[quote]民航大学航空工程学院院长徐建新:波音787的最大优势,一个是它采用了先进的碳纤维材料,用量已经达到了50%多,目前国际市场上和它同类的最先进的飞机材料用量只在20%多。这种材料的大量使用,可以使飞机的重量下降,意味着飞机在飞行时燃油的消耗会降低,和同类飞机相比,这款飞机的燃油消耗量可以降低20%左右。
So far, it has NOT discovered a way to deposit these materials. For the view of environment, these composite materials are no difference from the plastic bag in supermarket. Nobody knows how to deal with retired composite material airplanes yet.
Who cares? It has another 30 yrs to come.
More resin based composite materials used in sports and military equipment, cars, and hobby toys that is currently going into landfills quite possibly already exceed what is projected to end up being recycled from these aircraft 30 to 100 years from now. My broken Komperdell Composite trekking poles from REI are already on their way to the landfill as of today. :cry: :evil: |
