Abstract
A method for preparing a root of a blade for mounting a turbomachine blade, made of composite material, in a root support, the method including positioning, on a side wall of the root of the blade, an anti-wear layer including synthetic fibres coated or impregnated with a bonding agent; polymerising the bonding agent such that the anti-wear layer adheres to the side wall of the root of the blade; and machining a free outer surface of the anti-wear layer intended to be in contact with the root support, so as to obtain a precision-ground outer surface.
