摘要： It is intended to provide a method and an apparatus for manufacturing a fiber-reinforced base material, which is capable of manufacturing a fiber-reinforced base material of high quality while preventing generation of defects such as wrinkles during stacking of the base material sheet. The method for manufacturing the fiber-reinforced base material formed by stacking a base material sheet 5 including a reinforcement fiber 6 onto a mold 2 having a double-curved surface shape, includes steps of: supplying the base material sheet 5 onto the mold 2 from a base material roll 10 while applying distribution varying in a width direction (X direction) to a length of the base material sheet 5 in a sheet-supplying direction of the base material sheet (Y direction) in correspondence with the double-curved surface shape of the mold 2; and applying pressure to the base material sheet 5 in contact with the mold 2.

摘要： A reinforced fiber base material 2 is placed on a forming die 1 having a concave part 10, and the reinforced fiber base material 2 is fixed to the forming die 1 by at least a pair of fixing members 4 disposed on either side of the concave part 10. In doing so, the reinforced fiber base material 2 is fixed to the forming die 1 by the fixing members 4 in a state where a gap is provided between the reinforced fiber base material 2 and a bottom surface 12 of the concave part 10 of the forming die 1. Subsequently, the reinforced fiber base material 2 fixed to the forming die 1 is covered by a bag film 20, a forming space that is formed between the forming die 1 and the bag film 20 is decompressed, and a matrix resin is allowed to flow inside the decompressed forming space. The matrix resin is then hardened so as to obtain a composite material 28 in which the reinforced fiber base material 2 and the matrix resin are integrally formed.
