Multiple processes for preparing porous articles are described. The porous articles can be in a wide array of shapes and configurations. The methods include providing a soluble material in particulate form and forming a packed region from the material. The methods also include contacting a flowable polymeric material with the packed region such that the polymeric material is disposed in voids in the packed region. The polymeric material is then at least partially solidified. The soluble material is then removed such as by solvent washing to thereby produce desired porous articles. Also described are systems for performing the various processes.

Tunable thermoplastic polymer sealants and tunable conductive thermoplastic polymer sealants, and edge seals and fillet seals produced from such sealants; and substrates, components and objects comprising the tunable edge seals and fillet seals, and methods for making and applying such edge seals and fillet seals are disclosed.

Systems and methods are provided for applying cold spray erosion protection to an airfoil. One embodiment is a method for applying an abrasion coating to a fiber-reinforced composite substrate. The method includes applying a bond layer to the fiber-reinforced composite substrate by emitting, with a supersonic nozzle of a High Pressure Cold Spray (HPCS) system, a first gas stream including a first metal powder at a first speed below supersonic speed. The method further includes applying a cold spray deposit layer to the bond layer by emitting, with the supersonic nozzle, a second gas stream including a second metal powder at a second speed above supersonic speed.

An exterior trim part comprising at least a fibrous layer forming the carrier, characterized in that at least one surface consists of a splat polymer coating deposited at least along a portion of the surface forming a splat polymer coating layer.

A cloud tower (11) receives microscopic particles (18) impelled by an inert gas (17) for deposition on a porous substrate (29) having vacuum (34) disposed on opposite side. To alter the size and/or shape of the deposition field without changing the entire tower structure, a pair of flaps (43, 44) are hinged (47, 48) on one side or on a pair of opposed sides of the cloud primary tower. Another embodiment places selectable tower inserts (36, 38) within the primary tower structure, fitting therein and sealing thereto.
