An imprint method includes arranging imprint material as droplets on shot region of substrate, bringing the imprint material on part of the shot region into contact with pattern region of mold and then enlarging contact region between the imprint material and the pattern region to whole region of the shot region, and curing the imprint material. in the arranging, in each of local regions located in radial direction from the part of the shot region, the imprint material is arranged such that directional drop density of the imprint material on line parallel to direction orthogonal to the radial direction and with droplets of the imprint material present thereon is smaller than that of the imprint material on line parallel to the radial direction and with droplets of the imprint material present thereon.

A tooling assembly for manufacturing a porous composite structure. The tooling assembly includes a first tooling member and a second tooling member. The first tooling member includes a first body that defines a first internal volume and a first inlet. The first inlet is fluidly coupled with the first internal volume. The first tooling member also includes a first tooling surface that defines a plurality of first perforations that are fluidly coupled with the first internal volume. The second tooling member includes a second body that defines a second internal volume and a second inlet. The second inlet is fluidly coupled with the second internal volume. The second tooling member also includes a second tooling surface that defines a plurality of second perforations that are fluidly coupled with the second internal volume.

Described herein are expandable foaming molds. The foaming molds described herein permit mold boundaries to expand along with the expanding polymer and thereby conform to the foaming dynamics of the polymer material. By modifying the temperature and pressure applied to the mold devices described herein, the properties of the resulting foamed polymer can be fine-tuned for specific applications.

Devices, systems, and methods for modular molding of wind turbine blades are provided. Methods of molding wind turbine blades using a modular molding assembly or system and methods of substituting molds are provided. In some embodiments, a modular assembly includes a first base frame and a second base frame hingedly coupled to one another, a first tooling frame disposed on the first base frame, a second tooling frame disposed on the second base frame, a first shell mold coupled to the first tooling frame, and a second shell mold coupled to the second tooling frame. The first shell mold has a first mold surface and a first perimeter and the second shell mold has a second mold surface and a second perimeter. When in an open configuration, the first base frame is coplanar with the second base frame, and, in a closed configuration, the first perimeter contacts the second perimeter.

Within examples, elastomeric apparatuses for use in manufacture of a composite component, and methods for altering a surface rigidity of an elastomeric apparatus for use in manufacture of a composite component are described. In one example, an elastomeric apparatus comprises an elastomer housing, and a plurality of magnets within the elastomer housing at predetermined positions to provide surface rigidity to the elastomer housing based on one or more alignments of certain magnets of the plurality of magnets due to magnetic forces. An increase in temperature causes a loss in one or more of the magnetic forces of one or more of the plurality of magnets resulting in a reduction of stiffness of the elastomer housing at corresponding predetermined positions.

A method for manufacturing a wing box for aircraft comprises the steps of arranging, on a curing surface, a first panel of composite material, alternately arranging, on the first panel, along a transverse direction, a rib of non-polymerized composite material and a tool comprising a central part, a bottom part and a top part, wherein the central part of each tool is interposed between said bottom part and the top part and may be extracted in a transverse direction, arranging a second panel of composite material by putting said second panel in contact with the flanges of each rib, pulling out the central part of each tool along the transverse direction and removing the top part and the bottom part of each tool, and subjecting the first panel, the second panel, and each rib to a curing process in autoclave with vacuum bag.
