Method for producing fiber composite
The object of the present invention is to provide a method for producing a fiber composite excellent in lightweight and rigidity. The present method is one for producing fiber composite having a structure in which reinforcing fibers are bonded with a thermoplastic resin, is characterized in that said reinforcing fiber is at least one of a plant fiber and an inorganic fiber, and comprises a feeding process in which a thermally expandable capsule (20) having a shell wall composed of a thermoplastic resin is fed to one of either front side or back side of a mat (10a) comprising the reinforcing fiber and a thermoplastic resin fiber, a dispersing process in which one side of the mat is subjected to vibration from another side of the mat while pressing the one surface side of the mat (10a) to disperse the capsule (20) towards another side of the mat, a melting process in which the thermoplastic resin fiber constituting the mat is molten, and an expanding process in which the capsule (20) dispersed in the mat is heated to expand.
