Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1 . 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. 2 . The molding method for molding the hybrid molded body according to claim 1 , wherein the shear stress is obtained by dividing a shear force that is generated by applying a tensile strength in an x-axis direction to the hybrid molded body by an area of the boundary part of the prepreg and the covering part, and the shear strength in the boundary part of the prepreg and the resin depends on a strength that materials of the prepreg and the resin have and the width and the thickness of the covering part. 3 . The molding method for molding the hybrid molded body according to claim 1 , wherein the butted structure includes a bonding surface between the prepreg and the resin in a zy plane of the prepreg when arranged in the molding apparatus at the time of the press molding, and the covering part covers at least a part of the xy plane of the bonding surface on a z-axis positive side.
