Abstract:
1. A method implemented on a computer having a memory and a processor coupled to the memory for designing a composite material part with a curved surface ( 65 ) to which a plurality of stiffening elements oriented in planes substantially perpendicular to said curved surface are joined, including a design of a three dimensional (3D) fabric model defining contours of fabrics which are to be stacked to shape said composite material part from geometric references relating to said part with a curved surface ( 65 ) and to said stiffening elements, said design of the 3D fabric model comprising the following steps: generating, using the processor, references ( generating, using the processor, a planar surface ( associating the planar surface ( computing the fabric model in the surface ( carrying out any subsequent modification of the fabric model either in the surface ( wherein an intersection point ( wherein at least some of the steps of said method are performed using said processor.
