Thank you for your corrections! I'll be grateful! Do you know of any industries that could take advantage of composites that weren’t mentioned in the lecture? Why might a manufacturing company be slow to embrace the use of composites? In railway industry like aeronautical, aerospace and automotive, they need to reduce the consumption of fuel, but at the same time, they need structures and components with high mechanical properties, so in that case they could take advantage of composite materials. I also think that another industry could be metallurgic industry, more specifically, bridges building, because in many cases, for example a bridge over sea, bridge is exposed to corrosion, besides the bridge is subjected to many static strength and dynamic strength, which could be avoided with composite materials. The disadvantage and the reason which manufacturing companies be slow to embrace the use of composite materials, could be the price of composite materials because it is very high.
