A fiber-reinforced composite material and a method for manufacturing the same. A first binder resin is applied to a first portion for forming a deformed part of a fiber base material, and a second binder resin is applied to a second portion excluding the first portion. The fiber base material is then heated so that the degree of melting of the first binder resin during shaping is less than the degree of melting of the second binder resin, and the second binder resin is softened. Shaping is then performed so that a deformed part is formed in the fiber base material, and a preform is obtained. A fiber-reinforced composite material is obtained using the preform as a molding precursor.

Fiber-reinforced composite material and method for manufacturing same

An injection rate (cm/sec) of a screw feeder at the time of starting an injection is the largest and the injection rate (cm/sec) thereof gradually or sequentially decreases until an end of injection so that a temperature of a melted resin reaching the end portion of a cavity decreases within a range where the melted resin is not solidified.
