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? 
 

The railway industry, like aeronautical, aerospace and automotive, needs to reduce the consumption of fuel. At the same time, the railway industry needs structures and components with high mechanical properties, so they can take advantage of composite materials. I also think that another industry could be metallurgic industry, more specifically, building bridges. Because in many cases, for example, a bridge over sea is exposed to corrosion. Besides that, the bridge is subjected to much static strength and dynamic strength, which could be avoided with composite materials.

The reason why manufacturing companies are slow to embrace the use of composite materials could be because the price of composite materials are very high.
