ABSTRACT:
The present invention relates to a process for manufacturing pieces of revolution made of three-dimensional material, of which the generatrix has at least one concave part, said process consisting in making a support mandrel provided with rows of pins defining therebetween longitudinal corridors and circumferential corridors, in disposing superposed layers of yarns in said corridors by winding and by filling, in densifying the assembly thus obtained, and, finally, in eliminating the support mandrel, wherein the longitudinal yarns are deposited in corresponding corridors and these yarns are maintained in the corridors at the level of said concave part. The invention also relates to a machine for carrying out this process.
