A sheet for a fiber-reinforced resin according to the present invention includes a conjugate fiber yarn that contains a low melting point polymer component of a thermoplastic synthetic resin and a high melting point polymer component of a thermoplastic synthetic resin. The low melting point polymer component and the high melting point polymer component are polymers of the same type. When the sheet is formed into a fiber-reinforced resin molded article, the low melting point polymer component serves as a matrix resin, while the high melting point polymer component serves as a reinforcing fiber. The sheet is arranged in at least one direction to form a monolayer or a multilayer. A.fiber-reinforced resin molded article according to the present invention is obtained by heating the sheet for a fiber-reinforced resin according to the present invention to a temperature equal to or higher than the melting point of the low melting point polymer component and lower than the melting point of the high melting point polymer component, followed by compression molding. The present invention can provide a sheet for a fiber-reinforced resin that allows the fiber-reinforced resin to be composed of a thermoplastic synthetic resin, provides good adhesion between a reinforcing fiber and a matrix resin, can include a higher proportion of the reinforcing fiber, and has excellent physical properties such as strength, and a fiber-reinforced resin molded article using the same. |
