abstract
Hybrid composite tubulars are one of the unique structures that illustrate the tailorability of composites to offshore operating conditions. Herein, the focus is on filament wound composite tubulars that have glass and carbon as reinforcing fibers within the same thermoset matrix. In the present research program, the multiple scales associated with the material constituents and the geometric configuration are analytically and experimentally examined. The results to data indicate that the implementation of a progressive failure criteria in the finite element procedure accurately captures the response observed in testing of pressurized composite tubes. Structural similitude is used to relate the behavior of model tubes to candidate prototypes capable of withstanding the dynamic loads associated with currents and waves.
