High-Performance Plastic Sled Design for Polar Traversing
Over-snow resupply traverses in Antarctica and Greenland tow high-efficiency fuel sleds that consist of flexible fuel bladders strapped to flexible sheets of high molecular weight polyethylene (HMW-PE). Despite low towing stresses, initial HMW-PE sheets were prone to cracking and failure within 1 to...
