Insulating segment for e.g. exhaust gas turbo charger, of supercharged internal combustion engine, has protection unit for protecting insulating core in edge area, where unit has insulating protective band for surrounding core in edge area

摘要

The segment has an insulating core (1) with a base surface (11), an external surface (12) and an edge area (13), and a protection unit for protecting the insulating core in the edge area. The protection unit has an insulating protective band (32) for surrounding the insulating core in the edge area, where the protective band has a fiber glass reinforcement. The protective band is inserted in the area of the external surface between the insulating core and a cover foil (2), which partially covers the external surface of the insulating core. An independent claim is also included for a method for fastening an edge protective band at an insulating core of an insulating segment.
