The invention relates to a method for producing a grid made of composite material for straightening an air flow for an aircraft turbine engine. The described method is based on the use of longitudinal members (301) which have recesses (303) to allow the penetration of connecting elements (304) into said recesses during the manufacture of the grid.

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 for forming a fiber-reinforced thermoplastic control surface includes forming first and second skins from a fiber-reinforced thermoplastic resin. The method further includes overmolding fiber-reinforced thermoplastic features onto the first skin and/or second skin, including stiffener structures, sidewalls, and/or hinges. The method further comprises welding or consolidating the first and second skins together, along with the associated internal features overmolded thereon to form a single-piece, stiffened, fiber-reinforced thermoplastic control surface.
