Method for the production of a laminated core

The invention relates to a method for the production of a laminated core comprising a stack of metallic plates, in which: —a metallic sheet (2, 3) is chosen, having a first main face (4, 8) and a second main face (6, 9) which are coated with a sub-layer comprising at least one material selected from epoxides and polyepoxides, —a layer (12, 20) with a thickness of less than 500 μm of a precursor composition selected from partly epoxides and at least partly cross-linked polyepoxides is placed in contact with said sub-layer, —a layer (16, 22) with a thickness of less than 500 μm of a curing composition comprising at least one crosslinking agent is placed in contact with said sub-layer, —said metallic sheet is punched, —the metallic plates are then superposed to each other.

Self-healing barrier films for vacuum insulation panels

A self-healing vacuum insulation panel and a method of manufacture are provided. The vacuum insulation panel includes a self-healing, multi-layer barrier film including a separator between a curing agent and a curable resin. Upon damage to the separator, the curing agent penetrates the separator due to a pressure differential across the barrier film and reacts with the curable resin to seal any cuts or punctures. The curing agent and the curable resin can be selected to have long term stability and a short reaction time with no need for external stimuli. As a result, the multi-layer barrier film can retain the internal vacuum and maintain a desirably low thermal conductivity using low-cost, commercially available epoxies and curing agents.

FIRE-RATED STRUCTURAL OSB PANELS WITH OVERLAID WATER-RESISTANT BARRIER
20220098859 · 2022-03-31 ·

A wood or engineered wood structural panel, such as, but not limited to, OSB (“oriented strand board”) or plywood, that is both fire-resistant and water resistant. The panel is factory-coated with a product that provides fire resistance. The treatment gives it a Fire-Resistant (FR) performance (for use in a one- or two-hour rated assembly). The panel also is overlaid or coated in a factory setting with a weather/water resistive barrier (WRB). The structural panel thus combines a fire-resistant structural sheathing and WRB product in one integrated panel produced at a factory prior for installation at a job site.

20210331458 · 2021-10-28 ·

A method of preparing antimicrobial material sheets suitable for manufacturing a wide range of products having antimicrobial properties. In exemplary embodiments, a fabric having antimicrobial agents may be calendered with a polymer such as a silicone compound or an elastomer, in order to create a fused material sheet that contains the antibacterial properties of the fabric. In exemplary embodiments, the antimicrobial agent is copper, a copper alloy, silver, a silver alloy, or other suitable antimicrobial agent from which a fabric may be created. In some exemplary embodiments, an uncured silicone composition and copper alloy fabric are calendered to obtain an antimicrobial material sheet suitable for compression molding a wide range of products. In some exemplary embodiments, an uncured silicone composition and copper alloy fabric are calendered and roto-cured to obtain a cured antimicrobial material sheet or sheet rolls that maybe suitable for die-cutting.

A method is provided for managing the temperature of heat sensitive material located near a repair patch being thermally cured on a composite skin using a heating blanket. The method comprises configuring an assembly of thermally conductive cooling blocks to fit within a space between the heating blanket and the heat sensitive material. The assembly of thermally conductive cooling blocks is then installed against the skin within the space, forming a heat sink that conducts a portion of heat out of the composite skin away from the heat sensitive material.

Multi-layer metallic structure and composite-to-metal joint methods

A composite structure comprises stacked sets of laminated fiber reinforced resin plies and metal sheets. Edges of the resin plies and metal sheets are interleaved to form a composite-to-metal joint connecting the resin plies with the metal sheets.

REACTIVATION OF CO-CURED FILM LAYERS

The present disclosure is directed to a method for reactivating a co-cured film layer disposed on a composite structure, the method comprising applying a reactivation treatment composition comprising at least two solvents and a surface exchange agent comprising a metal alkoxide or chelate thereof to the co-cured film layer, and allowing the reactivation treatment composition to create a reactivated co-cured film layer, wherein the co-cured film layer was previously cured at a curing temperature greater than about 50° C. A reactivated co-cured film layer and an aircraft part having a reactivated co-cured film layer are also provided.

ANTIMICROBIAL ASSEMBLIES

According to various examples of the present disclosure, an antimicrobial assembly includes a substrate comprising a matrix material having opposed first and second surfaces with a total thickness of the substrate defined therebetween. The assembly further includes an antimicrobial composition bound to the substrate and heterogeneously distributed about the antimicrobial assembly.
