摘要： Systems and methods are provided for septa for acoustic cells. One embodiment is a method that includes fabricating a septum of a cell of an acoustic panel, by heating a material into a molten material, depositing the molten material to form a lower chamber of the septum that extends vertically upwards and includes an entry, iteratively depositing layers of the molten material, each layer comprising a filament at the entry that includes overhangs with respect to vertically adjacent layers, and forming openings at locations of the overhangs.

摘要： Provided are composite feedstock strips for additive manufacturing and methods of forming such strips. A composite feedstock strip may include continuous unidirectional fibers extending parallel to each other and to the principal axis of the strip. This fiber continuity yields superior mechanical properties, such as the tensile strength along strip's principal axis. Composite feedstock strips may be fabricated by slitting a composite laminate in a direction parallel to the fibers. In some embodiments, the cross-sectional shape of the slit strips may be changed by reattributing material at least on the surface of the strips and/or by coating the slit strips with another material. This cross-sectional shape change may be performed without disturbing the continuous fibers within the strips. The cross-sectional distribution of fibers within the strips may be uneven with higher concentration of fibers near the principal axis of the strips, for example, to assist with additive manufacturing.

Material is passed through at least one perforation and movement of the ribbon cuts the material. A further embodiment comprises a disk including one or more blade structures, each forming at least one cavity. Material is passed through at least one cavity and a rotational movement of the disk cuts the material. A further embodiment comprises a slider-crank mechanism including a slider coupled to a set of parallel rails of a guide shaft. The slider moves along a length of the rails to cut the material. Yet another embodiment comprises one or more rotatable blade structures coupled to at least one rod. The rotation of the blade structures causes the blade structures to intersect and cut extruded material during each rotation.

摘要： Provided are composite feedstock strips for additive manufacturing and methods of forming such strips. A strip may include continuous fibers extending parallel to the principal axis of the strip. The cross-sectional distribution of these continuous fibers may be uneven. Specifically, the fibers may be concentrated near the center of the strip and may be positioned away from at least some portions of the strip surface. A strip may be formed by laminating a layup of one or more fiber-containing plies and one or more of resin plies. The position of the different types of plies in the layup is used to control distribution of the fibers and other materials within the strip. The laminated sheet is slit into multiple strips in a direction parallel to the continuous fibers. The cross-sectional profile of the slit strips may be later changed without disturbing orientation of the continuous fibers.
