Abstract: A polar functional group is added onto a surface of a metallic member (1). A resin member (2) contains an adhesive functional group. The adhesive functional group and the polar functional group attract each other. A method for joining the metallic member (1) and the resin member (2) to each other includes a heating a junction between the metallic member (1) and the resin member (2) while pressing the metallic member (1) and the resin member (2) against each other with first load, maintaining temperature of the junction higher than melting temperature of a resin that structures the resin member (2) while pressing the metallic member (1) and the resin member (2) with each other with second load smaller than the first load, and cooling the junction to temperature lower than the melting temperature while pressing the metallic member and the resin member against each other with third load larger than the second load.

Abstract: A bridge member is installed in an opening of a water jacket, and a probe of a friction stir welding tool, which rotates about an axis parallel to a cylinder axis, is pressed against a central part of an upper surface of the bridge member. The probe is kept pressed against the central part of the upper surface for a predetermined time to cause side surfaces of the bridge member to expand and come into contact with both a cylinder wall and an outer wall. The probe is moved from the central part of the upper surface to the outer wall, or the cylinder wall, while the probe is kept pressed against the upper surface, thereby friction-stir welding the outer wall, or the cylinder wall, with the bridge member to each other, and after that, the probe is removed off the top deck.

Abstract: A strength prediction method for predicting strength of a structure that is additively manufactured using a 3D printer includes, in the additive manufacturing of the structure, predicting strength of a first layer of the structure in view of a first heat input that is applied when forming the first layer and a second heat input that is applied to the first layer when forming a second layer on the first layer.
