You may be correct. Take aircraft construction for example. Right now carbon fiber is quickly becoming the material of choice for bodies and empennages. I would think a composite material consisting of alternating layers of graphene and carbon fiber would be thinner and therefore lighter yet have the same level of strength as all carbon fiber construction. The weight savings would be significant.
Absolutely. And bridges and roads. Graphene will mean the end of potholes, one way or the other.
But thats only scratching the surface.
The electronic and optical potential of graphene is at least as exciting as are its mechanical and structural properties.
Autocorrect inserted a spurious apostrophe there.
