Abstract
A hybrid molded body according to this embodiment is a hybrid molded body in which a prepreg made of a fiber reinforced plastic and a resin are integrally molded, and the resin includes a covering part that covers at least a part of the prepreg in the boundary part of the prepreg and the resin.
Claims3
A molding method for molding a hybrid molded body by integrally molding a prepreg and a resin in a butted structure, the method comprising:
- press molding the prepreg which is a fiber reinforced plastic sheet, injecting the resin in a sheet form, in such a manner that the resin forms a covering part that covers at least a part of the prepreg in a boundary part of the butted structure between the prepreg and the injected resin, wherein
- a width of the covering part is equal to or larger than an amount of displacement of the prepreg in an xy-plane of the prepreg when arranged in a molding apparatus at a time of the press molding,
- the width and a thickness of the covering part are such that a shear strength in the boundary part of the prepreg and the resin becomes equal to or larger than a shear stress, and
- the covering part is provided over the entire boundary part of the butted structure and is provided only on the boundary part of the butted structure.
