The present invention proposes an apparatus for demolding materials produced by means of the processing technique called freeze-casting. More specifically, it addresses to the application of a linear actuator to perform the sliding/extraction of solid-state parts in low-temperature condition from the containers used as a mold for manufacturing parts using freeze-casting. The device allows pressure to be applied to the material to be removed, resulting in ejection. The artifact also allows the displacement of the element with controlled displacement speed, providing the achievement of defect-free materials.

System for demolding materials obtained by means of the freeze-casting technique characterized in that it comprises a source of compressed air (1), a pressure regulator filter (2) coupled with a manometer (3), a directional valve (4), an actuator linear (5), a baton (6), a flow regulating valve (7), a fastening means (8), a metallic support (9) and a chamber for receiving the cooled material (10).

A method and device for removal of a molded sample from a mold with minimal or no damage to the molded sample. The device includes a drill configured for perforating a wall of the mold with the formation of a through aperture, a shroud passageway through or adjacent the drill, and a passageway from a source for pressurized fluid leading to the shroud passageway. The shroud passageway is configured whereby fluid such as air is applied therethrough simultaneously with perforation operation of the drill. Air directed through the aperture is pressurized and comes into effective contact with the molded sample whereby the molded sample is prevented from being more than minimally contacted with the drill and caused to be removed from the mold.

A composite material structure can be constructed using an airforming process that includes filling the inflated support mold with a fluid structural material and allowing the fluid structural material to harden within the support mold. Additional steps can include inflating the support mold with a first fluid, forming fluid escape outlets in the support mold, and removing the support mold after allowing the fluid structural material to harden. The first fluid can be air, the support mold can be a fiberglass resin, and/or the fluid structural material can be a concrete composite material. Fluid can escape through the fluid escape outlets during the filling. The finished structure can include multiple structural components formed from a homogenous concrete composite material and having curved and non-planar geometries. The concrete composite material can include aluminum alloy fibers.
