  • FIBRE-REINFORCED HOLLOW BODY FOR CHANNELLING MEDIA, IN PARTICULAR, CHEMICALLY AND/OR MECHANICALLY AGGRESSIVE MEDIA
    Publication number: 20180119849
    Abstract: The invention relates to a fibre-reinforced hollow body (10) for channelling media, in particular, chemically and/or mechanically aggressive media, for example, of the chemical industry and/or the process industry, having a base body (20), comprising a material containing fibres, and having a protective layer (40) for protecting the hollow body (10) against chemical and/or mechanical attacks. The protective layer (40) is formed from a fibre-free material or a substantially fibre-free material. The invention relates to a chemical composition for forming a protective layer (40) of a hollow body (10) for channelling media, in particular chemically and/or mechanically aggressive media, said protective layer protecting against chemical and/or mechanical attacks. Furthermore, the invention relates to method for producing a hollow body (10) for channelling media, in particular chemically and/or mechanically aggressive media, for example, of the chemical industry and/or the process industry.

  • Composite pipe having a PTFE inner layer and a covering layer of a fiber-reinforced plastics material
    Patent number: 6758245
    Abstract: 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.
