A bonded part includes a first surface facing toward a second surface, and a cured adhesive between the first and second surfaces defining a bond line. A surface structure on the first surface is within the bond line and has surface protrusions arranged in a pattern. Each surface protrusion protrudes outwardly from a first end at the first surface to a second end adjacent to the second surface. A thickness of the surface protrusions is substantially equal to the thickness of the bond line. The cured adhesive extends around the surface protrusions. The thickness of the bond line between the first and second surfaces is substantially constant along the bond line, and is greater than a thickness of the cured adhesive between the second ends of the protrusions and the second surface.

Provided is a method for producing a composite member formed by bonding a base material and a resin member. The method includes: a surface treatment step of forming micro-order or nano-order asperities on a surface of a base material; and a bonding step of directly bonding, by injection molding, a resin member to the surface of the base material that has the asperities formed in the surface treatment step. In addition, the composite member includes: a base material having micro-order or nano-order asperities on a surface thereof; and a resin member that is in direct contact with the surface of the base material.

According to one or more embodiments described herein, a laminate glass article may be produced by a method that includes providing a first glass sheet and a second glass sheet, assembling the first glass sheet and second glass sheet into a glass stack, and bonding the first glass sheet to the second glass sheet to form the laminate glass article. In one or more embodiments, an intermediate layer may be positioned between the first bonding surface and the second bonding surface, the first bonding surface and the second bonding surface may be roughened surfaces, or the first bonding surface and the second bonding surface may be chemically treated by vacuum deposition.

Disclosed are a cabin pipeline using a super thermal insulation material and a preparation method thereof, comprising an electrically conductive inner pipe, an anti-corrosion coating coated on the electrically conductive inner pipe, a thermal insulation layer formed by a super thermal insulation material wound on the anti-corrosion coating, and a resin sealing layer coated on an outside of the thermal insulation layer. The electrically conductive inner pipe has excellent corrosion resistance to liquefied natural gas in the pipeline; the protective layer formed by the anti-corrosion coating and the resin sealing layer can prevent the electrically conductive inner pipe from being directly exposed to the environment due to long-term seawater infiltration or accidental damage of the outer layer, avoid electrochemical corrosion and further improve the corrosion resistance.

A base panel suitable to be processed into a covering panel, consisting of the following layers: (i) a substrate having a top surface, (ii) a resilient layer having a top surface and a bottom surface, whereby the bottom surface is connected to the top surface of said substrate, and (iii) optionally, a contact layer between the bottom surface of said resilient layer and the top surface of said substrate. A covering panel further comprising a digitally printed decor on the top surface of the resilient layer of the base panel, and a process of producing covering panels from said base panels.
