To provide a technique for automatizing a lamination work of a woven prepreg material. A lamination order is decided. A plurality of piece parts 10 is cut out from a prepreg base material. In accordance with the order, the cut-out piece parts 10 are placed on a base sheet 20. The base sheet 20 having the piece parts 10 placed thereon is wound into a roll shape. The base sheet 20 is fed from the feeding reel 31 to be wound by the winding reel 32. A compaction roller 33, in accordance with the order, causes the piece parts 10 to be pressure-bonded against a jig 40 or a laminated body (in the middle of formation) to transfer the piece pats 10 from the base sheet 20. Repetition of the above operations enables lamination of the prepreg materials and achieves formation of a targeted laminated body 50 (final product).
Provided is a technique for automatic lamination of a fabric prepreg material. In the present invention, the sequence of lamination is set. A plurality of fragmented parts 10 are cut out from a prepreg base material. The cut-out fragmented parts 10 are arranged on a belt-shaped base sheet 20 in accordance with the sequence. The base sheet 20 with the fragmented parts 10 arranged thereon is taken up into a roll shape. The roll-shape base sheet 20 is installed on a feed-out reel 31 and a take-up reel 32. The base sheet 20 is fed out from the feed-out reel 31 and taken up on the take-up reel 32. In accordance with the reel operation, the fragmented parts 10 are pressure-bonded, in sequence, to a jig 40 or a laminate (being formed) by a compaction roller 33 and transferred from the base sheet 20. The operations are repeated, the prepreg material is laminated, and an objective laminate 50 (finished product) is formed.
[Problem] To provide technology that can automate the work of laminating a prepreg material, even with respect to complex shapes including curves. [Solution] Compaction rollers 33, 34 are used when compression bonding a prepreg material, in which fibers are impregnated with uncured resin, onto a jig or laminate. The compaction rollers 33, 34 are arranged in parallel with respect to the direction orthogonal to the axes. The compaction rollers 33, 34 are divided in the axial direction. The division position of the compaction roller 33 and the division position of the compaction roller 34 are disposed in a staggered manner.

Provided is a jig stand that can omit a mold release treatment step in a process for molding a fiber-reinforced plastic laminate. A mold release film 40 is bonded to the surface of a jig stand 30. The mold release film 40 is formed by bonding an FEP film 41 and a silicon-based adhesive film 42. It is preferable that the mold release film 40 be thin (100 μm or less). The mold release film 40 is suitable for the jig stand 30 having a free surface. In general, the existing jig stand 30 is made of metal. The thin mold release film 40 is stretchable and can thus be bonded to the free surface of the jig stand 30 while suppressing the occurrence of wrinkles. The thin mold release film 40 does not affect the product shape accuracy. The thickness of the mold release film 40 is uniform as compared to the case of applying a conventional mold releasing agent. In an overall product manufacturing process, mold release treatment and cleaning can be omitted. As a result, the overall product manufacturing process for the fiber-reinforced plastic laminate can be simplified.

VACUUM BAG AND METHOD FOR MANUFACTURING VACUUM BAG
Provided is a vacuum bag which is lightweight, has excellent workability, and can be easily manufactured and reused. This vacuum bag 10 is composed of a diaphragm 11, a frame 12, and a seal 13. The frame 12 is composed of a fiber-reinforced plastic laminate structure 20. The fiber-reinforced plastic laminate structure 20 is covered with a non-silicon-based thermosetting synthetic rubber 26. The curing temperature region of the synthetic rubber 26 and the curing temperature region of the thermosetting resin of the laminate structure 20 overlap each other. Consequently, the synthetic rubber 26 and the laminate structure 20 are molded in one body. In the same step, the synthetic rubber 16 is adhered to the silicon-based diaphragm 11. That is, the vacuum bag 10 is easily manufactured by one-body molding. In particular, when a jig base 30 has a free surface, the effect of easy manufacture becomes remarkable.
