(b) Carbon fiber reinforced composite materials are not used in space vehicles

(c) Re-cyclability of composite material is poor

(d) Processing of composite material is difficult

The question was posed to me during an online exam.

I want to ask this question from Engineering  Materials topic in division Materials and their Properties of Engineering Chemistry I

Answer 1

The correct option is (b) Carbon fiber reinforced composite materials are not used in space vehicles

To explain I would say: Carbon fiber reinforced composite materials are used in space vehicles. All the other options are correct. Composites are optically opaque materials, re-cyclability of composite material is poor and its processing is difficult.
