Abstract
The invention proposes a splitter lip for a low-pressure compressor of an axial turbomachine for an aeroplane. The splitter lip comprises an upstream annular wall made of metal with a circular leading edge, and a downstream annular partition made of an organic-matrix, short-fiber composite material. The splitter lip also supports an outer shroud for a stator upstream of the compressor. The upstream wall comprises an annular anchoring portion arranged in the thickness of the downstream partition so as to anchor the partition and the wall to one another. The anchoring portion has distributed hexagonal openings in order to increase anchoring. The invention also proposes a method for producing, by molding, a bi-material splitter lip or a mixed lip.
