A component, including a part, comprising a honeycomb-like structure formed from at least a seamless resin-infused fiber composite material. The honeycomb-like structure includes a first plurality of honeycomb-like cells, and a second plurality of honeycomb-like cells, different than the first plurality of honeycomb-like cells.

Light weight fibrous veils are incorporated into the uncured composite face sheets of a honeycomb sandwich structure in order to reduce the lateral crushing of the honeycomb (core crush) that occurs during curing of the uncured structure in an autoclave or vacuum bag system. The light weight fibrous veils act as friction-promoting layers to reduce the relative movement of the uncured face sheets that leads to core crush during the curing process.

Disclosed embodiments relate to trays typically comprising a composite internal structure, a thermoplastic frame typically located about the composite internal structure, and two cover sheets forming the upper and lower tray surfaces. The composite internal structure may be a corrugated composite structure in some embodiments. In other embodiments, the composite internal structure may comprise a series of composite elements (which might act a beams or struts). The cover sheets may comprise thermoplastic material, and in some embodiments, the cover sheets may comprise composite material (for example the same as for the corrugated composite structure). In some exemplary embodiments, the thermoplastic frame and the composite internal structure may have the same thermoplastic material, and they may be joined together to have a plurality of homogeneous connective attachments.

A method of constructing a building comprising the steps of attaching a first panel to a second panel. The first panel is one of a single plenum panel and a multi-plenum panel and the second panel is one of a single plenum panel and a multi-plenum panel.

Disclosed is a method for producing a profiled semi-finished plastic product from flexible web material, including: providing a plurality of webs of flexible material, continuously and simultaneously feeding the webs of material to and along a plurality of shaping pieces arranged next to each other, folding each web of material around a respective shaping piece to form a body and an edge strip which projects transversely with respect to the body,causing the edge strips of different webs of material to at least partly cover each other, impregnating the webs of flexible material provided or the assembly of webs of material with folded-over edge strips covering each other with a hardenable unit, causing the hardenable unit to harden to form the profiled semi-finished plastic product, wherein open spaces remain between two neighbouring bodies and edge strips.

An example method for manufacturing a multicellular structure for acoustic damping is described that includes applying a porogen material to a solid support, inserting a multicellular frame into the solid support and through the porogen material so as to fill cells of the multicellular frame with the porogen material, fusing the porogen material, removing the multicellular frame from the solid support, and the multicellular frame contains a suspended fused porogen network attached to walls of the cells of the multicellular frame. The method also includes applying a solution to the suspended fused porogen network in the cells of the multicellular frame to percolate the suspended fused porogen network, curing the solution, and removing the suspended fused porogen network from the multicellular frame resulting in porous septum membranes of the cured solution in cells of the multicellular frame.

A damper is formed by a housing member wherein an outer cylinder portion and an inner cylinder portion that are cylindrically formed are concentrically disposed, and respective lower ends are connected to each other at a bottom portion, and at an upper end of the outer cylinder portion, an open end portion is formed, and a groove portion is formed on an inner periphery; and a lid member provided with a rotor inserted from the open end portion, and housed in the housing member, and formed with a projection portion engaging the groove portion. A thin wall portion which is thinner than the outer cylinder portion is formed in a vicinity of a groove portion side in the outer cylinder portion.

A method and apparatus to treat a dried unfired article comprising a ceramic precursor composition substantially held together by a binder, to be resistant to binder soluble solvent based processing. The method includes depositing a fluid on the article surface, and polymerizing the deposited fluid to form a polymer thin layer on the surface. The fluid may be an aerosol, a vapor, a fog, a mist, a smoke, or combinations thereof. An apparatus to perform the method and an article resistant to binder soluble solvent based processing are also provided. The article can be an unfired honeycomb body that includes a dried composition of ceramic precursor substantially held together by a binder and a layer disposed on a surface of the unfired honeycomb body. The surface to be exposed in the green state to a binder soluble solvent and the layer protects the binder from solubilization by the solvent.

A unitary core panel for a composite sandwich structure includes a plurality of cell walls defining a plurality of core cells, the plurality of cell walls extending across a thickness of the core, the plurality of core cells including one or more defined structural nonuniformities resulting in nonuniform properties of the core panel. A method of forming a core panel for a composite sandwich structure includes determining structural requirements of the core panel, designing the core panel to satisfy the structural requirements with one or more local nonuniformities in the core panel, and manufacturing the core panel as a unitary core panel with the one or more local nonuniformities.
