A structural component with at least two side members has a support structure that includes a partition with multiple curved portions forming cells. The partition connects to the side members and extends between the side members at least partially along straight lines. The partition may extend along one or more straight lines from one side member to the other. One structural component is a container with a wall about the internal support structure. The container cells may be formed with a core structure. The core can include a permeable storage material and may be retained after formation, or may be removed. In some cases the container wall has generally planar surfaces, which may include surface undulations. Core structures are also provided for forming structural components. Formation can include casting a material about a core structure within a mold to form a partition extending between two or more sides.

A durable light weight, high temperature acoustic CMC liner system. A thin ceramic matrix composite skin, also referred to as a facesheet, forms an outer layer of a cell in the CMC liner system, forming the boundary with the flow of hot gases in the exhaust. A backplate forms the opposite boundary for the cell. The truss structure is formed between the backplate and the facesheet and provides the cell with strength. When the CMC system replaces the metal liner, the backplate thickness is increased so that it is about the thickness of the liner system that it replaces. The truss structure extends between the backplate and the facesheet, forming channels or volumetric spaces. These channels or volumetric spaces are filled with high temperature air permeable acoustic materials that attenuate sound propagated by cooling air in the acoustic range.

The present disclosure provides a cloth comprising: a gas sheet having multiple individual gas cells formed therein, each cell having substantially a sphere shape, the gas sheet being made of an elastic material to having a good stretchability, each gas cell having a gas filled therein, species of the gas corresponding to an application of the cloth, the gas cells being continuously connected in a matrix form; and an inshell and an outshell attached to inner and outer sides of the gas sheet respectively.

An automatic machine for providing corrugated sheet-like elements having a component for the continuous corrugation of a ribbon in motion in a longitudinal direction. The corrugation component includes an upper conveyor and a lower conveyor. The upper conveyor includes a plurality of upper abutment elements that are extended substantially transversely to the longitudinal direction of motion of the ribbon. The lower conveyor includes a plurality of lower abutment elements that are extended substantially transversely to the longitudinal direction of motion of the ribbon. The upper abutment elements are intercalated between the lower abutment elements in a work area. The upper abutment elements each comprise include a flap, which has, in the end adapted to make contact with the ribbon, at least one portion that has a grip component.

Composite materials having superior material properties useful as impact absorbing devices can be fabricated by embedding a lattice structure (e.g., polymer lattice structure) within a foam, so that the foam reinforces the lattice structure under impact. Materials and dimensions of the foam and the lattice structure may be selected to achieve composite materials having tailored impact absorbing elastic and/or viscoelastic responses over a wide range of temperatures.

A method for using an attachment tag with a product includes affixing an adhesive layer of the attachment tag to the product. The attachment tag includes an elastomer portion and a tag portion bonded to the elastomer portion along a bond zone, wherein the adhesive layer is disposed on the tag portion. The method also includes expanding the elastomer portion by at least partially separating at least two of a plurality of leg segments of the elastomer portion and securing the expanded elastomer portion around at least a portion of the product.

To make membranes, a plurality of membrane substrates are each wetted with a curable liquid mixture, arranged in a stack such that every pair of substrates are separated by at least one film, and moved simultaneously through a common curing region. Each wetted substrate sheet may be sandwiched between two films. After curing, the stack comprises two or more membranes with each pair of membranes separated by a film. An apparatus for making membranes comprises at least two substrate feeding devices, at least one film feeding device, one or more chemical wetting devices, a curing region, optionally, a stack separating region, and, optionally, a membrane binding or fusing region. Membrane production rate may be increased while the curing energy required per unit area of membrane is decreased. The method can make, for example, ion exchange membranes.

In a resin sandwich panel, the two resin skin material sheets have peripheral edge portions thereof joined to each other so as to form an internal hollow portion. The resin core material is disposed in the hollow portion. At least one of surfaces of the resin core material opposing the two resin skin material sheets has a groove portion extending across the entire surface, and a depression communicating with the groove portion. At least one of the two resin skin material sheets additionally has an atmosphere-opened through-hole provided in a thickness direction thereof. When the one of the surfaces of the resin core material and the corresponding resin skin material sheet are surface-to-surface adhered to each other in the hollow portion, air between the surfaces and the skin material sheet is guided to the depression via the groove portion, and exhausted out of the atmosphere-opened through-hole.

Implementations described herein include films with maintained or decreased light transmittance despite a reduction in gauge. In particular, one or more implementations include a multi-layer film with each layer having differing opacity agents. The combination of the two different opacity agents in two different layers can have a synergistic effect that provide decreased light transmittance. Indeed, in one or more embodiments a multi-layer film with differing opacity agents in each layer has a decreased light transmittance despite a reduction in gauge and opacity agents.

Co-cured urethane and vinyl ester, epoxy, or unsaturated polyester gel coats having improved toughness and flexibility compared with conventional polyester gel coats are disclosed. The gel coats, which have 10-50 wt. % urethane content, adhere well to structural layers and can be used in a traditional in-mold process. Co-cured elastomeric coatings comprising from 50 to 95 wt. % of a urethane component and an unsaturated polyester, epoxy, or vinyl ester are also disclosed. Unlike conventional urethane coatings, the elastomeric coatings adhere well to structural layers and can be used in a traditional in-mold process. Castings or structural layers comprising a reinforced thermoset of co-cured urethane and vinyl ester, epoxy, or unsaturated polyester components, including 10-95 wt. % of the urethane component, are also described. The invention includes in-mold processes for making laminates that utilize the gel coats, elastomeric coatings, and/or structural layers. The in-mold process gives flexible, durable, urethane-containing laminates having good interlayer adhesion.
