    Abstract: Provided are: a molding machine which makes it possible to reduce the misalignment or bending of a fiber bundle; and others. The molding machine is equipped with: a fiber supply device 7 for supplying a fiber bundle 5 to a lamination zone 32 that extends in a first direction; a resin supply device 11 for supplying a resin composition 9 to the lamination zone 32; an impregnation device 17 for impregnating the fiber bundle 5 which is supplied to the lamination zone 32 with the resin composition 9; a curing acceleration device 13 for accelerating the curing of the resin composition 9 which is supplied to the lamination zone 32 while applying a tension to the fiber bundle 5 which is supplied to the lamination zone 32; and a moving device 15 for moving the devices 7, 11, 17 and 13 in the first direction relative to the lamination zone 32. The resin composition 9 comprises (A) an epoxy resin, (B) a cyanate resin and (C) an aromatic amine-type curing agent that has a liquid form at 25°C.

    Abstract: The present invention is a resin composition for a fiber-reinforced plastic, which contains (A) a cyanate ester, (B) an epoxy resin and (C) an aromatic amine-based curing agent that has a liquid form at 25ºC, wherein the average number of cyanate groups in the cyanate ester (A) is 2.1 or more and/or the average number of epoxy groups in the epoxy resin (B) is 2.1 or more. A fiber-reinforced plastic produced using the composition and reinforcing fibers has good heat resistance and excellent tensile and bending properties, and therefore can be applied to wide varieties of fields including transport machines such as ships, automobiles and aircrafts, sports goods, sinks, building materials such as window frames, high-pressure gas tanks, and industrial machineries such as blades for wind power generation.
