| titleOfInvention | Prepreg, fiber-reinforced composite material, and method for manufacturing fiber-reinforced composite material |
| abstract | Provided are: a prepreg that makes it possible to produce a fiber-reinforced composite material in which peeling between layers at a point impact is suppressed; a fiber-reinforced composite material having excellent durability against a point impact; and a method for manufacturing said fiber-reinforced composite material. The projection area of a damaged part of a cured article, obtained by curing a prepreg according to the present invention under a specific curing condition, is 400 mm2 or less, when the projection area is measured by a specific test 1. The maximum value of tanδ of the cured product, when the tanδ is measured by a specific test 2, is observed at 100°C or higher. The prepreg contains a fiber-reinforced base material, an epoxy resin composition, and a polymer (C2), where the polymer (C2) is present on the outermost surface of the prepreg, and the polymer (C2) is observed to have a glass transition temperature of 10°C or lower under a specific measurement condition. A fiber-reinforced composite material production method according to the present invention includes thermoforming of the prepreg according to the present invention. |
