Abstract
A wide-body aircraft is disclosed with a fuselage section that includes a set of side-by-side fuselage lobes having a fuselage skin. A first woven composite preform positioned at a first intersection of the set of side-by-side fuselage lobes located at a first cusp of the side-by-side fuselage lobes. A second woven composite preform positioned at a second intersection of the set of side-by-side fuselage lobes located at a second cusp of the side-by-side fuselage lobes. Each of the first and second woven composite preforms are configured to receive a structural component, such that each of the first and second woven composite preforms accommodates vertical load imparted through the structural component.

A fuselage comprising:
- a wide-body fuselage section comprising a set of side-by-side fuselage lobes having a fuselage skin;
- a first woven composite preform positioned at a first intersection of the set of side-by-side fuselage lobes and located at a first cusp of the set of side-by-side fuselage lobes;
- and
- a second woven composite preform positioned at a second intersection of the set of side-by-side fuselage lobes and located at a second cusp of the set of side-by-side fuselage lobes,
- wherein each of the first and second woven composite preforms are configured to receive a structural component, such that each of the first and second woven composite preforms accommodates a vertical load imparted through the structural component,
- wherein the first and second woven composite preforms are co-cured with the fuselage skin of the set of side-by-side fuselage lobes to maintain a desired shape, and
- wherein the first and second woven composite preforms are substantially Y-shaped.
