A multi-stack material includes a plurality of fiber-reinforced sheets that are laminated. The fiber-reinforced sheets include a first fiber-reinforced sheet in which a first fiber extends in a first direction and a second fiber-reinforced sheet in which a second fiber extends in a second direction that is different from the first direction. The first fiber-reinforced sheet has formed therein a plurality of first slits where the first fiber is cut such that each cut-up segment of the first fiber will have an equal length. The second fiber-reinforced sheet has formed therein a plurality of second slits where the second fiber is cut such that each cut-up segment of the second fiber will have an equal length. The first slits and the second slits are arranged so as to overlap with each other when viewed from the direction of lamination.

Fiber-reinforced sheet laminate, production method for fiber-reinforced sheet laminate, and production method for structure

A method includes laminating a plurality of fiber reinforced sheets to create a charge; and shaping, by pressing, the charge created in the lamination step into a shaping mold. The charge has a predetermined angle layer including the plurality of fiber reinforced sheets, the fiber direction of which is aligned in a single direction. The predetermined angle layer has n-number of constitutional layers (n≥2) ranging from a first constitutional layer to an n-th constitutional layer each including the plurality of fiber reinforced sheets, wherein the n-th constitutional layer is laminated on an (n−1)-th constitutional layer, the plurality of fiber reinforced sheets in each of the constitutional layers have dividing portions which are along the fiber direction and which are disposed one by one at respective positions within a predetermined range along the fiber direction in the predetermined angle layer.

Composite material component shaping method and charge

A fuel tank dam comprises a first section, a second section, a third section, and a flange section. The first section can be fixed to a first structural component, and the second section can be fixed to a second structural component. The third section has a bellows comprising a plurality of folded sections and is disposed between the first section and the second section. The flange section extends along an outer plate at least from an edge section of the third section and can be fixed to the outer plate.
