Based on the Topic Description of the Clean Sky Project 'Non-metallic Pipes for Aero engine Dressings', a new concept for pipes and end fittings has been developed. This concept can be categorised as a paradigm as it will replace the existing technology that has driven the design of aero engine dressings for more than half a century. One of two different low cost manufacturing methods is used according to the composite matrix type (thermoset or thermoplastic). A novel CNC based process is being developed to form multiple bends in thermoplastic matrix pipes; this method will dramatically simplify the production of complex geometry fibre reinforced composite pipes. A new approach to fire resistance based on proprietary information of the partners will be full-scale tested in a near future. Based on the test results obtained to date it is expected that the requirements of the demanding standard ISO 2685-1998 - 'Aircraft - Environmental test procedure for airborne equipment - Resistance to fire in designated fire zones' will be fulfilled. The use of computerized tomography inspection will provide sufficient information to ensure the quality of prototype parts. This system is to expensive at the time being to be considered as a standard for series production. The use of UT Lamb-waves combined with the existing Nadcap requirements for special processes in composites manufacturing is envisaged as a more cost efficient system for quality assurance. New connection methods for bonding end fittings are being developed in parallel with the pipes and appear very promising. The connections will be full scale tested in the near future along with new concept end fitting designs which offer a mass saving of up to 50%.
