The present invention relates to composite materials and the use thereof as energy resistant, for example blast-resistant, materials. Preferred aspects of the invention relate to layered composite panels comprising solid foam materials which have both a blast attenuation function and an anti-ballistic function. In further aspects, the invention provides novel composite panels which are suitable for use as blast resistant and/or anti-ballistic materials. In some examples described, the layered composite panel comprises a polymeric material (10) bonded to a first solid open-cell foam panel (12), and a cured polymeric material (14) penetrates a surface of the first solid open-cell foam panel (12).

A component for a gas turbine engine according to an exemplary embodiment of the present disclosure can include a substrate, a thermal barrier coating deposited on at least a portion of the substrate, and an outer layer deposited on at least a portion of the thermal barrier coating. The outer layer can include a material that is reactive with an environmental contaminant that comes into contact with the outer layer to alter a microstructure of the outer layer.

Methods for forming sintered-bonded high temperature coatings over ceramic turbomachine components are provided, as are ceramic turbomachine components having such high temperature coatings formed thereover. In one embodiment, the method includes the step or process of removing a surface oxide layer from the ceramic component body of a turbomachine component to expose a treated surface of the ceramic component body. A first layer of coating precursor material, which has a solids content composed predominately of at least one rare earth silicate by weight percentage, is applied to the treated surface. The first layer of the coating precursor material is then heat treated to sinter the solids content and form a first sintered coating layer bonded to the treated surface. The steps of applying and sintering the coating precursor may be repeated, as desired, to build a sintered coating body to a desired thickness over the ceramic component body.

Porous hybrid inorganic/organic materials comprising ordered domains are disclosed. Methods of making the materials and use of the materials for chromatographic applications are also disclosed.

A coated turbomachine component includes a ceramic component body having a principal surface. The component includes a high temperature coating. The high temperature coating includes a sintered coating body bonded directly to and intimately contacting the principal surface of the ceramic component body. The sintered coating body has a minimum porosity adjacent the principal surface and a maximum porosity at a location further from the principal surface, as taken along an axis orthogonal to the principal surface.

One variation of a method for fabricating a dermal heatsink includes: fabricating a substrate defining an interior surface, an exterior surface opposite the interior surface, and an open network of pores extending between the interior surface and the exterior surface; activating surfaces of the substrate and walls of the open network of pores; applying a coating over the substrate to form a heatsink, the coating comprising a porous, hydrophilic material and defining a void network; removing an excess of the coating from the substrate to clear blockages within the open network of pores by the coating; hydrating the heatsink during a curing period; heating the heatsink during the curing period to increase porosity of the coating applied over surfaces of the substrate; and rinsing the heatsink with an acid to decarbonate the coating along walls of the open network of pores in the substrate.

A multilayer film includes an outer foam layer and a gas barrier layer. The multilayer film may also include at least one tie layer and at least one inner layer, and can be configured to have various film layer constructions. For example, the multilayer film can be configured as a five-layer, six-layer, or seven-layer films. The multilayer film can provide unique texture, softness, quietness, gas barrier properties, light weight and low cost per volume. Further, one or more layers of the multilayer film can contain a vinyl-bond rich triblock copolymer to provide sound absorbing properties.

Thin PTFE layers are described having little or no node and fibril microstructure and methods of manufacturing PTFE layers are disclosed that allow for controllable permeability and porosity of the layers. In some embodiments, the PTFE layers may act as a barrier layer in an endovascular graft or other medical device.
