Development of multilayer composite systems via co-extrusion process

Extreme conditions in Oil and Gas industry often impose conflicting demands for the optimum mechanical properties as well as long term corrosion resistance. The internal and external side of the pipeline are usually exposed to different environments and are required to possess different characteristics. It is difficult to find a single material to satisfy all above requirements. Therefore, the utilization of the conventional polymers could force undesirable modifications to the pipe characteristics or the operating conditions. An effective approach, to overcome this problem, could be the use of a composite (multilayers) pipe where the different layers strongly bonded to ensure stability in the extreme operating conditions. In this project, we aim to investigate key parameters of the co-extrusion, select the proper materials for the manufacturing of multilayers systems, and characterize the multilayer structures as wells as properties of final multilayer systems.
