Abstract
The fiber-reinforced resin material of the present invention is a fiber-reinforced resin material having a laminated structure in which fiber assembly layers and thermoplastic resin layers are alternately located, wherein the fiber assembly layers are each an assembly of continuous fibers having thermoplastic resin particles attached to surfaces thereof, and the fiber-reinforced resin material has a higher elongation on one surface side than that on the other surface side. The fiber-reinforced resin structure is made of the present fiber-reinforced resin material. A method for manufacturing the present fiber-reinforced resin material includes: a stacking step of stacking a sheet-shaped product of the continuous fibers that serves as the fiber assembly layer and a resin sheet that serves as the thermoplastic resin layer so as to obtain the laminated structure; and a hot-pressing step of heating and compressing a stacked product obtained through the stacking step in a stacking direction.
