Title:
FIBER-REINFORCED SHEET LAMINATE, PRODUCTION METHOD FOR FIBER-REINFORCED SHEET LAMINATE, AND PRODUCTION METHOD FOR STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2022/145005
Kind Code:
A1
Abstract:
A multi-stack material (1) comprises a plurality of fiber-reinforced sheets (10, 20) that are laminated. The fiber-reinforced sheets (10, 20) include a first fiber-reinforced sheet (10) in which a first fiber (11) extends in a first direction and a second fiber-reinforced sheet (20) in which a second fiber (21) extends in a second direction that is different from the first direction. The first fiber-reinforced sheet (10) has formed therein a plurality of first slits (12) where the first fiber (11) is cut such that each cut-up segment of the first fiber (11) will have an equal length. The second fiber-reinforced sheet (20) has formed therein a plurality of second slits (22) where the second fiber (21) is cut such that each cut-up segment of the second fiber (21) will have an equal length. The first slits (12) and the second slits (22) are arranged so as to overlap with each other when viewed from the direction of lamination.
