摘要：

The present paper investigates thick-walled composite pipes subjected to simultaneous multi-axial loads common to those experienced in coiled tubing applications. The pipes were assumed to be filament wound carbon fiber-epoxy laminates with multiple layers and variable fiber orientations. MATLAB-based software was used to calculate stresses and carry out failure analyses through the thickness of the pipes when subjected to pressure, axial and bending (spooling) loads. Analyses were performed to determine if the composite tubes could achieve comparable strengths and spooling diameters as equivalent steel tube geometries.
