Computational And Experimental Analysis Of Composite Overwrap Repair Of Butt Joint Pvc Pipes

Computational and Experimental Analysis of Composite Overwrap Repair of Butt-joint Pvc Pipes

Fiber reinforced polymer (FRP) composite materials are studied and used in the repair of pipeline systems. During the last few decades, researchers have mostly focused on the repair of rigid pipe rather than plastic pipe. An experimental and computational comparison study for several repair methods is conducted to determine the feasibility of E0́3glass/epoxy overwrap repairing butt joint pipes under pure bending. An undamaged pipe group and a coupler fitting repair group are also tested for comparison purposes. The test results indicate both coupler fitting and FRP composite overwrap repair can provide at least full moment capacity equivalent to undamaged pipes. However an FRP composite overwrap may alter the load carrying mechanism of the flexible system and result in brittle failure rather than the original ductile failure mode.

The Engineering Index Annual

Since its creation in 1884, Engineering Index has covered virtually every major engineering innovation from around the world. It serves as the historical record of virtually every major engineering innovation of the 20th century. Recent content is a vital resource for current awareness, new production information, technological forecasting and competitive intelligence. The world?s most comprehensive interdisciplinary engineering database, Engineering Index contains over 10.7 million records. Each year, over 500,000 new abstracts are added from over 5,000 scholarly journals, trade magazines, and conference proceedings. Coverage spans over 175 engineering disciplines from over 80 countries. Updated weekly.
