Patent ID: 8173238

Claim:
A molded composite article comprising a plate member and a resin member and having a bonding interface at which the plate member and the resin member are bonded to each other at side end faces thereof facing each other, in which the plate member comprises surface layer base materials positioned on an upper surface side and a lower surface side of the plate member and a core layer base material positioned between the surface layer base materials; and the respective surface layer base materials are each formed of a fiber-reinforced resin, while the core layer base material is formed of a material that is softer than the fiber-reinforced resin forming the respective surface layer base materials, wherein at least a partial bonding interface of the bonding interface is an undulating bonding interface at which undulating side end faces of the respective surface layer base materials and an undulating side end face of the resin member are bonded to each other; a length of an actual bonding line formed along an undulation of the undulating bonding interface is 1.05 mm or more per 1 mm length of a projection-connecting line consisting of straight line segments connecting crests of the respective projections adjacent to each other in an undulation form of the respective surface layer base materials; and at the undulating bonding interface, the resin member has a resin member penetrating tip portion that penetrates into a region between both of the surface layer base materials; wherein the plate member and the resin member are bonded integrally to each other at the bonding interface such that undulating side end faces of the respective surface layer base materials and an undulating side end face of the resin member are integrally bonded to each other.
