A method for joining dissimilar materials includes forming a first recess and a second recess by irradiating a surface of a first member with laser light, the first recess and the second recess being cut into the surface obliquely at angles different from each other, and joining the second member to the surface of the first member with a part of the second member engaging with each of the first recess and the second recess by melting the part of the second member lower in melting point than the first member to cause the part of the second member to flow into each of the first recess and the second recess and solidifying the part of the second member.

Tooling, systems, and methods for forming composite parts. The system includes a mold having a first mold portion with a molding surface, a second mold portion with a molding surface, and at least one laminate sheet opening. When the mold is in a closed, molding configuration, the first molding surface and the second molding surface collectively at least partially form an internal cavity defining an outer contour of the composite part. The system also comprises an injection molding nozzle that injects resin into the internal cavity and a laminate sheet supporting frame. The laminate sheet supporting frame supports at least one laminate sheet such that a portion of the at least one laminate sheet is permitted to pass through the at least one laminate sheet opening and conform to at least one of the first molding surface and the second molding surface during the forming of the composite part.

A structure includes: a first member made of metal having a tubular shape, and having a through-insertion hole; a second member made of resin and joined to the first member; and a third member made of metal having a tubular shape, and inserted through inside the first member. The third member is tube-expanded toward the first member and joined to the first member by press-fitting.

To reduce concern of separation due to a user's unintended application of a load.

A joined body of a first structure member having a frame-like structure and a second structure member joined to an inside of the first structure member, wherein the first structure member has a protruding portion in which an anchor shape is formed, the second structure member has a hole portion that comes into contact with the protruding portion of the first structure member, and the protruding portion has a stress concentration portion on which stress concentrates when a load is applied to the second structure member.

A board includes fibers and thermoplastic resin and has a first surface and a second surface that is opposite from the first surface. The board includes a flat body member having edges, a bent portion, a hole, and a filling portion that is made of thermoplastic resin and in the hole. The bent portion extends from one of the edges of the flat body member and includes an edge of the board. The bent portion includes an angled portion that extends along the one of the edges of the flat body member and the bent portion extends from the angled portion at an inclination angle with respect to the flat body member such that the first surface of the angled portion is stretched. The hole is in the first surface of the angled portion.

The invention relates to a hybrid structure comprising a first component having a base and an upstanding wall extending from the base, the first component having an interior enclosed between the upstanding wall and the base, and a thermoplastic second component moulded to the first component, the second component comprising a reinforcing portion for structurally reinforcing the first component, the reinforcing portion extending in a longitudinal direction of the first component and located in the interior of the first component, the thermoplastic second component further comprising a locking portion that extends adjacently over at least part of an exterior of the first component, wherein the reinforcing portion and the locking portion are integrally formed, thus interlocking the first component in the thermoplastic second component. The invention relates as well to a method for manufacturing such a hybrid structure, and to a vehicle comprising such a hybrid structure.

The present disclosure provides for an under-support, which includes curved end portions and a support portion extending between the curved end portion. The support portion includes a plurality of openings. The present disclosure further provides for the under-support embedded in a foam cup. When the disclosed under-support is embedded in a foam cup, the foam extends through the openings in the support portion.

A golf club head includes a club face and a body. The club face is formed from a metallic material and includes a first, hitting surface, a second, rear surface that is opposite the first surface, and a flange that is separated from the second surface by a transverse distance. The body is formed from a polymeric material and includes a crown, a sole, a hosel, and a face support. The club face and the body cooperate to define a closed volume, and the face support extends to opposing sides of the flange and is operative to couple the club face to the body.

The present invention discloses a solenoid valve for water capable of enhancing a electromagnetic suction force and an implementation method thereof. the method comprises: obtaining a plastic-sealed stator assembly by injecting plastic on a stator assembly, the plastic-sealed stator assembly; assembling the plastic-sealed stator assembly and a valve body assembly comprising a movable iron core together to form the solenoid valve for water; wherein the upper end face of the movable iron core at the initial position is set as not lower than the upper edge of lower magnetic conductive inner sleeve and not higher than ¼ of the distance from the upper edge of lower magnetic conductive inner sleeve to the lower edge of upper magnetic conductive inner sleeve, so as to enhance the electromagnetic suction force of the solenoid valve for water. The plastic-sealed stator assembly comprises a coil assembly; an upper magnetic conductive inner sleeve and a lower magnetic conductive inner sleeve mounted in a hole of the coil assembly; a water-isolating sleeve located inside the upper magnetic conductive inner sleeve and the lower magnetic conductive inner sleeve; a yoke located outside the coil assembly and connecting the upper magnetic conductive inner sleeves and the lower magnetic conductive inner sleeves; a magnetic conductive seat mounted on an inner side of the water-isolating sleeve; and a plastic-sealed layer covering the coil assembly and the yoke.

A composite material bush may include a center plate; and an outer foam which is arranged outside the center plate to surround the center plate and is made of different kinds of materials.
