Abstract
The present invention provides a method for manufacturing a random sheet having a better external appearance. This random sheet manufacturing method comprises: a step for spreading, in a planar manner, thin pieces of a fiber-reinforced resin obtained by impregnating a plurality of reinforcing fibers arranged oriented in one direction with a first thermoplastic resin; a step for adding a powder of a second thermoplastic resin to the thin pieces which have been spread; and a step for heating and pressurizing the thin pieces to which the powder has been added and unifying the thin pieces with each other.
Claims6
A method for producing a random sheet, the method comprising:
- spreading thin pieces of a fiber reinforced resin so as to form a flat shape, wherein in the fiber reinforced resin, a plurality of reinforcing fibers arranged to be oriented in one direction are impregnated with a first thermoplastic resin;
- applying powder of a second thermoplastic resin to the thin pieces spread;
- and
- integrating the thin pieces with each other by heating and pressurizing the thin pieces, the thin pieces being subjected to the applying of the powder.
