Abstract
The invention relates to a structural frame made from a composite material. The purpose of the invention is to obtain a structural frame with high mechanical performances while remaining simple in construction. This purpose is achieved in arranging sets of single-directional fibers in the main part of the structural frame at a predetermined angle. This system may be used as a structural frame particularly for an aircraft fuselage.
Claims8
A structural frame made from a composite material, designed particularly for an aircraft fuselage, comprising:
- an approximately plane annular main part, the main part including
- first sets of single-directional fibres forming an angle between approximately 25 degrees and 35 degrees from a circumferential axis of the frame, and
- second sets of single-directional fibres forming an angle between approximately −35 degrees and −25 degrees from the circumferential axis of the frame,
- the first and second sets being uniformly distributed over a the thickness of the main part;
- and
- a secondary part located on an outer peripheral edge around the main part and extending approximately perpendicular to the main part, and the secondary part includes only sets of single-directional fibres arranged approximately in a circumferential direction of the frame.
