In one embodiment, a method may comprise heating a composite material into a viscous form, wherein the composite material comprises a thermoplastic and a plurality of reinforcement fibers, wherein the plurality of reinforcement fibers is randomly arranged within the thermoplastic. The method may further comprise extruding a plurality of strands of the composite material, wherein extruding the plurality of strands causes the plurality of reinforcement fibers within each strand to align. The method may further comprise arranging the plurality of strands of the composite material to form a mold tool, wherein the mold tool is configured to mold a composite structure at a heated temperature, and wherein the mold tool comprises an anisotropic thermal expansion property, wherein the anisotropic thermal expansion property is based on an orientation of the plurality of reinforcement fibers within the mold tool.

The present application relates to a decoration member including a pattern layer provided on one surface of the substrate and including a convex structure or a concave structure arranged two-dimensionally, and a method for preparing the decoration member.

A method for making an aerodynamic element, particularly for an aircraft, including an external face and a plurality of parallel ribs and/or grooves formed on the external face, the method including making the element and its ribs and/or its grooves simultaneously with a mold, including a step to supply a film made of a deformable material that includes ribs and/or grooves complementary to the ribs and/or grooves of the element, a step to position the film on a wall of the mold, a step in which the element is molded, a step in which the element is separated from the mold simultaneously with the film, and a step in which the film is separated from the element.

A tool is configured to have a changeable shape. The tool comprises a thermoplastic polymeric material, resistive heating elements within the thermoplastic polymeric material, and a flexible casing encapsulating the thermoplastic polymeric material and resistive heating elements.

An apparatus for forming a flowable material against a prosthetic implant can comprise a mold body having an outer surface and an inner surface. The inner surface can define a mold cavity that is selectively configured to at least partially accept the prosthetic implant in a forming position. An inlet port can be configured on the mold cavity that extends between the inner and outer surfaces. The mold cavity can substantially conform to a profile of a bone opposing surface of the prosthetic implant such that a void is created between the inner surface of the mold body and the bone opposing surface of the prosthetic implant. The inlet port can be configured to permit introduction of the flowable material into the void and against the bone opposing surface of the prosthetic implant.

The present application relates to a decorative member including a color developing layer including a light reflective layer and a light absorbing layer provided on the light reflective layer; and a substrate provided on one surface of the color developing layer, wherein the light absorbing layer includes a copper oxide (Cu.sub.aO.sub.x).

Solution casting a nanostructure. Preparing a template by ablating nanoholes in a substrate using single-femtosecond laser machining. Replicating the nanoholes by applying a solution of a polymer and a solvent into the template. After the solvent has substantially dissipated, removing the replica from the substrate.

The present disclosure is directed methods for modifying molds of rotor blades of a wind turbine. In certain embodiments, the blade mold is constructed, at least in part, of a thermoplastic material optionally reinforced with a fiber material. In one embodiment, the method includes identifying at least one blade mold addition for the mold of the rotor blade and positioning the blade mold addition at a predetermined location of the mold of the rotor blade. Further, the blade mold addition is constructed, at least in part, of a thermoplastic material. Thus, the method includes applying at least one of heat, pressure, or one or more chemicals at an interface of the blade mold addition and the mold so as to join the blade mold addition to the mold. In further embodiments, the methods described herein are also directed repairing thermoplastic blade molds.
