    摘要: A structural member including a lightweight core, one or more skins, and a crosslinking nanolayer interposed therebetween that results in significant mechanical strength in the structure. The core is a polymer of reduced density by way of included voids, such as an open or closed cell foam, honeycomb, or corrugated structure. The core polymer has a lower density and may have a higher softening or melting temperature than the polymer skin materials. The core may be discontinuous at the interface with the skin such that only a small percentage of the core surface is actually in contact with the skin compared to the overall area of the interface. The skin may be a thermoplastic layer that attaches to the core material. The skin may be a composite material including non-thermoplastic reinforcements. The crosslinking nanolayer is covalently bonded to the surface of the core material and provides molecular compatibility with the skin material.

    摘要: The present invention is to provide a method for producing a laminate having excellent adhesion properties. An embodiment of the present invention is a method for producing a laminate, the method including: a step 1 of dry-treating a surface A of a plastic to obtain a dry-treated plastic having a surface B that has been dry-treated; a step 2 of wiping the surface B with a cleaning tool containing a composition for wiping, the composition containing at least one solvent selected from the group consisting of water and polar solvents, and a silane coupling agent, to obtain a cleaned plastic having a surface C that has been wiped with the cleaning tool; and a step 3 of applying at least one selected from the group consisting of adhesives and primers on the surface C to obtain a laminated body.
