Some very interesting articles, which I ignored and caught my attention, which I would like to share.
The first plastic bridge in the world
in Friedberg in Hesse state in Germany will release the first plastic bridge in the world and is ready for use. The bridge is built by plates of fiber-reinforced polymer (FRP) mounted on two steel beams and it meets all construction standards of the European Union.
construction costs are relatively higher, but are constrained strongly with lower maintenance costs, because while traditional bridges need maintenance after 20 years of use, this plastic is estimated to need it after 50 years as it does not suffer the effects of corrosion.
The bridge is relatively small, has a length of approximately 27 meters, a width of almost 5 meters long and weighs only 80 tons. The parts are manufactured item and were mounted in a single day.
The materials science is a branch of engineering with further evolution, as changing conditions and increasingly demanding that engineers do seek new materials for construction and the bridge is a good example of this.
recycled plastic bridge can handle more than 70 tons
The U.S. Army has shown the world's first bridge made from recycled plastic capable of withstanding heavy loads, at least 70 tons is the weight of a M1 Abrams tank with which it was tested (the test is shown in the video that accompanies this post).
As I said the bridge is constructed entirely from plastic derived from recycled bottles and the like, is the first such structure can withstand, according to its creators, loads greater than 70 tons of weight, said soon. This bridge has more advantages over the "usual" as being plastic resists corrosion better than other built in materials such as iron, resulting in a significant reduction in maintenance expenses.
we see in the future bridges of plastic? It is likely but will not be tomorrow, it is a foundation stone but still need further research and testing. This type of structure must be one hundred percent secure the lives of many people will pass over them.
