Methods for combining components of varying stages of cure

The present disclosure relates to a method of fabricating a composite structure using a pre-cured composite stiffener and a dry fabric component. In one example, the method includes the steps of: wrapping an adhesive film and a resin film around an edge of said pre-cured composite stiffener; inserting the edge of said pre-cured composite stiffener into a clevis of a dry fabric component to form a composite structure assembly; securing the pre-cured composite stiffener substantially perpendicularly to the base portion of the dry fabric component; and starting a consolidated infusion and cure process. The consolidated infusion and cure process applies a first temperature to the composite structure assembly for a first predetermined period of time to infuse the dry fabric component, and the increases the first temperature to a second temperature for a second predetermined period of time to cure the composite structure assembly.

PREPARATION METHOD OF SOLAR CELL BACKSHEET FILM WITH HIGH REFLECTIVITY
20200313014 · 2020-10-01 ·

The disclosure discloses a method for preparing a high-reflection solar cell backsheet film, which uses a twin-screw extruder to prepare a masterbatch of an adhesive layer, a masterbatch of a barrier layer, and a masterbatch of a high-reflection layer, and then uses four single-screw extruders to melt the three masterbatches at 250 C. and extrude through a lip film of a casting head. A non-woven fabric is added as a base layer between the two barrier layers, so that the two barrier layers are extruded through the lip film and integrally formed on surfaces of the non-woven fabric. After being cooled to room temperature by a cooling roller, a highly reflective solar cell backsheet is obtained.

CROSS LAYER FIBER ENTANGLEMENT TO INCREASE STRENGTH OF 3D PART
20200307147 · 2020-10-01 ·

A printed sheet fiber entanglement apparatus entangles fibers from neighboring printed fibrous layers (e.g., sheets) with one another. As a stack of printed fibrous sheets is built up, periodically a holey plate is loaded against the top sheet of the stack. The guide plate may move the sheet down over the registration pins, and then an array of felting needles are thrust into the stack. An array of needles with upward and/or downward facing barbs is thrust thought holes in the guide plate into the stack through printed sheets closest to the guide plate. As the needles pushed into or are withdrawn from the stack, barbs on the felting needles intertwine fibers from the fibrous sheets through printed marking material and with neighboring sheets. The needle array may translate slightly between multiple thrusts so that a subsequent needling thrust may occur in a slightly new location.

Biodegradable Nonwoven With Self-Adhesive For Packaging
20240009957 · 2024-01-11 · ·

The present disclosure includes a composition and method of making a nonwoven that creates a self-adhesive during lamination that is suitable for use as an impermeable or almost impermeable packaging medium and is 100% biodegradable. Unlike other films that have difficulty in bonding to a substrate that may cause air bubbles and fisheyes, the present method of making a film, and related film composition needs no adhesive to bond to a substrate. In one aspect, PLA mono-component fibers are utilized at a specific blend to achieve impermeability and transparency and/or semi-transparency properties. The manufacture of the same is also disclosed.

Adhesive fabrication process for garments and other fabric products
10750805 · 2020-08-25 · ·

A process for fabricating a three-dimensional, multi-layered fabric product with a moisture barrier is provided. A partially seamed inner lining fabric assembly having at least a two-dimensional shape is laminated with a membrane barrier film having flaps left un-laminated to cover at least one seam. The inner lining fabric assembly is further seamed and flaps of the of the membrane barrier film overlapped into contact with each other and sealed to provide a continuous moisture barrier. A process for fabricating a stretchable section of a garment with a moisture barrier is also provided. At least a section of a garment is formed from fibers arranged in a pattern having a direction of stretch in one direction and a three-dimensional surface texture such that a portion of the fibers protrude above another portion of the fibers. The stretchable section is stretched in the direction of stretch. Segments of a membrane barrier film are adhered to an outer edge of the protruding portion of the fibers while the section is stretched in the direction of stretch, leaving intermediate segments of the barrier film free from adherence to the section. In this way, the intermediate segments of the membrane barrier film include slack that folds up to form ruches when the section is in a relaxed state.

Manufacturing of decorative surfaces

A method for manufacturing decorative surfaces includes, in order, the steps of a) inkjet printing an image on a first thermoplastic foil by jetting and UV curing one or more pigmented free radical UV curable inkjet inks on the first thermoplastic foil; b) applying on the inkjet printed image a second thermoplastic foil carrying a layer containing a vinylchloride-vinylacetate-vinylalcohol copolymer with the layer facing the inkjet printed image on the first thermoplastic foil; and c) heat pressing the first and second thermoplastic foils into a decorative laminate; wherein at least one of the first and second thermoplastic foils is transparent, and the one or more pigmented free radical UV curable inkjet inks contain a polymerizable composition having: 30 to 90 wt % of one or more compounds with one ethylenically unsaturated polymerizable group; 10 to 70 wt % of one or more compounds with two ethylenically unsaturated polymerizable groups; and 0 to 10 wt % of one or more compounds with three or more ethylenically unsaturated polymerizable groups.
