Aerospace Materials Used to Build 'Endless' Pipeline (ScienceDaily, Aug. 17, 2012)
Mo Ehsani, Professor Emeritus of Civil Engineering at the University of Arizona, has designed a new, lightweight underground pipe he says could transform the pipeline construction industry.Instead of conventional concrete or steel, Ehsani's new pipe consists of a central layer of lightweight plastic honeycomb, similar to that used in the aerospace industry, sandwiched between layers of resin-saturated carbon fiber fabric.In combination, these materials are as strong, or stronger, than conventional steel and concrete pipes, which are time-consuming and expensive to manufacture and transport.
