Composite pipe having a PTFE inner layer and a covering layer of a fiber-reinforced plastics material

摘要

A composite pipe includes a polytetrafluoroethylene (PTFE) inner layer and a covering layer of fiber-reinforced plastics material which are joined to one another by force-locking and form-locking through an intermediate layer. The intermediate layer is formed of a PFA layer and a layer of glass or carbon fibers, in order to improve adhesive and shear strength between the PTFE inner layer and the covering layer. The PFA layer is adjacent the PTFE inner layer and the layer of glass or carbon fibers is adjacent the covering layer of fiber-reinforced plastics material.
