<P>PROBLEM TO BE SOLVED: To provide a process for production of an aircraft panel made of double-curved composite material to remedy the drawbacks of the prior art. <P>SOLUTION: This process, in which a panel is obtained from a three-dimensional preform that includes fibers that are distributed in a defined arrangement, includes manufacturing a flat fiber preform 22, and deforming the flat preform 22 in such a way as to produce the three-dimensional preform, with the fibers following trajectories suitable for the flat preform in such a way as to obtain the defined arrangement of the fibers after deformation. <P>COPYRIGHT: (C)2013,JPO&INPIT |
