摘要：
A flexible duct (10) comprises either fully fluorinated polymers as internal liner (14), or fluoropolymers comprising an ethylene group or an alkoxyl group as internal liner (14). The flexible duct (10) further comprises a polymer filler (16), at least two layers of elongated steel members (18) as reinforcement. The elongated steel members have a tensile strength of at least 2000 MPa. The elongated steel members are embedded in the polymer filler so as to form a fully-bonded structure.
