Abstract
A number of integrated floor structures made of lightweight composite materials for use in an aircraft are disclosed. Generally, each of such floors includes a top-layer skin, a bottom-layer skin disposed below the top-layer skin and a first structural core disposed between the top-layer skin and the bottom-layer skin, the first structural core being composed of a honeycomb composite material. One or more denser structural cores can also be incorporated at strategic locations.
Claims32
An integrated floor portion made of lightweight composite materials for use in an aircraft comprising:
- a top-layer skin;
- a first structural core disposed below the top-layer skin, the first structural core being composed of a honeycomb composite material;
- a second structural core disposed below the first structural core, the second structural core being composed of a honeycomb composite material that is less dense than the first structural core;
- a bottom-layer skin disposed below the second structural core;
- and
- an attachment structure embedded within and running along a length of the floor portion to at least partially attach at least one seat to the floor portion.

An integrated floor portion for use in an aircraft, comprising:
- a top-layer skin;
- a high density honeycomb core disposed below the top-layer skin;
- a low-density honeycomb core disposed below and secured to the high-density honeycomb core;
- a bottom-layer skin disposed below the low-density honeycomb core;
- a hole through the integrated floor portion substantially perpendicular to an upper surface of the floor;
- an upper galley mount disposed above the top-layer skin surrounding the hole;
- an intercostal disposed below the bottom-layer skin surrounding the hole;
- and
- a fastener to tie the upper galley mount to the intercostal.

An integrated floor portion for use in an aircraft, comprising:
- a top-layer skin;
- first honeycomb composite structural means disposed below the top-layer skin and secured to the top-layer skin for providing structural support;
- second honeycomb composite structural means disposed below the first structural means and secured to the first structural means;
- a bottom-layer skin disposed below the second structural means and secured to the second structural means;
- attachment means embedded within and running along a length of the floor portion for attaching at least one seat to the integrated floor portion.
