Title:
繊維強化樹脂シートおよびその製造方法、繊維強化樹脂シートの積層体、並びに繊維強化樹脂成形品の製造方法
Document Type and Number:
Japanese Patent JP7121837
Kind Code:
B2
Abstract:
A fiber-reinforced resin molded article is produced by pressing a plurality of thermoplastic base material sheets, each of which contains a plurality of reinforcing fibers, in a stacked state where the base material sheets are stacked so that the fiber directions (orientation direction of the reinforcing fibers) are alternated. Each base material sheet is provided with a cut including: a plurality of lengthwise cut lines that extend along a plurality of lengthwise reference lines which are parallel to the fiber direction; and a plurality of crosswise cut lines that extend along a plurality of crosswise reference lines which are parallel to a direction that is perpendicular to the fiber direction. A plurality of cut interruption parts for interrupting the lengthwise cut lines in the fiber direction are formed on the lengthwise reference lines. The cut interruption parts are arranged so that cut interruption parts on a first lengthwise reference line and cut interruption parts on a second lengthwise reference line are displaced from each other in the fiber direction.
