An object is to provide a composite pre-bonding treatment method that stabilizes quality of a bonded part. The present disclosure provides a composite pre-bonding treatment method performed when bonding a composite material to a member. The method includes: (S2) attaching an absorber adapted to absorb a contaminant to a surface of a prepreg laminate that is a precursor of the composite material; (S3) covering the prepreg laminate with a packaging material from above the absorber; (S4) vacuuming the packaging material and heating the prepreg laminate at a temperature lower than a curing temperature of a prepreg; (S5) then removing the packaging material; (S6) peeling off the absorber; (S7) attaching, to a surface of the prepreg laminate with the absorber peeled off, a release member that does not transfer silicone or fluorine to a resin, and then (S9) curing the prepreg laminate to mold the composite material; and (S11) peeling off the release member from the composite material before bonding the member.

This apparatus for manufacturing a laminate comprises: a first sheet transporting device for transporting a first sheet; a water supply device for supplying an aqueous medium to the surface of the first sheet coated with a silane coupling agent and/or the surface of a second sheet coated with a silane coupling agent; and a laminating device for attaching the first sheet and the second sheet which have been supplied with the aqueous medium.

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.

One or more implementations of a multi-layer film include a first layer non-continuously bonded to a second pigmented layer. The multi-layer film includes an unexpected appearance differing from the appearance of the pigmented layer. In one or more embodiments, the multi-layer film includes a metallic appearance despite the pigmented layer being devoid of metallic pigment. The multi-layer film also includes areas that are visually distinct from areas of the film with the unexpected appearance. The visually-distinct areas comprise areas in which the first layer non-continuously is in intimate contact with the second pigmented layer. The visually-distinct areas have the appearance of the pigmented layer or another appearance. One or more implementations also include methods of making multi-layer films and bags with an unexpected appearance and visually-distinct areas.

A floor may include a substrate having a top side and a bottom side. A top layer may be provided on the substrate. The top layer may consist of a printed thermoplastic film and a thermoplastic transparent or translucent layer provided on the printed thermoplastic film. The top layer may be directly adhered to the substrate by heat welding the printed thermoplastic film and the top side of the substrate, in the absence of a glue layer. The substrate may be a synthetic material board including a filler. The substrate at least at two opposite edges may include coupling means provided in the synthetic material board. The thermoplastic transparent or translucent layer may be provided with a structure.

A method may be provided for manufacturing a floor panel having a substrate and a top layer. The top layer may have a decorative layer that includes a digital print and a transparent or translucent wear layer. The method may involve providing the substrate with the digital print by jetting one or more inks from a set of inks using a digital inkjet printer. The ink may include a binding agent that is present in an amount below 20 percent by weight of the ink. The translucent or transparent wear layer may be laminated on top of the digital print.

Compositions-of-matter comprising a matrix made of one or more, preferably two or more elastic layers and one or more viscoelastic layer are disclosed. The compositions-of-matter are characterized by high water-impermeability and optionally by self-recovery. Processes of preparing the compositions-of-matter and uses thereof as tissue substitutes or for repairing damaged tissues are also disclosed.

A flexible film fluid-dispensing device including (A) at least one flexible film liner member having a flexibility property of from 3.6e-10 Nm to 2 Nm; (B) a rigid frame member for receiving the flexible film liner member and for removably holding the flexible film liner member in place during the flow of fluid through the flexible fluid-dispensing device; and (C) a connection means for connecting the flexible film fluid-dispensing device to the outlet feed stream of a fluid production process line; a process of manufacturing the above flexible film fluid-dispensing device; and a process for dispensing a fluid using the above flexible film fluid-dispensing device.

A problem to be solved by the invention is to provide a stretchable laminate achieving both of excellent elongation and an excellent breaking strength, and a method of manufacturing the laminate. A stretchable laminate of the present invention includes non-woven fabric layers and an elastomer layer. The non-woven fabric layers are each a long-fiber hydroentangled non-woven fabric. The stretchable laminate achieving both of excellent elongation and an excellent breaking strength is obtained by using the long-fiber hydroentangled non-woven fabric, which is a non-woven fabric formed through the fixation of fibers formed by a spun-laid method by a hydroentangling method.

This disclosure is directed to methods directly adhering epoxy-based, and other thermosetting surfacing films to solid thermoplastic surfaces and the structures derived or derivable from these methods. In some embodiments, the disclosure is also directed to composite structures comprising a thermoplastic substrate directly bonded to a thermoset(ting) surfacing film; wherein the direct bonding defines an interface between a thermoplastic surface of the thermoplastic substrate and a first surface of the thermoset(ting) surfacing film.
