METHOD FOR DESIGNING PART MADE FROM COMPOSITE MATERIAL AND HAVING A CURVED SURFACE

摘要

The invention relates to a method for designing a composite material part with a curved surface (65) to which a plurality of stiffening elements will be joined, in which the design of a 3D fabric model comprises the following steps: generating a planar surface (63) developed in 2D of the surface (65) of the curved part in 3D as well as the same geometric references (71) in 2D as the references (51) of the surface in 3D; associating the surface (63) developed in 2D and the surface (65) in 3D as well as their geometric references (71, 51), such that any action in one of them is reflected in the other; initially computing the fabric model in the surface (63) developed in 2D; carrying out any subsequent modification of the fabric model either in the surface (63) developed in 2D or in the surface (65) in 3D.
