Abstract
According to one implementation, a composite material forming jig includes molds and a tilting structure. The molds are developable for laminating fiber sheets, after or before impregnated with a resin, in a developed state where the molds are developed. At least one mold of the molds is capable of being inclined relatively to another mold of the molds so that the laminated fiber sheets are shaped. The tilting structure is adapted to develop the molds when the fiber sheets are laminated and incline the at least one mold when the laminated fiber sheets are shaped.
Claims7
A composite material forming method comprising:
- setting molds in a developed state, at least one mold of the molds being capable of being inclined relatively to another mold;
- laminating fiber sheets, after impregnated with a resin, on the molds in the developed state;
- shaping the laminated fiber sheets impregnated with the resin, by relatively inclining the at least one mold;
- and
- producing a product or a semi-product made of a composite material consisting of the cured resin reinforced with fibers included in the fiber sheets, by thermal curing of the shaped fiber sheets, impregnated with the resin, under a pressure, wherein
- at least one gap between the molds is made narrower as a temporary number of the fiber sheets being laminated increases so that a length in a mountain side of the laminated fiber sheets bent by inclining the at least one mold becomes longer than a length in a valley side of the bent laminated fiber sheets, and
- the at least one mold is relatively inclined by rotating the at least one mold around a rotating shaft by a tilting structure, the tilting structure having the rotating shaft and a part rotating around the rotating shaft, the tilting structure being attachable to and detachable from the at least one mold, the tilting structure being attached to the at least one mold after the at least one gap has been narrowed.
