A method of bonding a second object to a first object includes: providing the first object having a thermoplastic liquefiable material in a solid state; providing the second object having a surface portion that has a coupling structure with an undercut, so that the second object is capable of making a positive-fit connection with the first object; pressing the second object against the first object with a tool that is in physical contact with a coupling-in structure of the second object while mechanical vibrations are coupled into the tool; continuing to press and couple vibrations into the tool until a flow portion of the thermoplastic material of the first object is liquefied and flows into the coupling structures of the second object; and letting the thermoplastic material re-solidify to yield a positive-fit connection between the first and second objects by the re-solidified flow portion interpenetrating the coupling structures.

A connection including a first profile having a first end and a first lumen, the first profile including a first polymeric material and a second profile having a second end and a second lumen, the second profile including a second polymeric material, a metal, or combination thereof, wherein the first end and the second end are coincidently welded via an ionized gas treatment.

A connection includes: a first profile having a first end, the first profile including a first polymeric material comprising a thermoset material; and a second profile having a second end, the second profile including a second polymeric material, a metal, or combination thereof, wherein the first end and the second end are coincidently bonded without a bonding material at an interface of the first end and the second end.

A method of directly joining a polymer to a metal along a joint interface through the formation of CO-M chemical bonds, where M represents an element in the metal to be joined. The method includes heating the metal to a predetermined temperature above a glass transition temperature of the polymer and less than a flash ignition temperature of the polymer and less than a metal melting temperature of the metal; physically contacting at least one of the metal and the polymer; and applying compression pressure to the joint interface of the metal and the polymer when the metal is above the glass transition temperature of the polymer and less than the flash ignition temperature of the polymer and less than the metal melting temperature of the metal to generate intimate atomic contact between the metal and the polymer to create CO-M chemical bonds between the metal and the polymer.

Methods of bonding a first object to a second object, including the steps of: providing the second object having a protrusion; providing the first object having a thermoplastic material; positioning the first object relative to the second object such that an assembly of the first and the second object is formed; applying a relative force between the second and first objects and applying mechanical vibration to the assembly of the first and the second object until at least a flow portion of the thermoplastic material becomes flowable and flows around the protrusion; and causing the thermoplastic material to re-solidify. The first object may be a connecting element including a feedthrough, wherein the second object has a corresponding opening. The protrusion may be deformed such that the protrusion has an undercut relative to an axis along which the first and second objects are pressed against each other.

Disclosed are an integrated structure of different kinds of materials formed by integrating a steel material and a fiber reinforced composite material, and a method of integrating different kinds materials. An integrated structure of different kinds of materials may be formed by integrating different kinds of materials that are a steel material and a fiber reinforced composite material. The integrated structure includes: a first plate including a steel material; and a second plate facing the first plate and including a fiber reinforced composite material, which may be formed by impregnating resin in a reinforced fiber. In particular, a thermal bonding layer may be formed at an interface of the first plate and the second plate and include the resin of the second plate which is thermally bonded on a surface of the first plate.

A method of bonding a second object to a first object includes: providing the first object having a thermoplastic liquefiable material in a solid state; providing the second object having a surface portion that has a coupling structure with an undercut, so that the second object is capable of making a positive-fit connection with the first object; pressing the second object against the first object with a tool that is in physical contact with a coupling-in structure of the second object while mechanical vibrations are coupled into the tool; continuing to press and couple vibrations into the tool until a flow portion of the thermoplastic material of the first object is liquefied and flows into the coupling structures of the second object; and letting the thermoplastic material re-solidify to yield a positive-fit connection between the first and second objects by the re-solidified flow portion interpenetrating the coupling structures.

[Problem]

To provide a metal/fiber-reinforced resin material composite in which a metal member and a fiber-reinforced resin material are firmly bonded, a light weight and excellent workability are obtained while the strength is enhanced, and the amount of the fiber-reinforced resin material used can be reduced.

[Solution]

A metal/fiber-reinforced resin material composite comprising a metal member, and a first fiber-reinforced resin material having a matrix resin and a reinforcement fiber material, the metal member and the first fiber-reinforced resin material being formed into a composite with an adhesive resin layer interposed therebetween, wherein the adhesive resin layer is obtained by solidifying or curing an adhesive resin composition containing at least 50 mass parts of a phenoxy resin (A), and the maximum load of the metal/fiber-reinforced resin material composite is greater than the total load of the maximum load of the metal member alone and the maximum load of the fiber-reinforced resin material alone (i.e., so as to display a super-law-of-mixture (or law of over-mixture) that surpasses the law of mixture with respect to the tensile load).

Channel joints (1) can permit bonding a tube or tubular member (30) to an end fitting (20) in double shear. The channel joint may include a receiving channel (25) in the end fitting (20) that is complementary in shape to the tube, tubular member, or other hollow member (30) that is to be fitted and bonded with the end fitting. The use of a channel joint allows for simplified assembly because the receiving channel acts as a reservoir for the bonding agent or adhesive (50). Upon insertion of the tube, tubular member, or other hollow member into the adhesive-loaded receiving channel, the adhesive will backflow to fill the voids in the joint and expel the excess adhesive.
