Bridge made of recycled plastic supports 70-ton tank
The M1 Abrams is one of the heaviest main battle tanks - and therefore one of the heaviest ground vehicles - in current service, with modern examples generally tipping the scales at over 70 tons.
The recyclothermoplast material comes from makers Axion International, who developed it in cooperation with boffins at Rutgers University. The firm sees it as taking on many structural and building tasks in coming years, replacing "last-generation materials, such as wood, steel or concrete".
