Co-injected composite shroud of an axial turbomachine compressor

摘要

The segment (18) has a body with an arcuate profile made of a polymeric material, and a working surface on the body, where the working surface is made of another polymeric material injected with the former polymeric material. The working surface corresponds to an inner face of the shell (12), and the latter polymeric material includes predominantly silicone or Teflon(RTM: PTFE). The working surface is a surface structured to fit the profile of a stator blade (6), where the latter polymeric material ensures a seal with the stator blade. An independent claim is also included for a method for manufacturing a segmented stator blade shell of an axial turbomachine.
