  • Preform figuring method, composite material shaping method, composite material, and aircraft structural part
    Patent number: 11453181
    Abstract: A preform figuring method includes mounting and stacking sheet-shape fibrous preparations that have been or are yet to be impregnated with a thermosetting resin on a figuring die that has first and second figuring surfaces at least either one of which is a curved surface and making a preform for a composite material which has a curved surface that corresponds to the curved surface of the figuring die as a stack of the fibrous preparations which has layers by bending the fibrous preparations mounted on the first figuring surface onto the second figuring surface. At least a fraction of the layers that constitute the stack are formed by mounting sheet-shape fibrous preparations on the first figuring surface or the fibrous preparation adjacent in a stacking direction so that the fibrous preparations partly overlap and bending portions of the fibrous preparations mounted so as to overlap onto the second figuring surface.
