An investigation into the fatigue behaviour of a glass fabric – epoxy composite used to repair pipeline defects

This paper outlines the methodology and the results of the experimental analysis performed by the authors regarding the fatigue behaviour of wraps made of new composite materials, obtained by the reinforcement with glass fibre fabric of an epoxy matrix, applied for repairing metal loss defects on steel pipes of oil, liquid petroleum and natural gas transmission pipelines. The information herein and the aspects explained in this paper must be used for determining the thickness of composite material wraps used to repair pipelines.
