A method is provided for manufacturing a container. During this method, a baffle is provided. The baffle is configured from or otherwise includes baffle thermoplastic material. A sidewall is formed using an additive manufacturing device. The sidewall is bonded to the baffle during the forming of the sidewall. The sidewall circumscribes the baffle. The sidewall is configured from or otherwise includes sidewall thermoplastic material. The container includes an internal chamber, the baffle and the sidewall. The sidewall forms an outer peripheral boundary of the internal chamber. The baffle is arranged within the internal chamber.

This method is for manufacturing a fan blade rotor which includes an annular rotation support ring around a rotary shaft, a permanent magnet provided alongside the rotation support ring in the radial direction, and a composite material for integrally binding the rotation support ring and the permanent magnet, the method including: a step S1 for arranging the rotation support ring and the permanent magnet side by side in the radial direction; steps S2-S4 for spirally winding, on the rotation support ring and the permanent magnet arranged side by side being as a core, the composite material being an uncured composite material including a reinforcement fiber impregnated with an uncured resin with the fiber direction of the reinforcement fiber set as a longitudinal direction; and a step for curing the resin included in the composite material.

Aircraft window assemblies and methods. The aircraft window assemblies comprise a window frame configured to support a window pane on an aircraft skin about a window aperture defined in an aircraft skin. The window frame includes a base formed of a continuous fiber reinforced thermoplastic composite and at least one overmolded feature molded to the base. The base defines a central aperture and includes circumferential flange portion configured to support the base on the aircraft skin surrounding the window aperture and a skirt portion extending inwardly from the circumferential flange portion and surrounding the central aperture. The skirt portion is non-planar with the circumferential flange portion and comprises a support surface for the window pane. The methods comprise forming the window frame, which comprises stamp-forming the base of the window frame from a continuous fiber reinforced thermoplastic composite sheet and overmolding the at least one overmolded feature to the base.

A method allows for preparation of CNT nanocomposites having improved mechanical, electrical and thermal properties. Structured carbon nanotube forms such as sheet, yarn, and tape are modified with -conjugated conductive polymers, including polyaniline (PANI), fabricated by in-situ polymerization. The PANI modified CNT nanocomposites are subsequently post-processed to improve mechanical properties by hot press and carbonization.

A three-dimensional electronic, biological, chemical, thermal management, and/or electromechanical apparatus can be configured by depositing one or more layers of a three-dimensional structure on a substrate. Such a three-dimensional structure can include one or more internal cavities using an additive manufacturing system enhanced with a range of secondary embedding processes. The three-dimensional structure can be further configured with structural integrated metal objects spanning the internal cavities (possibly filled with air or even evacuated) of the three-dimensional structure for enhanced electromagnetic properties.

Continuous fiber tow structures are used to form lattice reinforcing bodies to be embedded in a molded polymer matrix. The lattice structures are formed and shaped to reinforce a portion of a predetermined three-dimensional article. Optionally, some or all of the tow members of the structure may be formed with internal vascular passages for passage of a heat transfer fluid through the structure in the function of the molded polymer article. A liquid polymer is molded around the lattice structure, fully embedding the structure. The liquid polymer which may contain short-reinforcing fibers, is then solidified to form the composite reinforced polymer article. And connections may be made to the composite article for the flow of the fluid through vascular passages in the lattice structure within the article.
