Abstract
A method for manufacturing a structural element for a fuselage of an aircraft. To improve the manufacture of structural elements, a method includes laying up textile material members on a mandrel to form a plurality of structural element preforms that are space apart along an extended direction of the mandrel. The structural element preforms form closed loops and are subsequently cured to obtain annular structural elements. The annular structural elements are used as basic building blocks for stiffening panel members or are directly used as structural frame elements reinforcing cut-outs in a fuselage for windows and/or doors.
Claims13
A method for manufacturing a structural element for a fuselage of an aircraft, the method comprising steps of:
- a on a mandrel that extends in a longitudinal direction, laying up a plurality of textile material members that are spaced apart next to each other along the longitudinal direction to form a plurality of structural element preforms;
- and
- b) curing the structural element preform, to obtain a structural element;
- wherein at least one structural element preform is laid up by laying up the textile material members on the mandrel such that the structural element preform is double curved, wherein a first curvature is formed by continuously displacing the textile material members during laying up along a longitudinal axis up to a maximum displacement outside of a cross-sectional plane through the mandrel that is orthogonal to the longitudinal direction, and a second curvature is formed by laying up the textile material members around a circumferential surface of the mandrel.
