A composite structure comprising a resinous component that is adhered to a surface of a metal component is provided. The resinous component is formed from a polymer composition that comprises a polyarylene sulfide, inorganic fibers, and an impact modifier. The inorganic fibers have an aspect ratio of from about 1.5 to about 10.

A method for producing a foam-molded product by using a plasticizing cylinder, includes: plasticizing and melting the thermoplastic resin to provide the molten resin in a plasticization zone of the plasticizing cylinder; introducing a pressurized fluid containing the physical foaming agent at a fixed pressure into a starvation zone of the plasticizing cylinder to retain the starvation zone at the fixed pressure; allowing the molten resin to be in the starved state in the starvation zone; bringing the molten resin in contact with the pressurized fluid containing the physical foaming agent at the fixed pressure, in the starvation zone in a state in which the starvation zone is retained at the fixed pressure; and molding the molten resin having been brought in contact with the pressurized fluid containing the physical foaming agent into the foam-molded product.

An aluminum alloy material is prepared that has surface configuration of threefold irregularities such that rough surface having surface roughness of 10 to 100 μm period is observed with an electron microscope in a magnification of 1000 times, surface having fine irregularities of 1 to 5 μm period based on crystal grain boundary is observed with an electron microscope in a magnification of 10000 times and surface having ultrafine irregularities of 30 to 100 nm period is confirmed with an electron microscope in a magnification of 100000 times. Aluminum alloy material is integrally joined with a resin composition consisting of a total resin part containing polyphenylene sulfide resin by 70 mass % or more of the resin part, modified polyolefin resin by 30 mass % or less of the resin part and a resin of third component having ability for promoting compatibility of polyphenylene sulfide resin and modified polyolefin resin.

A first object is anchored in a second object. The first object has a material with thermoplastic properties, and the second material has a material that is solid and is penetrable by the first material when in a liquefied state. The second object has an insertion face with an opening having a mouth in the insertion face, and the first object has an insert portion that for anchoring is placed in the opening or about the mouth thereof. For anchoring, energy suitable for liquefaction of the first material impinges in an amount and for a time sufficient for at least partial liquefaction of the first material and interpenetration of the first and second materials. The second object, around the opening, has an anisotropic strength with respect to forces perpendicular to the opening axis.

A joining element has an anchoring portion for in-depth anchoring in the object and a head portion arranged proximally of the anchoring portion with respect to an insertion axis. The head portion has a lateral outer surface that has a structure that is well-defined, especially within tight tolerances. The joining element is positioned relative to an object of a non-liquefiable material such that the anchoring portion reaches into an opening of the object or is placed adjacent a mouth thereof. Then, the joining element is pressed towards a distal direction, to press the anchoring portion into the opening, while mechanical vibration energy is coupled into the joining element by a tool, in an amount and for a time sufficient for liquefaction of a portion of the thermoplastic material to cause interpenetration of the thermoplastic material into structures of the object.

Display modules typically incorporate a transparent hard material such as glass on the outside of the module in order to better protect the display stack from scratches, dents, and other mechanical deformations. However, as displays move to novel form factors such as bendable, foldable, and reliable display modules, these transparent hard materials (e.g., glass) may not be used due to their limited flexibility. Therefore, it is desirable that replacement materials be sufficiently flexible while maintaining the desirable optical (e.g., >90% transmission and low yellow index) and mechanical properties (e.g., pencil hardness>H) that comparable glass hard materials offer.

Provided is a cladding composition which contains metal powder, a binder, and an organic solvent in a case of bonding a metal base material and a resin member to each other. Further, provided is a method for producing a metal/resin bonded member, including a step of coating at least a portion of a metal base material with the cladding composition; a step of irradiating the coated portion of the metal base material which has been coated with the cladding composition, with a laser; a step of disposing the resin member on the laser irradiation portion of the metal base material; and a step of heating an interface between the laser irradiation portion and the resin member so that the metal base material and the resin member are bonded to each other.
