Abstract
A segmented composite shell for an axial turbomachine compressor, each segment formed of a first polymeric material and comprises at least one working surface formed of a second polymeric material co-injected with the first polymeric material. The working surface can be a contact surface with a blade, wherein the working surface has a lipped profile and is made of an elastomeric material. The working surface can be the inner surface for bonding an abradable material, wherein the material can be silicone to facilitate the bonding of the abradable material to the silicone base. The working surface can be a lateral face of the shell that contacts a mating fixed surface, wherein the material can comprise TEFLON®, i.e. Polytetrafluoroethylene (PTFE), so as to form a working surface with dry friction properties. Such features enable the shell to have additional technical features implemented directly during the injection moulding of the shell segments.
