A system and method for in-process inspection of a fused-filament fabricated part comprises an extrusion head and an associated laser profilometer for scanning and generating two-dimensional surface scans of additively deposited layers of the fused-filament fabricated part following material deposition of the layer by the extrusion head and prior to the deposition of subsequent layers. The surface scans are used to inspect the fused-filament fabricated part for defects during, or subsequent to, the fabrication of the part, either layer-by-layer or through a reconstruction of the part in three dimensions.

System for in-process inspection of fused-filament fabricated parts and associated methods

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.

Additively manufactured septa for acoustic panels

A fluid applicator for use in a fluid application system includes a base plate comprising at least one rail and a housing slidably coupled to the base plate. The fluid applicator also includes a plurality of fluid permeable pads positioned within the housing and a fluid delivery conduit coupled to the base plate and to the housing. The fluid applicator further includes an actuator configured to selectively move the housing and the plurality of pads along the rails between a first position and a second position. The plurality of fluid permeable pads are in flow communication with the fluid delivery conduit in the first position, and the plurality of fluid permeable pads are prevented from being in flow communication with the fluid delivery conduit in the second position.

Apparatus and methods for use in applying a fluid to a surface

A manufacturing method includes locking a material to be cut against a cutting bed, stabilizing the material against the cutting bed, and cutting the material.

Stabilizing shoe, manufacturing apparatus, and manufacturing method

A fluid application system includes a pair of identical, spaced apart, fluid applicators that each include a fluid permeable pad saturated with fluid. In one implementation, each applicator includes a pair of conduits coupled to a base plate, wherein each conduit includes a slot configured to receive an end of the pad. In another embodiment, each applicator defines a reservoir between adjacent plates and channels fluid from the reservoir though openings in the plate to the pad. In another implementation, each of the applicators includes a base plate, a conduit coupled to the base plate, and a housing slidably coupled to the base plate. The housing includes a plurality of pads and is moveable to selectively prevent fluid flow between the conduit and the pads in a first position or to couple the pads in fluid communication with the conduit in the second position.

A composite structure assembly includes a composite core including a flexible base and a plurality of cells extending from the flexible base. The composite core is conformable to different shapes. The plurality of cells are configured to move in response to movement of the flexible base. At least one of the plurality of cells may include a central column connected to a first flared end and a second flared end that is opposite from the first flared end.

Composite structure assembly having a conformable core

A composite structure assembly and method of forming a composite structure assembly is provided. The composite structure assembly includes a composite core including a first cell layer having a plurality of first cells and a second cell layer having a plurality of second cells. The first cell layer is adjacent to the second cell layer. The plurality of first cells are fluidly interconnected with the plurality of second cells.

Composite structure assembly having an interconnected layered core

A drape forming apparatus for that includes a forming tool including an upper forming surface and a side forming surface extending from the upper forming surface. The forming tool receives a layer of composite material over the upper forming surface. The apparatus includes a flange forming device including an upper plate, a lower plate, and a receiving slot defined therebetween. The receiving slot receives a flange portion of the layer of composite material, and the flange forming device is translatable relative to the forming tool such that the flange portion of the layer of composite material is withdrawn from the receiving slot and draped over the side forming surface. The apparatus includes a pressurized bladder that extends over the forming tool and the upper plate. The pressurized bladder forces the flange portion against the side forming surface as the flange forming device translates relative to the forming tool.
