Composite structures window belt and method of making

Claim 2

A window containing section of a composite structure for fuselage comprising: a row of spaced-apart reinforced plastic window frames, means on the window frames for securing windows within the frames, a layer of reinforcing filaments coated with a resin wound around a periphery of each window frame, a core of honeycomb extending between window frames, a reinforcing filament wound resin impregnated inner shell, and a reinforcing filament wound resin impregnated outer shell to make up a shaped composite structural section.

Claim 3

A window containing section of a composite structure as in claim 1 wherein the window frames are in sections to be joined by the filaments encircling the periphery.

Claim 4

A window containing section of a composite structure as in claim 2, further comprising: the window frames having laterally outwardly extending U-shaped legs, a reinforced plastic cover to mate with the ends of the legs, and a layer of reinforcing filaments coated with a resin wound around the periphery of the mating plastic cover.

Claim 5

A window containing section of a composite structure as in claim 1 wherein the window frames are each of a one-piece, essentially Z-shaped construction.

Claim 6

An elongated section of a composite structure containing windows, with the structure comprising: a series of spaced-apart, essentially diamond-shaped window frames each made up of parts of reinforced plastic, mating connections where the parts join, laterally outward extending U-shaped legs, a tapered flange to extend interally inward, a layer of reinforcing filaments coated with a resin wound around the outer periphery of the joined parts, a series of reinforcing enlargements to accept a fastener for retaining a window in the frame with the enlargements located along the inner side of the leg that is furthest from the flange, a cover plate of reinforced plastic to extend between the ends of the legs, and a layer of reinforcing filaments coated with a resin wound around the outside of the cover plate; a honeycomb core to extend between and around the window frames; a reinforcing filament wound resin impregnated inner shell; and a reinforcing filament wound resin impregnated outer shell with all the components making up an elongated section of a composite structure containing spaced-apart windows.

Claim 7

An elongated section of a composite structure containing windows, with the structure comprising: a series of spaced-apart, essentially diamond-shaped window frames each made up of parts of reinforced plastic, mating connections where the parts join, laterally outward extending U-shaped legs, a tapered flange to extend interally inward, a layer of reinforcing filaments coated with a resin wound around the outer periphery of the joined parts, a series of reinforcing enlargements to accept a fastener for retaining a window in the frame with the enlargements located along the inner side of the leg that is furthest from the flange, a cover plate of reinforced plastic to extend between the ends of the legs, and a layer of reinforcing filaments coated with a resin wound around the outside of the cover plate; a honeycomb core to extend between and around the window frames; a reinforcing filament wound resin impregnated inner shell; and a reinforcing filament wound resin impregnated outer shell with all the components making up an elongated section of a composite structure containing spaced-apart windows.

Claim 8

An elongated section of a composite structure containing windows, with the structure comprising; a series of spaced-apart, essentially diamond-shaped window frames each made up of reinforced plastic and having a modified Z-shaped cross section; a series of reinforcing enlargements to accept a fastener for joining a window to the frame with the enlargement located along the inner side of an outer leg of the modified Z-shape; a honeycomb core to extend between and around the window frames; a reinforcing filament wound resin impregnated inner shell; and a reinforcing filament wound resin impregnated outer shell with the components making up an elongated section of a composite structure containing windows.

Claim 9

An elongated section of a composite structure containing windows, with the structure comprising; a series of spaced-apart, essentially diamond-shaped window frames each made up of reinforced plastic and having a modified Z-shaped cross section; a series of reinforcing enlargements to accept a fastener for joining a window to the frame with the enlargement located along the inner side of an outer leg of the modified Z-shape; a honeycomb core to extend between and around the window frames; a reinforcing filament wound resin impregnated inner shell; and a reinforcing filament wound resin impregnated outer shell with the components making up an elongated section of a composite structure containing windows.

Claim 10

An elongated section of a composite structure containing windows as in claim 6, further comprising: a layer of reinforcing filaments coated with a resin wound around the outer side of each window frame.
