig used when molding an FRP structure by joining a main structural material and a reinforcing component.
- the FRP forming jig includes a main structural material holding jig and a flexible reinforcing part holding jig.
- the main structural material holding jig positions and holds the main structural material composed of fiber components.
- the reinforcing component holding jig is positioned with respect to the main structural material holding jig and presses and holds the reinforcing component composed of fiber components.
- the FRP structure forming method of the present invention is a method of forming an FRP structure by joining a main structural member and a reinforcing component using an FRP forming jig.
- the FRP forming jig includes a main structural material holding jig and a flexible reinforcing part holding jig.
