Carbon fibre certainly isn't stronger than steel, thickness for thickness. Hit a sheet of 1mm thick carbon with a big hammer then do the same with a 1mm thick sheet of steel. Which one shattered?
Let me re-phase. I am not a fan of that style of louvered hood. To me it looked too many styles or effects attempted in one example. However, sometimes a carbon fibre hood or other components can work well with a specific design theme.
I was not speaking as to the strength and other aspects of glass and fibre vs metals. That is an argument proven by others already.
