Abstract
A sector for a turbine stator includes vanes made of composite material, each including an airfoil extending between first and second ends. The sector has first and second platforms made of composite material, the first platform having openings in which the first ends of the vanes are engaged, and the second platform having openings in which the second ends of the vanes are engaged. The openings in the first platform present dimensions greater than the dimensions of the first ends of the vanes engaged in the openings so as to leave clearance between the first end of each vane and the opening. Each vane first end engaged in an opening presents dimensions that are less than the dimensions of the airfoil so as to define a shoulder extending around the first end. The shoulder presents dimensions that are greater than the dimensions of the openings in the first platform.
